EJB3 JPA does not define stored procedure execution. There is a native query in JPA, but this is mainly for SQL. If you stored procedure has no output parameters you can normally get away with using a native query to execute it (be sure to include BEGIN/END in Oracle).
<p>
In TopLink 11g preview there are JPA extensions for defining stored procedures. You can use the @NamedStoredProcedureQuery for this, and then access the named query by name and execute it. You can also create an instance of a TopLink StoredProcedureCall and set it in your JPA Query through the TopLink Query extension setDatabaseQuery(), or define the named stored procedure query using a DescriptorCustomizer.
<p>
In TopLink Essentials there is no direct stored procedure support, so you would need to use JDBC directly.
<p>
If you are using a DataSource in your application the best way to get a JDBC connection is to use your DataSource directly. If the DataSource is JTA managed this will be the same connection that TopLink writes with.
<p>
If you need to get the connection directly from TopLink you can use,
((oracle.toplink.<essentials>.ejb.cmp3.EntityManager)entityManager.getDelegate()).getUnitOfWork().getConnection();
<p>
You may need to first call, UnitOfWork.beginEarlyTransaction(), (also ensure you release the uow connection).
