Subject [jira] Closed: (OPENJPA-1523) Outside-Session Access to Entity fetched in Session fails
Date Mon, 22 Feb 2010 04:40:27 GMT

     [ https://issues.apache.org/jira/browse/OPENJPA-1523?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

bernard closed OPENJPA-1523.
----------------------------

    Resolution: Invalid

JSR 317 about EntityManager getReference:

"The application should not expect that the instance state will be available upon detachment,
unless it was accessed by the application while the entity manager was open."

Therefore, this is not a bug in the sense I thought it was. The fact that TopLink Essentials
provides instance state upon detachment should not really matter here. Closing.

> 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.
