Subject Re: different versions of jars within EAR/WAR/EJB module
Date Sun, 21 Feb 2010 19:35:57 GMT
"jar hell" is the word XD.

We use an application called lady4j to solve this kind of issues because 
there is no general solution (AFAIK) to the class loading problems.

Drop your exceptions in lady4j.com and let it get the problem solved, 
(sometimes) it works XD.

For sure the openejb creators could help you better.

Regards.
