Should I nullify Object references in JSP's.
All my JSP pages uses a lots of String variables, should I nullify each one of them in the end of the page or are the objects automatically destroyed after the JSP page is executed.

Thanks

The Java code that you write in your JSP goes into the the service() method of the generated servlet. If you declare variables within <%%> block, they become local variables of service() method. So when the service() method completes (i.e., "jsp page is executed"), all local variables (i.e., local to service() ) will be destroyed.

If you declare variables in <%! %> block, they become instance variables of the generated servlet, so they will not be destroyed when the service() method completes execution.
