Question
How to debug web application using Tomcat and Eclipse
Hi, there!
I am using Tomcat as webserver, and I am using spring MVC and hibernate build web applications. My IDE is Eclipse. Does someone could point me to how to make my controller called in debug mode? As far as I know, 1) I need to start Tomcat server with right optional parameters, i.e. debug port. But I do not know what I shall add, where in bat(catalina.bat) file I shall add. 2) In Eclispe debug option, I create remote debug, and set port to the optional debug port when I start the webserver.

Is this any use?

Not directly answering your question, I imagine that after a while debugging like that you'll get tired. Why not try a more integrated solution ? Eclipse 3.3 (Europa) with Webtools already has a tomcat starter that you can just run in debug mode with one mouse click and it will stop at your breakpoints.

For mindwalkr:
Thanks for your suggestions. Webtool is not my intension since I might need to migrate the application to weblogic. And at this moment, I have no experience about webtool. I do not know how does it go with weblogic.
For TimYates:
Sorry I did not check doc carefully. This link also tells how to config tomcat in debug mode. It is an article above remote debug link. If it works, I will give you 500 points.
For mindwalkr:
I will give you 50 points for this new tool information. But if you do not mind, could you please tell me how webtool works with weblogic? I could open another question for it and find my questions.
Don't worry about points if my posts don't help... I'm more here to try and help (and learn along the way) than for points :-)

Seems to say that to start it off running in debug mode, you need to configure two variables and call
catalina jpda start
Then you should be able to connect eclipse to it...
I followed following instruction: But I still get "Failed to connect to remote VM. connection refused."
"The short answer is to add the following options when the JVM is started:
-Xdebug -Xrunjdwp:transport=dt_soc
There are a number of ways you can do this depending on how you normally start Tomcat:
Set environment variables JPDA_ADDRESS=8000 and JPDA_TRANSPORT=dt_socket and then start tomcat using catalina jpda start."

don't you just start tomcat with:
catalina.sh jpda
And it uses port 8000 by default?
