I have tried but I can't figure out how.
Is there a guide to remote debugging with tomcat 5.0?
You have to set a registry key (for Window anyway).

If I remember correctly here it is:
set JDPA_TRANSPORT=dt_socket
set JDPA_ADDRESS=5005
%CATALINA_HOME%\bin\catalina.bat jpda start
This must be the same as in IDEA Run/Debug Configurations => Remote
Hope this helps.

yep, I start tomcat with:

-Djava.endorsed.dirs="" -classpath ";..\bin\bootstrap.jar"
-Dcatalina.base=".." -Dcatalina.home=".." -Djava.io.tmpir="..\temp"
org.apache.catalina.startup.Bootstrap start
and just attach IDEA via remote debug tag on port 9999.
Works good, unfortunatly doesn't work for jsp2 but I can live with that.
And hotswap/reloading doesn't work properly .. tomcat sometimes starts
reloading the context (reloadable=true) while IDEA is still compiling
and tomcat complains about missing files.
EAP 1122, btw.

What if you turn off reloading? Does it work then? Presumably reloading
isn't necessary if you've got hotswap.

I'm using this setup since idea3.0.1 or something so I never really got
into hotswapping. To be honest I don't like hotswapping. But I tried it
yesterday and my guess is since idea is in a different vm than tomcat it
won't work. At least I get some "scheme not supported" error when trying
to hotswap.
I'm using the same debug settings with no luck. Intellij gets stuck at "Connecting..." when I try to debug. I've tried a few different ports incase there were conflicts. This is using tomcat 5.0 and java 1.4.2.

Ok, I restarted IDEA and it worked. I remember a bug where if the debugger failed to connect the first time you try it it will fail until a restart. I'm pretty sure a bug was submitted.
I have it working with .java. Why doesn't it work with .jsp?

Yes works fine for servlets, just start tomcat with catalina.sh jpda run (or start) and then attach to the port. Hotswap works fine.
Haven't been able to get Remote to work nicely with JSPs though.
My setup is tomcat on a solaris box, idea on my xp machine.
I haven't really tried reloading in Tomcat yet as I've mainly been working with
Weblogic. As we have a quite large application the reload will take quite a long
time. So when just one class is changed I like hotswap a lot better :)
The problem you experienced has nothing to do with IDEA being in a different VM.
It just means that the changes you did to your class is not supported by Hotswap
on the VM Tomcat runs under. That is, changes to a class' schema is not supported.
I think deleting methods is among the changes that would classify as changing a
class' schema.
I've done quite a lot of reloading classes and it works amazingly good even for
a web application with session objects, etc. As the project I'm on has Eclipse
as the default IDE I tried it there too, but then I got some error when trying
a reload. If I just had discovered that earlier...this would have made it easy
to convince the manager to by IDEA :)

To debug jsps you need to actually have your webapp running through Intellij, not just attached by a remote debugger. I don't know the details all that well, but from what I gather Intellij specifies it's own directory for the compiled jsps that it can then reference back to any breakpoints you add.
Webapp runner/debuggers can be set up under the "WebApp" tab in the "Run/Debug Configurations" screen.
It works partially for me. Remote classes (ie, not JSP) are fine, including servlets. I can set a breakpoint at a JSP and IDEA will stop at that, but then stepping doesn't works -- but resuming and expression evaluation still does, at least.
Ah, there's a little trick: I added the directory where tomcat (in fact, JBoss 3.2.3 + Tomcat 5.0.16) generates java source code as a source folder for my web module.
ditto. Running through IntelliJ allows limited debugging of JSPs. I was
kind of disappointed. No stepping and it is a pain in the arse to find your
data values. The data values may have more to do with jasper2, then
IntelliJ.

Hi, I think I know the issue here.
Add
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
to the Configure Tomcat java params.
do not put -Xnoagent this is the real culprit here
if you include -Xnoagent will recive error connection refused for ever .
Enjoy Happy development :)
