I have been developing on Weblogic. Our app has many jsp's, struts controller servlet, over 20 javabeans, and a bunch of stored procedures. I inherited much of the code from the Rev 1 team and have been taking it apart to learn how it works. One thing I found to be incredibly usefull was hooking a debugger to the VM used to launch weblogic and setting breakpoints in the beans so I could step through code. The debugger I am using was low-cost and works great. (www.javix.com) The trick is to modify the startWeblogic script to launch the VM in debug mode. Then the main class, weblogic.Server, is specified in the debugger. Breakpoints can be set in the struts controller or wherever else. Then, browser requests made trigger the break. The other cool thing is javix is a lite little tool. Thus, there isn't a huge memory footprint like an IDE would make. What I would really like to see is a lite JSP debugger. I downloaded something from DAY.com, but it is unsupported and rev 1.0. It is supposed to allow me to debug jsp source. Additionally, a tool to handcraft and send HTTP requests without timing out would be neat. Does anyone have any tips on JSP debugging tools? I am cross posting this to the JSP forum as well.
