Moving to JSP

[William Brogden]

My number one suggestion for debugging in JSP or servlets is to put all the working code in "helper" classes that can be tested and debugged OUTSIDE the servlet/jsp environment.

There are so many things that can go wrong when you plunk totally untested code into a jsp/servlet container that it is hard to conduct intelligent debugging. Just browsing through recent posts will convince you of that.

Is there a particulare IDE you are using?

With WebSphere Studio Application Developer, or IBM's Rational Application Developer (IRAD), you can set breakpoints in Java code in a JSP and step through your code at runtime. It's an invaluable service.

Having said that of course, there is great value in minimizing the amount of code in a JSP. Factore out logic into custom tags or Java classes which are easier to maintain, reuse, and debug.
