Hi Friends, I'm working with struts and successfully could run some egs. But for one specific eg when I changed the form beans, application is not working and giving me the exception.The struts.jar file is in lib directory.

Hi Mahesh, it's difficult starting to learn struts for everyone, but it's also difficult trying to work out what you might be doing wrong, so I'm going to ask a bunch of questions you might think stupid: you say you had struts working already - do any of the other examples still work? If so, then you are right, struts.jar is in the right place (if you're using tomcat, it's /tomcat/webapps/my_app/WEB-INF/lib ) where my_app is the directory name of the example application you are working with. What developer environment do you have?
I have seen things you people would not believe, attack ships on fire off the shoulder of Orion, c-beams sparkling in the dark near the Tennhauser Gate. All these moments will be lost in time, like tears in the rain.
