I have Created number of JSP Applications with html code, in which if I make any changes on JSP (for eg I want to add one more button ) and run it , it will not Change(will not add new button) and retains the previous code and works. But if i save as the same file with some other name , it works properly(ie adds new button).

Can anyone say the reason ? and how to solve it? .

Number of JSP applications? what is that? are trying to say no.of jsp pages!

Which app server you are using? be little informative.

What kind of web container did you use? is Tomcat? Weblogic? or Jboss?

It shouldn't like that, jsp file will auto update when you do some changes. Ant the change occurs when you send a new request, web container will first see if the jsp should update, and then jsp will display on the browser.

So make sure your browser will send a new request to get the newer jsp, may be that is the problem
