How to debug Java Web Application in Netbeans?

Question

I have debug Java Desktop Applications various times in Netbeans but haven\'t debug Java Web Application ever.

I tried to debug it the same way, but it\'s not working.

Answer 1

How did you start your web application in debug mode? On my machine, I simply select the project, click on the Debug top menu, then Debug Project, select a Server (GlassFish, WebLogic, Tomcat) if required and things just work (I can place a breakpoint in a Servlet and the execution stops there). Tested with all the mentioned containers.

Also sometimes, I don't know why the project detaches itself from the debugger process, you just need to select the menu Debug -> Attach Debugger and attach the project again. For example in Glassfish just put localhost as the server and 9009 as the port and it will work again
