Outside-Session Access to Entity fetched in Session fails
---------------------------------------------------------
Key: OPENJPA-1523
URL: https://issues.apache.org/jira/browse/OPENJPA-1523
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.0.0-beta
Environment: Windows
Reporter: bernard
Priority: Critical
Attachments: OutOfSession.zip
I am planning to migrate from TopLink Essentials. The application has an EJB
tier so presentation logic must have access to Entity POJOs as feched in a
session bean. That should not a problem with the control provided by JPA
fetching.
With TopLink Essentials fetching works well under GlassFish V2 and in Java SE
standalone tests.
However OpenJPA fails in the attached testcase that closely maps the type of
problem that we are facing in the container.
The workaround would be to "touch" all required properties in the session bean
before the entities leave the persistence context. Such a workaround is not
practical.
The attached testcase has a TopLink version for comparison. In both cases, a
command line parameter has to be configured to match the absolute path:
-javaagent:dist\lib\openjpa-all-2.0.0-beta.jar
and
-javaagent:toplink-essentials-agent.jar
A switch CREATE_DATA_FIRST_TIME has to be set in the source code.
The testcase was created with the NetBeans IDE which includes the referenced
TopLink library.
