Hi again.
I'm not too sure about the problem I had but I've tried with another web application server in a different OS environment and it worked, so my problem is now fixed. Regards

I was using Tomcat 6 and later I tried Glassfish 2.1 using my environment (VMWare Workstation 6.5.1 running a Win XP virtual machine) and it didn't work. Then, I forwarded the war file to another workmate and he tried it in a Glassfish server with success using IE and Firefox.
Sorry I can't provide further information but if get to some conclusion I'll post it.
