This section lists each TopLink error code. Each error entry contains a description of the error, the probable cause, and the recommended action. Each error code corresponds to an exception class. See "Runtime and Development Exceptions" for more information.
A description shown in the actual exception thrown.
Cause: The most probable cause for the error.
Action: Suggestions for resolving the error.
ATTRIBUTE_AND_MAPPING_WITH_INDIRECTION_ MISMATCH
Cause: <attributeName> is not declared as type ValueHolderInterface but the mapping uses indirection. Mapping is set to use indirection but the related attribute is not defined as type ValueHolderInterface. It is thrown on foreign reference mappings.
Action: If you want to use indirection on the mapping, change the attribute to type ValueHolderInterface. Otherwise, change the mapping associated with the attribute so that it does not use indirection.
ATTRIBUTE_AND_MAPPING_WITHOUT_INDIRECTION_ MISMATCH
Cause: <attributeName> is declared as type ValueHolderInterface but the mapping is not using indirection. Attribute is defined to be of type ValueHolderInterface but the mapping is not set to use indirection. It is thrown on foreign reference mappings.
Action: If you do not want to use indirection on the mapping, change the attribute to not be of type ValueHolderInterface. Otherwise, change the mapping associated with the attribute to use indirection.
ATTRIBUTE_NAME_NOT_SPECIFIED
Cause: Attribute name is missing or not specified in the mapping definition.
Action: Specify the attribute name in the mapping by calling method setAttributeName(String attribute name).
ATTRIBUTE_TYPE_NOT_VALID
Cause: <attributeName> should be defined as type Vector, or a type that implements Map or Collection if using Java 2. It happens in one to many mapping, many to many mapping and collection mapping when mapping is set not to use indirection and attribute type is not declared of type java.util.Vector.
Action: Declare the attribute to be of type java.util.Vector.
CLASS_INDICATOR_FIELD_NOT_FOUND
Cause: The class indicator field has not been defined, however the descriptor has been set to use inheritance. When using inheritance, a class indicator field or class extraction method must be set. The class indicator field is used to create the right type of domain object
Action: Either a class indicator field or class extraction method must be set.
DIRECT_FIELD_NAME_NOT_SET
Cause: The direct field name from the target table is not set in the direct collection mapping. The field values form the collection in this mapping.

Cause: The field name is not set in the mapping. It is thrown from direct to field mapping, array mapping and structure mapping.
Action: Specify the field name by calling method setFieldName(String fieldName).
FOREIGN_KEYS_DEFINED_INCORRECTLY
Cause: One to one mapping foreign key defined incorrectly. Multiple foreign key fields were set for one to one mapping by calling method setForeignKeyFieldName(String fieldName).
Action: Use method addForeignKeyFieldName(String sourceForeignKeyName, String targetPrimaryKeyFieldName) to add multiple foreign key fields.
IDENTITY_MAP_NOT_SPECIFIED
Cause: The descriptor must use an identity map to use the Check cache does exist option. Descriptor has been set to not use identity map but the existence checking is set to be done on identity map.
Action: Either use identity map or set the existence checking to some other option.

Action: Inspect the internal exception and check the Java manuals.
INSTANTIATION_WHILE_CONSTRUCTOR_INSTANTIATION
Cause: he class does not define a public default constructor, or the constructor raised an exception. The default constructor for the domain object is invoked to create new instance of the object while building new domain objects. If this Class represents an abstract class, an interface, an array class, a primitive type, or void; or if the instantiation fails for some other reason. Java throws the error and TopLink only wraps the reflection exception.
Action: Inspect the internal exception and check the Java manuals.
INVALID_DATA_MODIFICATION_EVENT
Cause: This is an exception that an application should never encounter. The exception can occur at the time of developing TopLink. In cases where one writes new mapping it is possible to get this exception. In direct collection mapping and many to many mapping the target table and relational table are populated at the end of the commit process and if data modification event is sent to any other mapping then this exception is thrown.
Action: Contact Technical Support.
