Remote Debugging Java applications in Emacs


Emacs can quite comfortably do debugging of Java applications running on remote JVMs using the excellent JDIbug.

JDEE provides two other means to debug applications, but I would recommend JDIbug any day of the week. It's fast and provides a visual tree of variables. Currently (2009-07-18 13:06), it has one drawback; it cannot debug inner classes, but I'm sure this is something that will be remedied in a later release.

Given that you have the given source code in the jde-sourcepath variable, you can browse the call stack leading up to the break point. Here, I am browsing the state of one of Tomcat's classes when executing my test.jsp
