session bean not working anymore on v 4.0.2

miclon May 6, 2005 12:50 PM

Since I upgrade to V 4.0.2I got this exception

17:47:50,531 INFO [STDOUT] EJB (ejb/AppSessionB) Connexion Exception : null
17:47:50,531 INFO [STDOUT] java.lang.ClassCastException
17:47:50,531 INFO [STDOUT] at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:293)

Was working fine on 4.0.1 and before

Any idea ?

Thanks

Mik

Read the release notes on the class loading changes.

Hi Scott, I've read the wiki on:

http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration

And I understand the needs for these changes but I've not found an example on how to configure my applications with this new classloading mechanism.
Could you explain it with an example?

Of course if I revert to:
<attribute name="Java2ClassLoadingCompliance">true</attribute> <attribute name="UseJBossWebLoader">true</attribute>

everything works again.

Thank you in advance

Have you read the wiki on ClassLoader use cases?

Yes, both the wikis, but as I told, what I have to chanage into my existing apps to get it working again?
I see some in depth nice classloading explanations but I do not see a pratical example as for this comment:

http://jira.jboss.com/jira/browse/JBAS-1691#action_12317322

Thank you in advance.

Hi,

have a similar problem, on a utility class,
in a package (...tools..) I have 2 classes,
the first class is found, the second NOT !

If I change the
attribute name="Java2ClassLoadingCompliance"
attribute name="UseJBossWebLoader"
to true it works,

this is strange.

Thanks