INVALID_DATA_MODIFICATION_EVENT_CODE
Cause: This is an exception that an application should never encounter. The exception can occur at the time of developing TopLink. In cases where one writes new mapping it is possible to get this exception. In direct collection mapping and many to many mapping the target table and relational table are populated at the end of the commit process and if data modification event is sent to these two mappings with wrong event code then this exception is thrown.
Action: Contact Technical Support.
INVALID_DESCRIPTOR_EVENT_CODE
Cause: This is an exception that an application should never encounter. The exception can occur at the time of developing TopLink. The exception means that descriptor event manager does not support the event code passed in the event.
Action: Contact Technical Support.
INVALID_IDENTITY_MAP
Cause: Identity map constructor failed because an invalid identity map was specified. The identity map class given in the descriptor cannot be instantiated. The exception is Java exception thrown by Java reflection when TopLink is instantiating the identity map class. TopLink only wraps the Java exception.
Action: Inspect the internal exception and check the Java manuals.
JAVA_CLASS_NOT_SPECIFIED
Cause: The descriptor does not define a Java class. The Java class is not specified in the descriptor.
Action: Specify the Java Class
DESCRIPTOR_FOR_INTERFACE_IS_MISSING
Cause: A descriptor for the referenced interface is not added to the session.
Action: Add that descriptor to the session.
MAPPING_FOR_SEQUENCE_NUMBER_FIELD
Cause: A non-read-only mapping is not defined for the sequence number field. A mapping is required so that TopLink can put and extract values for the primary key.
Action: Define a mapping.
MISSING_CLASS_FOR_INDICATOR_FIELD_VALUE
Cause: Missing class for indicator field value <classFieldValue> of type <type>. There was no class entry found in the inheritance policy for the indicator field value read from the database. Probably the method addClassIndicator(Class class, Object typeValue) was not called for the field value. The class and typeValue is stored in the hashtable and later on the class is extracted from the hashtable by passing typeValue as a key. Remember Integer(1) is not equal to Float(1), this is another major reason for this problem when the type of typeValue is different.
Action: Check descriptor.
MISSING_CLASS_INDICATOR_FIELD
Cause: The class indicator field is missing from the database row <row> that was read from the database. This is done in inheritance model where after reading rows from the database, child domain objects are to be constructed depending upon the type indicator values.
Action: Check the printed row to make sure the spelling is correct.
MISSING_MAPPING_FOR_FIELD
Cause: Missing mapping for field <field>; a mapping for the field is not specified.
Action: Define a mapping for the field.
NO_MAPPING_FOR_PRIMARY_KEY
Cause: A mapping for the primary key is not specified. There should be one non-read-only mapping defined for the primary key field.
Action: efine a mapping for the primary key.
MULTIPLE_TABLE_PRIMARY_KEY_NOT_SPECIFIED
Cause: The multiple table primary key mapping must be specified when a custom multiple table join is used. If multiple tables are specified in the descriptor and the join expression is customized then the primary keys for all the tables must be specified. If the primary keys are not specified then the exception is caused.
Action: Call method addMultipleTablePrimaryKeyFieldName(String fieldNameInPrimaryTable, String fieldNameInSecondaryTable) on the descriptor to set the primary keys.
MULTIPLE_WRITE_MAPPINGS_FOR_FIELD
Cause: There are multiple writable mappings for the field <fieldName> in the descriptor. Exactly one must be defined writable. The others must be specified as read-only. When multiple write mappings are defined for the field, TopLink cannot decide on which mapping to pick up for writing the value of the field in the database row hence the exception is thrown during the validation process of descriptors. The most common site for this problem is that sometimes the field has direct-to-field mapping and also one-to-one mapping. In this case if direct-to-field mapping has to be kept then one-to-one mapping should either be read-only or it should be target foreign key reference.
Action: Make one of those mappings read only.
NO_ATTRIBUTE_TRANSFORMATION_METHOD
Cause: The attribute transformation method name in the transformation mapping is not specified. This method is invoked internally by TopLink to retrieve value to store in the domain object.
Action: Define a method and set the method name on the mapping by calling method setAttributeTransformation(String methodName).
