Getting java.lang.ClassNotFoundException even though jar is there in WEB-INF/lib

Hi,

We have two applications with two wars deploying on JBoss 7.1.1 in cluster mode. War files are getting deployed successfully we are able to access one application with out any issues but in this application while accessing few components we are getting ClassNotFoundException even though the related jar file exists in WEB-INF/lib folder.

We tried the below options suggested in this forum. In all these cases we are getting same exception.

1. added the jar in the same module and added an entry in module.xml as a resource-root. (this did not work)

2. created a separate sub module by putting this jar and added that sub module by exporting the required packages in main module.xml as well as in jboss-deployment-structure.xml separately. (did not work)

3. tried adding a ClassPath or Deployments entry for this jar in MANIFEST.MF of META-INF(did not work)

4. We tried with Global modules option also.

NOTE: this issue is specifically observed in cluster mode only but the same configuration is working on standalone mode perfectly.

log is attached here with the exceptions.
