Re: intallation problem in argouml

Hello H.Santhosha,

I think you're using the GNU compiler for Java and associated VM, right? 
See the FAQ (http://argouml.tigris.org/faqs/users.html#linux_gcj):

Please install and use the Sun Java VM from 
http://www.java.com/en/download/index.jsp for Linux to run ArgoUML.
