Debug Pylons application through Eclipse
yanjost has it right, just wanted to add that you need to make sure you do not use the --reload option, this will prevent the debugger from properly attaching itself and cause your breakpoints not to work. Just a little thing I ran in to.
I have Eclipse setup with PyDev and love being able to debug my scripts/apps.  I've just started playing around with Pylons and was wondering if there is a way to start up the paster server through Eclipse so I can debug my webapp?
