Setting Maximum Heap Size Without Command Line

This is my first time posting so I'm sorry If I get this wrong...

I am trying to install "Sun Java(TM) Studio Enterprise" which worked fine at home but at work I'm always getting java.lang.OutOfMemoryException.

Using jconsole I can see that it sets the max Heap size to 66.7Mb which is used up when it starts decompressing jar files.

As the installation application is an exe I need a way to set the JVM Max Heap size without having access to the command line. ie. a way to set the -Xmx500m option (but not on the command line)

A bit of info... I'm running Windows XP with 1GB ram & 10GB HD spare.

It can't be done in the VM.You would have to do it externally such as creating an installer or creating your own wrapper that starts the VM.

Well thats a pain, and a bit daft aswell! I was wondering if it could be something to do with me running a Virtual Machine (not the JVM) because I've managed to install it on 2 other non VM machines... oh well thatnks for the reply.

If this application has an exe laucher - look in the manual for the launcher if it has a syntax to accept and pass on VM arguments (like eclipse does).

If you can launch this application using command line

(java -jar Application.jar or java package.of.Application)

Thanks for your help but i allready looked for this... The installed application allows this kind of command line option but not the exe installer... I've allready given up on this anyway...
