Message:

you are executing the class incorrectly....

Posted by Jeff Kinsey on September 04, 2000 at 9:36 AM

when you try to run "c:\com\sss\frm>java Slate", your java runtime environment thinks you are trying to invoke the class "Slate.class" instead of "com.sss.frm.Slate.class".

If you run:
java com.sss.frm.Slate
your class should run.
