Debug application server

[steve]

Any idea how to debug an application server; such as, tomcat or jboss?

Any hint or guide are welcome.

I have been working on simple Servlets and have found Caucho-Resin
just gets in the way of debugging. What a pain in the butt! You can't
place your source code in an easily accessible place. You can't
compile in your normal way. You get error messages on the browser
which don't take you back the corresponding source code, and the womb
keeps giving you the old code. You can't use any debugging tools.
Every compile-test cycle takes at least 5 times as long as it would
normally.


Further you work blind -- not seeing the traffic in and out in the
sockets to the client or to MySQL.


I think the way out, at least for Servlets, would be to write or find
an absolutely minimalist Servlet womb. You compile and run everything
in the traditional way. Once you get it all working, then you move it
to a full blown womb. Then when you get that working, you move to a
server.

Whereas I've been using Eclipse and have been very pleasantly surprised
by how transparent debugging has become. Creating breakpoints, setting
watches, etc., easy as pie. Sure beats printlns and following the logs
with "tail -f"...
