Solution needed for OutOfMemoryError: Java heap space

[Melinda Savoy]

I am working in Eclipse on a java program that I inherited and I am getting the following error when I'm trying to import an .XML file that is 57MB in size:

2009-09-21 09:56:34,781 INFO  GsaEplsVendorDB - Importing XML file "c:\gsa\report.xml".

My question: is there a way to increase the memory for this program to run by manipulating the VM arguments in Eclipse? I was thinking of putting the following in the VM arguments section of the Debug Configurations? I was thinking about inserting this into the VM arguments: "java -Xmx1024M" . I do have Program arguments as well.

Any help and/or direction would be greatly appreciated. Thanks.

Why not just try it?

How are you running the Java app? If in the same JVM as Eclipse, then making the eclipse.ini changes should work. If in a separate JVM, then you will have to provide the JVM options as part of the run configuration (VM Arguments list box on the Arguments tab).

Peter -- thanks. I finally got it running.

David -- Sorry, I should have mentioned that I had tried running it and kept getting an error. I just did not know if I put in the memory allocation setting in the VM Arguments or not and was looking for some help.

Thanks guys. I appreciate the time and help. Regards.
