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):
Linux: Why does ArgoUML fail to start with an exception in the GUI
components?
Many Linux distributions bundle GCJ (The GNU Compiler for the
Java™ Programming Language) which, as of April 2006, doesn't
provide sufficient functionality to run Java Swing applications
such as ArgoUML. You can check on the current status of GCJ at
http://gcc.gnu.org/java/status.html
Please install a supported Java run-time on your system.
Please install and use the Sun Java VM from
http://www.java.com/en/download/index.jsp for Linux to run ArgoUML.
Regards,
Luís
