--------------------------------------------------------------
I am trying to configure few datasources in my environment and getting below driver problem.

i have tried with *ojdbc6.jar file and ojdbc14.jar* file in the classpath. 

If i use ojdbc6.jar file i will get class not found exception like below with sealing violation ..etc where as if i use ojdbc14.jar file i will get class cast exception. Basically what i understood is it's driver mismatch or something but not able to identify where could be the problem. I have tried all the ways, from my side if anyone have any idea about this or any clue please suggest me. I can give you more clarity on the problem if required.

Few extra details :- 

java version - 1.6.0.20
Jboss version - 5.1
