Re: [eclipselink-users] EclipseLink in Glassfish, roundup

[James Sutherland <jamesssss@xxxxxxxxx>]

This is very odd; I cannot think what could be causing the issue.  Do you get
any errors during deployment?  Try setting logging to finest and see if
anything odd is occurring.

You should not be starting Glassfish with the agent; the weaving should
occur from the EJB 3.0 container contract the same as it did with TopLink
Essentials.  However weaving is not required for lazy collections, so
weaving should not have any effect.  It could have something to do with the
weaving of change tracking, so you could try turning weaving off in your
persistence.xml and see if the issue still occurs.

By the way, does the same application work with TopLink Essentials, or do
you get issues as well?

Could you include the full exception stack trace with the error from M4.

I will try to run our JPA server tests in Glassfish to see if I get the same
issue as you are seeing.
