I'm using POI jar file (POI Final version)in my web application in the same way some other file using POI beta version so there is an conflict between both the jar files if i remove beta version mine application will run so that other application uses beta version will throw exception.how to over come the conflict
What do you mean by "some other file using POI beta version" - some other web app? If so, then each web app should have its own POI version in its WEB-INF/lib folder, and they wouldn't conflict. Conflict can arise if you keep the POI jars in a shared directory.
