Common BEA WebLogic 7.0 Exceptions

The following are a few of the most common exceptions you may encounter when deploying JAR files with TopLink and BEA WebLogic Server 7.0.

Development Exceptions

Missing Persistence Type: Cause: There is no entry in the persistence.install file for TopLink CMP. This may occur if the TopLink installation was interrupted, or a BEA WebLogic Server Service Pack was applied. The exception message returned is:
Persistence type 'TopLink_CMP_2_0' with version 'X.0 which is referenced in bean 'Account' is not installed. The installed persistence types are: (WebLogic_CMP_RDBMS, 6.0), (WebLogic_CMP_RDBMS, 5.1.0), (WebLogic_CMP_RDBMS, 7.0)ERROR: ejbc found errors; Action: In the <WebLogic InstallDir>/weblogic700/lib/persistence directory, edit the persistence.install file to add a new line: TopLink_CMP_Descriptor.xml. You can also replace your existing persistence.install file with the version of the file in the <ORACLE_HOME>/toplink/config directory.

Missing Persistence Type: Cause: There is no entry in the persistence.install file for TopLink CMP. This may occur if the TopLink installation was interrupted, or a BEA WebLogic Server Service Pack was applied. The exception message returned is:
ERROR: atweblogic.ejb20.persistence.InstalledPersistence.initialize(InstalledPersistence.java:214)atweblogic.ejb20.persistence.InstalledPersistence.getInstalledType(InstalledPersistence.java:113)atweblogic.ejb20.deployer.MBeanDeploymentInfoImpl.getPersistenceType(MBeanDeploymentInfoImpl.java:584; Action: In the <WebLogic InstallDir>/weblogic700/lib/persistence directory, edit the persistence.install file to add a new line: TopLink_CMP_Descriptor.xml. You can also replace your existing persistence.install file with the version of the file in the <ORACLE_HOME>/toplink/config directory.

Wrong WebLogic Version: Cause: You are trying to compile your JAR file using BEA WebLogic Server 6.1. The exception message returned is:
ERROR: Error processing 'META-INF/weblogic-ejb-jar.xml': The public id, "-//BEA Systems, Inc.//DTD WebLogic 7.0.0 EJB//EN", specified in the XML document is invalid. Use one of the following valid public ids:"-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN""-//BEA Systems, Inc.//DTD WebLogic 6.0.0 EJB//EN"ERROR: ejbc found errors; Action: Compile using BEA WebLogic Server 7.0.

Missing Persistence Type: Cause: There is no entry in the persistence.install file for TopLink CMP. This may occur if the TopLink installation was interrupted or a BEA WebLogic Server Service Pack was applied. The exception message returned is:
Error from ejbc: Persistence type 'TopLink_CMP_2_0' with version 'X.0 which is referenced in bean 'Account' is not installed. The installed persistence types are: (WebLogic_CMP_RDBMS, 6.0), (WebLogic_CMP_RDBMS, 5.1.0), (WebLogic_CMP_RDBMS, 7.0).Persistence type 'TopLink_CMP_2_0' with version 'X.0 which is referenced in bean 'Account' is not installed. The installed persistence types are: (WebLogic_CMP_RDBMS, 6.0), (WebLogic_CMP_RDBMS, 5.1.0), (WebLogic_CMP_RDBMS, 7.0); Action: In the <WebLogic InstallDir>/weblogic7.0/lib/persistence directory, edit the persistence.install file to add a new line: TopLink_CMP_Descriptor.xml. You can also replace your existing persistence.install file with the version of the file in the <ORACLE_HOME>/toplink/config directory.

Error Loading Persistence Resource: Cause: The toplink.jar file is not properly set in your classpath. The exception message returned is:
java.lang.NullPointerExceptionatweblogic.ejb20.deployer.EJBDeployer.deactivate(EJBDeployer.java:1513)atweblogic.ejb20.deployer.EJBDeployer.undeploy(EJBDeployer.java:301)atweblogic.ejb20.deployer.Deployer.deploy(Deployer.java:875)atweblogic.j2ee.EJBComponent.deploy(EJBComponent.java:70); Action: Ensure that the classpath includes the <ORACLE_HOME>/toplink/jlib/toplink.jar file.
