Envers classloading problem (Jboss7 second instance from quartz)

[tomsmith]

Ok, this will be extremely wired but I hope you can get through my problem:

I have a fully working jboss7 ejb3 application with envers revisioning. The application is running without problems and is registering it's hibernate sessionFactory in jndi at startup.

From this application there is a MailQueueJob started as Quartz job. This job tries to send generated mails asynchronous.

Envers seems to use a different class loader in the job and fails to load my class.

This job is getting its sessionfactory through jndi, opens a new session and requests the UserTransaction from jboss jndi:

initCtx = new InitialContext();

tx = (UserTransaction)initCtx.lookup("java:jboss/UserTransaction");

from this sqlSession several criteriaQueries are started. no problems.

The following block fails. It should read out the latest revision from given invoice.

AuditReader reader = AuditReaderFactory.get(sqlSession);

Number revisionNumber = reader.getRevisions(Invoice.class, mail.getInvoice().getId()).get(0);

Invoice oldInvoice = reader.find(Invoice.class, mail.getInvoice().getId(), revisionNumber);

No idea unfortunately, but if it's still a problem, you may try postsing on the AS7 mailing list, as it looks like a classloading problem.

No idea what's going wrong...

I know its quite late to post here, but I am also facing same issue in WebSphere 8.5 App Server.

I have a Quartz Job which invokes a piece of code containing Envers Query. When Quartz trigger the job, the Envers Query failing with exception saying, ClassNoFoundException for one of the class in my domain model. But same piece of code is working fine, if I invoke it using a User Interface button.

Can anyone suggest a solution or why it is happening? Thank you.
