The question is in the title : \"Is there an equivalent to java @SuppressWarnings in JSP ?\"
If you are getting warnings in the code generated from a JSP (or in in-line code in a JSP), one solution is to move the problem code into a Servlet or into a utility class. That way you can mark it up to your heart's content, and your JSP has less Java code in it. Win-win!
I don't believe so, in fact i believe annotations cannot be used within a JSP file. You'll have you use the try / catch and handle your exception.
Yes, just use:
<%! @SuppressWarnings("unchecked") %>
