Error in launching rich client from Glassfish

          Hi!

I developed a Enterprice Application Client with one Frame to open and added it to my Enterprice Application.
I deploy to  GlassFish v2ur2 on Linux and when I launch the client from an url i get this error

java.lang.ClassNotFoundException: com.sun.enterprise.appclient.MainWithModuleSupport
