HOW TO DEBUG JSP PAGE?

Two ways:
1. If you don't have an IDE, add some <%System.out.println();%>.
2. If you have an IDE.
In Tomcat, the system compiles jsp into $tomcat_home$/work/your_project directory. Including this directory into your IDE source directory. Then, you can set breakpoint in your IDE.

[William Brogden]

1. Design your system to use helper classes such as JavaBeans that you can test separately from the JSP environment. Write a utility to test that bean with a variety of conditions.
2. Download my chapter on debugging servlets and JSP from web page for my Servlets and JSP book

I have done JSP development on Apache. I generally jump in to servlet which has been generated if I cant figure out bug in JSP.

The following plugin for eclipse allows you to step through the generated java code for a jsp, use breakpoints etc:

This type of thing is not usually required as print statements normally suffice. The other advice about separating the logic from the display elements is key.
