i think if the jars are signed with different keys,the specified exception gets thrown

@Subbu I have a similar kind of requirement. Have you got it working?

@Subbu Yes you made sense. I do not see this as problem because the lib’s for each application is inside the respective WEB-INF/lib. We have multiple applications in tomcat but jars do not conflict

We have a scenario where 2 applications are deployed on a single application server and the applications are use different versions of the same jar and run in the same JVM but their class loaders are different..Did i make sense?

Subbu, what do you mean by 2 different class loaders in same jvm ?
When server starts , there is a hierarchy in which jars/class files are loaded.
If you keep jars at 2 different locations, that would still cause the same problem

Will this issue arise even if the jars loaded in 2 different class loaders in the same JVM? I have a requirement where i need to make use of different version of the jars.
