Hi All,

Am totally new to GXT. I was trying a simple application to display a FormPanel. But when I compiled the source its giving the following error. Can anyone help me please?

Am using GWT 1.5 and GXT 1.0.2.

add -Xmx512M to the java runtime - it will need more memory than default

Thanks for your reply.
I tried setting JAVA_OPTS to -Xmx512M.
But still its giving the same error.
Do I need to set any other variable?

where you set this depends on how the Java runtime is starting - is this a script or what?

Nope. Its an environment variable.
Where else you want me to set the memory to 512M?

It is not always an environment variable. In any case, my question was how are you running the Java runtime - via a script, command line, part of Eclipse IDE ??? /:)

Running out of VM memory is a known and common problem in GWT - the solution is to set the -Xmx512M VM argument to ensure the VM has enough memory.

If this is not working, then I can only suggest you are setting it in the wrong place :s

Good luck... :D
