[Installation, Configuration & DEPLOYMENT] - Hibernate exception when Classloader scoping enabled
by smpub2000
Jboss 4.2, I have an EAR file with EJBS and WARs. I have a third part library (Gigaspaces) that uses hibernate. With Class loader scoping disabled, everything works fine. However when I enable scoping, I get the following exception, even though I have ojdbc14.jar in lib directory at root of EAR. Why would it find the EAR without scoping, but not find it when scoping is enabled, since scoping does not affect modules inside the EAR file.
scoping:<loader-repository>foobar:archive=foobar.ear
exception: java.sql.SQLException: No suitable driver

[EJB/JBoss] - Re: jboss throws an exception when casting a proxy class
by jborra
Jaikiran,
First of all, thank you for your suggestion.
No, I do not have the bean interface in more than one jar (at least not in the files I have deployed). I have read the document for which you sent a link and also followed the suggested jmx-console steps to verify if the bean interface appears in multiple places. This is what I found:

>From the documentation and jmx's output I would say that I only have one instance of my test bean (ConfigurationBean).
I have more information but still do not know how to correct the problem. :(
Regards,
Jesus
