In the tomcat bin directory where<code>catalina.bat</code> or <code>.sh</code> is found (aka {CATALINA_BASE}/bin), edit (create if not there):

<pre><code>setenv.bat/.sh

Add the following line:

<pre><code>CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

That's all you need to do, you don't need to edit the <code>catalina.bat</code> (or <code>.sh</code>) file.

See the comments in <code>catalina.bat</code>or <code>catalina.sh</code>.

You may have to adjust the syntax for your particular environment/situation. For example, if you already have CATALINA_OPTS defined, you might do something like this (in a windows environment):

<pre><code>set CATALINA_OPTS=%CATALINA_OPTS% -Xdebug -Xrunjdwp:transport=dt_socket,address=8088,server=y,suspend=n
</code></pre>

To debug from Eclipse:

run->Debug configurations...->Remote Java Application->New

and specify a name, the project you are debugging, and the tomcat host and debug port specified above.

Let me share the simple way to enable the remote debugging mode in tomcat7 with eclipse (Windows). 

Step 1: open bin/startup.bat file 
Step 2: add the below lines for debugging with JDPA option (it should starting line of the file ) 

<pre><code> set JPDA_ADDRESS=8000 
 set JPDA_TRANSPORT=dt_socket 
</code></pre>

Step 3: in the same file .. go to end of the file modify this line - 

<pre><code> call "%EXECUTABLE%" jpda start %CMD_LINE_ARGS% 
 instead of line 
 call "%EXECUTABLE%" start %CMD_LINE_ARGS% 
</code></pre>

step 4: then just run bin>startup.bat
 (so now your tomcat server ran in remote mode with port 8000). 

step 5: after that lets connect your source project by eclipse IDE with remote client. 

step6: In the Eclipse IDE go to "debug Configuration" 

step7:click "remote java application" and on that click "New" 

step8. in the "connect" tab set the parameter value 

<pre><code> project= your source project 
 connection Type: standard (socket attached) 
 host: localhost 
 port:8000 
</code></pre>

step9: click apply and debug. 

so finally your eclipse remote client is connected with the running tomcat server (debug mode). 

Hope this approach might be help you. 

Regards..

Ii implies that you can setup JPDA with:

<pre><code>export JPDA_TRANSPORT=dt_socket
export JPDA_ADDRESS=8000
export JPDA_SUSPEND=n
</code></pre>

Or with:

<pre><code>JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"

And finally use:

<code>catalina.sh jpda start</code>
