问题
I am working on application deployed in WAS 8.5.5.2. I am getting the below error while rendering TIF image. I have kept Axiom 1.2.14 which is latest in classpath and restarted the server. Got a classcast exception. Then, i have searched the entire WAS for any internal builtin jars and found few instances under org.apache.axis2 jar (builtin jar in WAS runtimes folder). SO i have removed my jar from the classpath. Still i am getting the same error. Any clues will really helpful ..

If you want to use Axis2 in WebSphere, you need to configure your application as described here.
