Using Eclipse debugger on a desktop to debug a Java app that accesses a MQSeries queue on a remote server

Hi,

I have a Java application that normally will run on a Solaris server.  When I try to use Eclipse locally to debug it, MQSeries cannot find the queue name because the queue is not local to my laptop.  When I run the Java application on the Solaris server, it does find the queue and processes the messages.

Is there any way for me to utilize the Eclipse debugger locally when the MQSeries queue is not local?

At this time the employees at this client have been using logger debug statements in the code and running it on the Solaris server.  This option is not nearly as powerful as the Eclipse debugger.

Greatly appreciate any help.

You can remote debug your application.
Your application runs on the solaris machine and you attach the eclipse debugger on your laptop to the vm running on solaris. Following some links that may help to set up this scenario:

http://help.eclipse.org/help21/index.jsp?topic=/org.eclipse.jdt.doc.user/concepts/cremdbug.htm

You normally have to start the JVM on your remote machine with options like:

java ... -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n ...

Details you can find here:

http://java.sun.com/j2se/1.3/docs/guide/jpda/conninv.html#Invocation

but for solaris details also look in your JVM docs and search for remote debug etc.

Here another link with options for 1.4.2:

Thanks,

This worked great.  One other point worth mentioning is that when using remote debugging, one must also ensure that the remote Java code was compiled with the debug option.  I had to alter the ant script to turn on debugging:

 <target name="compile" depends="prepare"
          description="Compiles all source code.">
    <javac srcdir="${src.dir}" destdir="${build.dir}"

debug="true" debuglevel="lines,vars,source" />

Otherwise, Eclipse was complaining about "attempting to install a breakpoint in type "myClass" that has no line numbers.