NO_FIELD_NAME_FOR_MAPPING
Cause: No field name is specified in direct-to-field mapping.
Action: Set the field by calling setFieldName(String FieldName).
NO_FOREIGN_KEYS_ARE_SPECIFIED
Cause: Neither the selection criteria nor the foreign keys were specified on one-to-one mapping. If the selection criterion is not specified then TopLink tries to build one from the foreign keys specified in the mapping.
Action: Specify the fields.
NO_REFERENCE_KEY_IS_SPECIFIED
Cause: No query key named: <queryKey> found in: <descriptor>; no reference key from the target table is specified on direct collection mapping.
Action: Specify the fields by calling method setReferenceKeyFieldName(String fieldName).
NO_RELATION_TABLE
Cause: The relation table name is not set in this many-to-many mapping.
Action: Set relation table name by calling method setRelationTableName(String tableName).

Action: Usually such exceptions would mean restarting the application but it is totally dependent on the application.
SIGNAL_ATTEMPTED_BEFORE_WAIT
Cause: A signal was attempted before wait on concurrency manager. This normally means that an attempt was made to commit or rollback a transaction before it was started, or to rollback a transaction twice.
Action: Check transactions in the application.
COULD_NOT_BE_CONVERTED
Cause: The object <object> of class <objectClass> could not be converted to <javaClass>. The object cannot be converted to given type.
Action: Check that the object being converted is of right type or not.
INCORRECT_DATE_FORMAT
Cause: The date in <dateString> is in an incorrect format. Expected format is YYYY-MM-DD.
Action: Check the date format.

Cause: The driver class name was not found.
Action: Check the class name given in JDBCLogin.
DATABASE_ACCESSOR_NOT_CONNECTED
Cause: Session is not connected to the database while doing reading or writing on the database.
Action: An application may have to login again because the connection to the database might have been lost.
ERROR_READING_BLOB_DATA
Cause: Error reading blob data from the database. There are two possibilities for this exception, first is that the blob data was not read properly from the result set or the TopLink could not process the blob data using ByteArrayOutputStream.
Action: Check if the underlying driver support blobs properly or not and if it does then report this problem to Technical Support.
OULD_NOT_CONVERT_OBJECT_TYPE
Cause: Could not convert object type on internal error. java.sql.TYPES = <type>. The object from the result set cannot be converted to the type returned from the metadata information.
Action: Check if the underlying driver support the conversion type properly or not and if it does then report this problem to Technical Support.
LOGOUT_WHILE_TRANSACTION_IN_PROGRESS
Cause: An attempt has been made to logout while the transaction is still in progress. You cannot logout while a transaction is in progress.
Action: Wait until the transaction is over.
SEQUENCE_TABLE_INFORMATION_NOT_COMPLETE
Cause: The sequence information given to TopLink is not sufficiently complete to get the set of sequence numbers from the database. This usually happens on native sequencing on oracle database.
Action: Check the data given specially the sequence name given in TopLink.
ERROR_PREALLOCATING_SEQUENCE_NUMBERS
Cause: Error preallocating sequence numbers on the database; the sequence table information is not complete.
Action: Check if the sequence table was created on the database properly or not.
CANNOT_REGISTER_SYNCHRONIZATIONLISTENER_ FOR_UNITOFWORK
Cause: Cannot register Synchronization Listener: underlying_exception_string. When the TopLink Session is configured with an ExternalTransactionController, any unit of work requested by a client must operate within the context of a JTS external global transaction. When a unit of work is created and the external global transaction is not in existence or if the system cannot acquire a reference to it, this error is reported.
Action: Ensure that a JTS transaction is in progress before acquiring the unit of work.
SYNCHRONIZED_UNITOFWORK_DOES_NOT_ SUPPORT_COMMITANDRESUME
Cause: Synchronized UnitOfWork does not support the commitAndResume operation. When the TopLink Session is configured with an ExternalTransactionController, any unit of work requested by a client must operate within the context of a JTS external global transaction (see Error code: 4014). The JTS specification does not support the concept of "checkpointing" a transaction, that is, committing the work done and then continuing to work within the same transaction context (JTS does not support nested transactions, either). Thus, if client code invokes commitAndResume() on a "synchronized" unit of work, this error will be reported.
