Re: NoClassDefFoundError

That did the trick.  I needed the .jar in the classpath.  I just had the
directory not that acutal file listed.  Now I get an error saying

org.jawin.COMException: 800401f3: Invalid class string

This happens when it tries to declare the methods that were created from the
Typebrowser file.  If anyone knows what this is from that would be helpful.
I will play around with it tomorrow since I do not have time today.  I feel
guilty asking questions that I have not really looked into myself yet.
Thanks for the help so far Christophe and Morton.  You guys have gotten me a
lot further along.
