Any way of connecting a MAT standalone client to a remote MAT headless instance [message #921239]

My use case is. Huge memory dump, memory footprint of process is 21G, with resultant hprof file 32G. The process is running on a 64bit linux headless server.

I run the MAT tool in headless mode on my linux server to produce the various index files:

./ParseHeapDump.sh ~/software/logs/dumps/java_pid4301.hprof org.eclipse.mat.api:suspects org.eclipse.mat.api:top_components > /tmp/ParseHeapDump.log 2>&1 &

This produces an extra 34G of index files.

I am then copying the 32G dump file and the 34Gs of indexes onto my local Windows XP PC. And I then run the MAT standalone GUI to analyze the tool.

What I want to be able to do is not have to copy the files to my windows Xp PC (which is puny and has limited memory and disk space) and run the MAT standalone client on my Windows XP PC and connect to another MAT process running on my powerful linux server?

Is this possible? If not has anyone considered changing MAT to support this?

Currently there is no functionality inside MAT itself to achieve this.

However, I think that if you have some X Server tools installed on your Win box it should be possible to run any GUI program on your server (given that it has the neccessary GUI packages) and have the display exported to your Win box.

A different approach that was attempted was to enable MAT to be used as RAP application. In this scenario MAT is running in a web server (Jetty, Tomcat) and you access it via a browser. There was a prototype working, and a very nice contibution (https://bugs.eclipse.org/bugs/show_bug.cgi?id=262603) from Benjamin Muskalla about this, but I still haven't managed to integrate everything and produce "RAP-flavored" MAT.