Action: None.
CONFIGURATION_ERROR_NEW_INSTANCE_ INSTANTIATION_EXCEPTION
Cause: Configuration error. Attempting to instantiate Driver: <javaClass>. Could not instantiate driver.
Action: Check the driver.
CONFIGURATION_ERROR_NEW_INSTANCE_ILLEGAL_ ACCESS_EXCEPTION
Cause: A configuration error occurred while attempting to instantiate Driver: <javaClass>. Could not instantiate driver.
Action: Check the driver.
TRANSACTION_MANAGER_NOT_SET_FOR_JTS_DRIVER
Cause: The transaction manager has not been set for the JTSSynchronizationListener.
Action: Set a transaction manager for the JTSSynchronizationListener.
NO_VERSION_NUMBER_WHEN_DELETING
Cause: An attempt was made to delete the object <object> but it has no version number in the identity map. This object either was never read or has already been deleted.
Action: Logging SQL is very helpful in understanding the reason why the exception is thrown. The last delete will show the object we are deleting that throws an exception.
OBJECT_CHANGED_SINCE_LAST_READ_WHEN_DELETING
Cause: The object state has changed in the database. The object <object> cannot be deleted because it has changed or been deleted since it was last read. This usually means that the row in the table was changed by some other application.
Action: Refreshing an object will refresh the object with the new data from the database.
NO_VERSION_NUMBER_WHEN_UPDATING
Cause: An attempt has been made to update the object <object> but it has no version number in the identity map. It may not have been read before being updated or has been deleted.
Action: Logging SQL is very helpful in understanding the reason why the exception is thrown. The last update will show the object we are updating that throws an exception.
OBJECT_CHANGED_SINCE_LAST_READ_WHEN_UPDATING
Cause: The object state has changed in the database. The object <object> cannot be updated because it has changed or been deleted since it was last read. This usually means that the row in the table was changed by some other application.
Action: Refreshing an object will refresh the object with the new data from the database.
MUST_HAVE_MAPPING_WHEN_IN_OBJECT
Cause: The object <aClass> must have a non-read-only mapping corresponding to the version lock field. The mapping was not defined for the locking field. It is needed when the lock value is stored in the domain object than in a cache.
Action: Define a mapping for the field.
NEED_TO_MAP_JAVA_SQL_TIMESTAMP
Cause: A write lock value which is stored in a domain object is not an instance of java.sql.Timestamp.
Action: Change the value of the attribute to be an instance of java.sql.Timestamp.
ADDITIONAL_SIZE_QUERY_NOT_SPECIFIED
Cause: Cursored SQL queries must provide an additional query to retrieve the size of the result set. Custom queries using cursor streams and not specifying the size query will cause this exception. The size query is used to retrieve the size of the number of object read from the database. This is done on JDBC 1.0 compatible drivers because it provides no way to extract the size of the result set read. Non custom queries using cursor streams will have default queries generated by TopLink.
Action: Specify a size query.
AGGREGATE_OBJECT_CANNOT_BE_DELETED
Cause: Aggregated objects cannot be written or deleted independent of their owners. There is no identity maintained on such objects.
Action: Application's discretion.
ARGUMENT_SIZE_MISMATCH_IN_QUERY_AND_ QUERY_DEFINITION
Cause: The number of arguments provided to the query for execution does not match the number of arguments provided with the query definition.
Action: Check the query and query execution.
BACKUP_CLONE_IS_ORIGINAL_FROM_PARENT
Cause: The object <clone> of class <clone.getClass()> with identity hashcode (System.identityHashCode()) <System.identityHashCode(clone)> is not from this unit of work space but from the parent session. The object was never registered in this unit of work but read from the parent session and related to an object registered in the unit of work.
Action: Ensure that you are correctly registering your objects. If you are still having problems, you can use the UnitOfWork.validateObjectSpace() method to help debug where the error occurred. Please see the manual and FAQ for more information.
