The question is in the title : "Is there an equivalent to java @SuppressWarnings in JSP ?"
262
Use of @SuppressWarnings is to suppress or ignore warnings coming from the compiler, i.e., the compiler will ignore warnings if any for that piece of code. 1. @SuppressWarnings("unchecked") public class Calculator { } - Here, it will ignore all unchecked warnings coming from that class.
@SuppressWarnings instruct the compiler to ignore or suppress, specified compiler warning in annotated element and all program elements inside that element. For example, if a class is annotated to suppress a particular warning, then a warning generated in a method inside that class will also be separated.
You can use the @SuppressWarnings("unchecked") which is supported by both the eclipse compiler and javac. But remember the @SuppressWarnings annotation is used by your compiler which can have its own values. The JLS only forces the compiler to understand the values "unchecked" and "deprecated" (for now).
Yes, just use:
<%! @SuppressWarnings("unchecked") %>
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!
