Re: [eclipselink-users] dynamic weaving now possible with jBoss 5 ? Any

["Michael O'Brien" <michael.obrien@xxxxxxxxxx>]

Manfred,
    Hi, we have an update on dynamic weaving on JBoss 5.0.1.
    Kevin verified that we still get the NullPointerException in their UniversalClassLoader3 described by JBoss JIRA-572 - it looks like the JEE5 specification call - PersistenceUnitInfo.getNewTempClassLoader() is still not fixed in JBoss 5.0.1 - the JIRA is still open as well.

See our workaround/log for the NPE in PersistenceUnitProcessor https://bugs.eclipse.org/bugs/show_bug.cgi?id=227630 https://bugs.eclipse.org/bugs/attachment.cgi?id=96619&action="">
You will see the following message until JIRA-572 is fixed on their end

        } catch (NullPointerException npe) {
            // Bug 227630: If any weavable class is not found in the temporary classLoader - disable weaving
            AbstractSessionLog.getLog().log(AbstractSessionLog.WARNING, "persistence_unit_processor_error_loading_class_weaving_disabled", loader, project.getPersistenceUnitInfo().getPersistenceUnitName(), className);

{ "persistence_unit_processor_error_loading_class_weaving_disabled", "The classLoader [{0}]: for PersistenceLoadProcessor [{1}] failed to load class [{2}]. Weaving has been disabled for this session. EclipseLink may be unable to get a spec mandated temporary class loader from the server, you may be able to use static weaving as an optional workaround. "},

The tracking bug# 252965 should remain in future state for Jira 572 until it is fixed in a later JBoss release.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252965

You may vote for EJBTHREE-572 to be fixed by creating an account and voting for this JIRA.

Manfred,
    Hi, good question.  Yes, the latest JBoss 5.0CR2 (Oct 2008) release should be fully JEE5 compliant with a temporary ClassLoader that we can use to do dynamic weaving.  This just needs to be fully tested with a possible JBoss 5 platform addition so we support users before/after 5.0CR2.  I would like to verify this asap.


    See outstanding 252965 design change to verify JBoss 5.0CR2

     You may track and/or edit this bug.


   See original workaround for JBoss 4/5.

Subject: [eclipselink-users] dynamic weaving now possible with jBoss 5 ? Any experiences?


Hi,

since my last question here concerning static weaving received no
answers I'll now try a second approach our problem: instead of static
weaving I'd like to use dynamic weaving with jBoss 5.

Should this be possible now with the jBoss 5 version or is it still
recommended to use the static-weaving workaraound also for jboss 5?

Any users here with experiences in this combination (ecliselink & jBoss 5) ?


Regards,
Manfred