BACKUP_CLONE_IS_ORIGINAL_FROM_SELF
Cause: The object clone of class <clone.getClass()> with identity hashcode (System.identityHashCode()) <System.identityHashCode(clone)> is the original to a registered new object. The unit of work clones registered new objects, so you must ensure that it is registered before it is reference by another object. If you do not want the new object to be cloned, used the UnitOfWork.registerNewObject(Object) API.
Action: Ensure that you are correctly registering your objects. If you are still having problems, you can use the UnitOfWork.validateObjectSpace() method to help debug where the error occurred. Please see the manual and FAQ for more information.
BATCH_READING_NOT_SUPPORTED
Cause: This mapping does not support batch reading. The optimization of batching the read of all the target rows is not supported for the mapping.
Action: The problem is a TopLink development problem and user should never encounter this unless the mapping is a new custom mapping. Contact Technical Support.
DESCRIPTOR_IS_MISSING
Cause: Missing descriptor for <reference Class>. The descriptor related to the class or the object is not found in the session.
Action: Check if the related descriptor was added to the session or the query is done on the right object or class.
DESCRIPTOR_IS_MISSING_FOR_NAMED_QUERY
Cause: Missing descriptor for <domain Class Name> for query named <queryName>. The descriptor where named query is defined is not added to the session.
Action: Check if the related descriptor was added to the session or the query is done on the right class.
INCORRECT_SIZE_QUERY_FOR_CURSOR_STREAM
Cause: The size query given on the queries returning cursor streams is not correct. The execution of the size query did not return any size.
Action: If the cursor stream query was custom query than check the size query specified else report this problem to Technical Support.
INVALID_QUERY
Cause: Objects cannot be written in unit of work using modify queries, they must be registered.
Action: Objects are registered in the unit of work and during commit unit of work will do the required changes to the database.
INVALID_QUERY_KEY_IN_EXPRESSION
Cause: The query key <key> does not exist. Usually this happens because of mis-spelled query key.
Action: Check the query key specified in the expression and make sure that a query key was added to the descriptor.
INVALID_QUERY_ON_SERVER_SESSION
Cause: Objects and the database cannot be changed through the server session; all changes must be done through a client session's unit of work. The objects cannot be changed on the server session by modifying queries. Objects are changed in the client sessions acquired from this server session.
Action: Use client session's unit of work to change the object.
NO_CONCRETE_CLASS_INDICATED
Cause: No concrete class indicated for the type in this row. The type indicator read from the database row has no entry in the type indicator hashtable or if class extraction method was used, it did not return any concrete class type. The exception is thrown when sub classes are being read.
Action: Check class extraction method if specified or check the descriptor to see if all the type indicator values were specified or not.
NO_CURSOR_SUPPORT
Cause: No cursor support provided for abstract class multiple table descriptors using expressions.
Action: Consider using custom SQL or multiple queries. <query>
OBJECT_TO_INSERT_IS_EMPTY
Cause: There are no fields to be insert into the table. The fields to insert into the table, <table> is empty. You must define at least one mapping for this table
Action: Must define at least one mapping for this table.
OBJECT_TO_MODIFY_NOT_SPECIFIED
Cause: An object to modify is required for a modify query.
Action: Ensure the query contains an object before executing.
QUERY_NOT_DEFINED
Cause: Query is not defined. When executing query on the session the parameter which takes query is null.
Action: Check if the query is passed properly.
QUERY_SENT_TO_INACTIVE_UNIT_OF_WORK
Cause: The unit of work has been released and is now inactive.
Action: The unit of work, once released, cannot be reused unless commitAndResume is called.
READ_BEYOND_QUERY
Cause: An attempt has been made to read from the cursor streams beyond its limits (beyond the end of the stream).
Action: Ensure the stream is being checked for an "end of stream" condition before attempting to retrieve more objects.
REFERENCE_CLASS_MISSING
Cause: The reference class in the query is not specified. A reference class must be provided.
Action: Check the query.
