Subject [jira] Commented: (OPENJPA-794) issues with closing/opening entity manager (slices) (can't seem to be able to create multiple entityManagers )
Date Mon, 01 Dec 2008 00:50:44 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651891#action_12651891
] 

Fernando commented on OPENJPA-794:
----------------------------------

the root cause of this bug is that slices does not work with QueryCompilationCache..

Issue OPENJPA-797, is asking for this restriction to be posted in the Documentation.

This bug can either be closed (accepting the restriction), or be kept open to see if we can
change the code to lift this restriction..

I would say close this one for now (duplicate of 797).

> So, for each of my web requests I open an entitymanager at the begining, and close it
at the end, something like this:
> EntityManager pm = pmf.createEntityManager();
> try {
>  chain.filter(...);
> }
> finally {
>  pm.close();
> }
> And this works perfectly without slices.  But when I turn on slices, this fails.  The
first request works fine, but the second requests complains that the EntityManager has already
been closed.  So it seems to be caching the EntityManager from the previous request...  can
someone please help me figure out how to fix this??
> I'll attach the log.
