Error in Websphere_J2EE application

HI Experts,

I have a j2ee application running in WebSphere.Now i got an error in one of the pages(say attemptQuiz.jsp)
There is java installed in the server(in E drive). And i can see there is another java inside WebSphere(C:\Program Files\IBM\WebSphere\AppServer\java).The JAVA_Home environment variable is set to the java residing inside the E drive but the JAVA_HOME in WebSphere is set to ${WAS_INSTALL_ROOT}/java

My assumption is that the E drive java has got upgraded and it is used to compile the files and the lower version java inside the WebSphere is used to run the application.

Can you please help me in sorting out this issue

I am attaching the screen shot of my error with this post

Thanks in Advance

This issue can be resolved by replacing the class file of the corresponding j s p page at the corresponding location.

Or

By clearing the wstemp and temp folder of WebSphere and on restarting the server(means rebuilding ). it will be solved.
