[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-572) PersistenceUnitInfo.getNewTempClassLoader()

Fri Feb 8 09:14:03 EST 2008

    [ http://jira.jboss.com/jira/browse/EJBTHREE-572?page=comments#action_12398911 ] 

Alexander Tsirel commented on EJBTHREE-572:
-------------------------------------------

Now PersistenceUnitInfo.getNewTempClassLoader();  returns not null ClassLoader, 
but during start of jboss with toplink when there is a lookup 
for oracle.toplink.essentials.platform.server.jboss.JBossPlatform class with this classloader
NPE is thrown.

I added some output to toplink - here is the output for this lookup.

17:05:01,446 INFO  [STDOUT] Inside PrivilegedAccessHelper, looking for: oracle.toplink.essentials.platform.server.jboss.JBossPlatform with classLoader: org.jboss.mx.loading.UnifiedClassLoader3 at ad962c{ url=file:/C:/jboss-4.2.1.GA/server/default/tmp/deploy/tmp42933javaEEApplication.ear ,addedOrder=0}

After this lookup we have:

17:05:01,462 WARN  [ServiceController] Problem starting service persistence.units:ear=javaEEApplication.ear,jar=EJB.jar,unitName=first
javax.persistence.PersistenceException: Exception [TOPLINK-28018] (Oracle TopLink Essentials - 2.0.1 (Build SNAPSHOT (02/08/2008))): oracle.toplink.essentials.exceptions.EntityManagerSetupException
