How to start Tomcat in debug mode for remote debugging

You have to set the JPDA_TRANSPORT and JPDA_ADDRESS environment variables. For example (on windows)

set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=9999

Then, start Tomcat.

Make sure you have selected socket transport from IDEA and that you are using the same port as you specified above.

Hi Saumendra,
Just create the following jpda_startup.bat file:

SET JAVA_HOME= SET JAVA_OPTS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_sock et,server=y,suspend=n,address=5050 call startup.bat -- Best regards, Eugene Zhuravlev JetBrains, Inc, http://www.intellij.com "Develop with pleasure!" "James" ]]> wrote in message

Well I don't want to start Tomcat from within IDEA cause I have had tried
alot with
the latest builds and had discussions with Eugene Zhuravlev and I have
failed. Check the thread

Anyways, I guess the best way to debug a servlet in Tomcat
through IntelliJ IDEA is by using remote debugging process.

Can someone tell me how I can start Tomcat for remote debuging ?
I know if I want to start my server and connect to my debugger in my IDE
using shared memory, I can use the following parameter
-Xdebug -Xrunjdwp:transport=dt_shmem,server=y,address=mydebug
and attach the name "mydebug" to IDEA's debugger

>

And if I want to connect via socket I can use this parameter
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=12345
and attach the port "12345" to IDEA's debugger

>

But I don't know where to place the "-Xdebug -Xrunjdwp:transport..."
parameter in Tomcat.

>

Do I have to edit any file and place this parameter, or do I provide this
parameter from command prompt. Can someone help. Providing an example will
be helpful.

Thanks

I issue the following:

./catalina.sh jpda start

This will start TC using JPDA with listening on port 8000.

I believe this should work similarly on win32.
