Hello,
I want to know when the JSP pages are compiled? When we save them or when they are accessed.
Actually, i created a JSP page and later i made some modification, but i am not getting the updated page in the browser. I think the automatically created servlet class is not getting updated.
Please help me out.

Although your JSP has errors which needs to be corrected. But the following line makes it confusing
The problem should be reported consistently by the container. Try clearing the tomcat cache. I think It should be at work/Catalina/
