anyone know what this means thnx.

It seems it was know bug from release of NetBeans 6. Try to update your NetBeans to latest version 6.5 and see if you still getting this error

Thanks peter_budo for your reply, is there no way of getting this error fixed without installing NetBeans 6.5

Either upgrade or not using that method of the class and try to work around. Sorry.
