I try to login to my web application sitting on a RHEL5, from my windows laptop. I got the following error message:

Java.Lang.OutOfMemory Error: Java heap Space

Please Advice

That's an issue with either your java app (could it be leaking memory?) or just that it actually requires more memory than what's available on your JVM.

If it's the later, you can adjust the heap size (on your windows client) passing the -Xms and -Xmx parameters to java.

Eg: "java -Xms128m -Xmx512m" would set an initial heap size of 128MB and maximum of 512MB for the JVM.

It could also be that the maximum heap size is configured to an unnecessarily high value on your tomcat server.
