Failed to load servlet

[Nilesh Pathare]

Hi,

I have deployed an application on Websphere Server ver. 5.1 and when I try to access the application I get an Internal Server Error. After checking the log file I could see the error below.... Can anybody help me explain whats going wrong with the application or the server.

Thanks in advance...

This can happen if you put your struts.jar file in a common area used by other applications. Make sure that the struts.jar file and its accompanying commons-xxx.jar files exist in the WEB-INF/lib directory, and nowhere else.

Thanks for the reply..

I check all the .jar files location and they do reside in the WEB-INF/lib folder only. Any other suggestion or something else I should be looking at ???
