Question Are there any IDE's which will help me debug JSPs?
Derived from A question posed by John Zukowski PREMIUM

Answer
IBM's Visual Age for Java (VAJ) IDE provides numerous features to aid in the debugging and incremental development of JSPs. VAJ Professional and Enterprise Editions come with the JSP Execution Monitor, which allows you to simultaneously view the JSP source, the generated servlet source as well as the dynamically generated HTML content.

A really cool feature is that you can enable VAJ to work with the freely available JSP 1.1 reference implementation Tomcat, available from the Apache Group. In fact, you can also use the freely available VAJ Entry Level Edition (which is limited to using 750 classes - more than sufficient for getting started) to debug JSPs which run under Tomcat. Read the excellent article published in the Visual Age Developers Domain titled "Apache Tomcat Servlet and JavaServer Pages Development with VisualAge for Java" by Sheldon Wosnick for the inside scoop.

Oracle recently announced JDeveloper 3.0, which features wizards to aid in JSP development and debugging.

Inprise JBuilder claims to support JSP debugging but doesn't actually support placing breakpoints in the generated JSP source. Instead it has a built in JSP container that allows you to place breakpoints in associated beans, servlets, and classes that are used by the JSPs.

This is not a serious problem if you are doing "model 2" jsp development, with all your logic abstracted away from the presentation layer, but it can be annoying.

It is true that with VAJ, when using JSP execution monitor, you can simultaneously view the JSP source, the generated servlet source as well as the dynamically generated HTML content. Once you enable VAJ to work with Tomcat though, this feature is unavailable.

I found Forte for Java (Internet edition) very helpful in debugging servlets and JSPs. It gives almost all the features you might have seen in Microsoft DevSudio or Symantec Visual Cafe and does not force you to use any Forte-specific libraries. It launches Tomcat internally. Forte is relatively cheap compared to others. See http://www.sun.com/forte/ffj/buy.html