REFRESH_NOT_POSSIBLE_WITHOUT_CACHE
Cause: Refresh is not possible if caching is not set. The read queries which skip cache to read objects cannot be used to do refresh the object. Refreshing is not possible without identity.
Action: Check query.
SIZE_ONLY_SUPPORTED_ON_EXPRESSION_QUERIES
Cause: Did not find size query. Size only supported on expression queries, unless a size query is given.
Action: Cursor streams on custom query should also define size query.
SQL_STATEMENT_NOT_SET_PROPERLY
Cause: The SQL statement has not been properly set. The user should never encounter this unless queries have been customized.
Action: Contact Technical Support.
INVALID_QUERY_ITEM
Cause: Invalid query item expression.
Action: Validate the Expression being used.
SELECTION_OBJECT_CANNOT_BE_NULL
Cause: The selection object passed to a read object or refresh was null.
Action: Check setSelectionObject() on the read query.
UNNAMED_QUERY_ON_SESSION_BROKER
Cause: Data read and data modify queries is being executed without the session name. Only object-level queries can be directly executed by the session broker, unless the query is named.
Action: Session broker has no idea about such queries about which session to execute the query on. Specify the session name.
REPORT_RESULT_WITHOUT_PKS
Cause: ReportQuery without PKs cannot readObject. The report query result returned is without primary key values. An object from the result can only be created only if primary keys were also read.
Action: Check documentation on retrievePriamryKeys() on report query.
NULL_PRIMARY_KEY_IN_BUILDING_OBJECT
Cause: The primary key read from the row, <databaseRow> during the execution of the query was detected to be null; primary keys must not contain null.
Action: Check query and also the table on the database.
NO_DESCRIPTOR_FOR_SUBCLASS
Cause: The subclass has no descriptor defined for it.
Action: Check session if the descriptor was added or not or else check class extraction method.
CANNOT_DELETE_READ_ONLY_OBJECT
Cause: Cannot delete an object of read-only class. The class <className> is declared read-only in this unit of work. Thrown in unit of work when trying to delete an object that is marked as read only.
Action: Contact Technical Support.
INVALID_OPERATOR
Cause: The operator <data> used in the expression is not valid.
Action: Check ExpressionOperator class to see a list of all of the operators supported.

Cause: The number of attributes requested does not match the attributes returned from the database in report query. This usually happens if one gives custom query on the report query.
Action: Check the custom query if it is specified or report this problem to Technical Support.
CANNOT_CACHE_PARTIAL_OBJECT
Cause: Partial Objects are never put in the cache. Partial object queries are not allowed to maintain the cache or be edited. You must set dontMaintainCache().
Action: Call the dontMaintainCache() method before executing the query.
OUTER_JOIN_ONLY_VALID_FOR_ONE_TO_ONE
Cause: An outer join (getAllowingNull) is only valid for one to one mappings, and cannot be used for the mapping.
Action: Do not attempt to use getAllowingNull for mappings other than one to one.

Cause: This expression cannot determine if the object conforms in memory, you must set the query to check the database.
Action: Change the query such that it does not attempt to conform to the results of the query.
INVALID_OPERATOR_FOR_OBJECT_EXPRESSION
Cause: Object comparisons can only use the equal or notEqual operators, other comparisons must be done through query keys or direct attribute level comparisons.
Action: Ensure the query uses only equal and notEqual if object comparisons are being used.
UNSUPPORTED_MAPPING_FOR_OBJECT_COMPARISON
Cause: Object comparisons can only be used with 1:1 mappings; other mapping comparisons must be done through query keys or direct attribute level comparisons.
Action: Use a query key instead of attempting to compare objects across the mapping.
OBJECT_COMPARISON_CANNOT_BE_PARAMETERIZED
Cause: Object comparisons cannot be used in parameter queries.
Action: Change the query such that it does not attempt to use object when using parameterized queries.
INCORRECT_CLASS_FOR_OBJECT_COMPARISON
Cause: The class of the argument for the object comparison is incorrect.
Action: Ensure the class for the query is correct.
