> How do you integrate tapestry source step/debugging into eclipse?
You tell eclipse where the source to the jar is by attaching it in the build
properties dialog under libraries. You shoudl then be able to pull up any of
the tapestry classes in eclipse and see the source.
When I set a breakpoint on a source module, nothing happens. I am launching

Are you starting jetty with debug options turned on? Are you connecting to
it from the eclipse debugger?
It may be easier to grab the jetty plugin for eclipse and debug it that way.
There are lots of resources on the web for getting debugging in eclipse this
set up, although the first time around it's going to be a pain but in the
long run it will make you a more productive java developer.
