JRun and using a Java Debugger

[Steve]

Hi;

A company I am working for is using JRun 3 ( they have
plans for moving to JRun 4, but it is going to take a
while ).

I am using a multipurpose IDE called Visual Slickedit 9.0
that comes with a java debugger ( it looks like a front
end to the jdk that comes with the jsdk ).

I am having trouble attaching the debugger to the remote
jvm for a JRun webapp/site.

The directions (below) that come with Visual Slickedit call
for feeding the remote vm some special arguments and
restarting it.

I am going to the "java arguments" field in my web app and
inserting the following string ( adjusting for the port
of the web app):


-Xdebug -Xnoagent
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000

Once I do however, I can't get the webapp to restart.

Do I need to prepend "java" to the string above?

If not, what do I need to do to get the java debugger
and the JRun 3 web app talking to each other?

Thanks in advance for any insights or information.

( from the slickedit help section ):


Attaching to a Remote VM (Java Only)

To attach to a remote VM:

1. Start the remote VM with command arguments similar to the following:

Java -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,

suspend=y,address=8000 MainClass Arg1 Arg2

2. Choose Attach to Remote VM\u2026 from the Debug menu.

try suspend=n

I did, no luck, the jrun webapp would not restart

Strange, flags look correct. Also, JRun 3 SP1 has a -debug options that
does exactly the same. Check these links:
