Re: [Wrapper-user] No GUI in entire System when running Wrapper as a Service

[<ro...@so...>]

Leif,
Sorry for the big delay...
But, NO, my Wrapper controlled JVM is a server application, which does not 
need even an user logged on.
I never needed to display any GUI in this application........
But once it is running, any other apps fail to start the GUIs via the 
command prompt........
And in fact, these apps hung in the show() or setVisible().

    Thanks,
    Rogerio.
