About JDOQL Queries

The Enterprise JavaBeans Specification, v1.1 does not specify the format of the finder method description. The Enterprise Server uses an extension of Java Data Objects Query Language (JDOQL) queries to implement finder and selector methods. You can specify the following elements of the underlying JDOQL query:

The Enterprise Server specific deployment descriptor (sun-ejb-jar.xml) provides the following elements to store the EJB 1.1 finder method settings:


The bean developer uses these elements to construct a query. When the finder method that uses these elements executes, the values of these elements are used to execute a query in the database. The objects from the JDOQL query result set are converted into primary key instances to be returned by the EJB 1.1 ejbFind method.

The JDO specification, JSR 12, provides a comprehensive description of JDOQL. The following information summarizes the elements used to define EJB 1.1 finders.
