Need help with cvsclient API

At the bottom of this message is my test app.  I am fumbling through the
API, and I may have some irrelevant code, and/or be missing some crucial
code.
 
What I am trying to do, up to this point, is to determine if there is a
module of the given name in the CVS repository. 
 
First I check the modules list, which for this sample is empty. This appears
to be working fine.
 
Next I want to determine if the user has a sandbox, and if not, create one
by checking out the CVSROOT directory from the repository.  No joy. The
checkout command instance throws a Command Exception, but the messages are
null.
 
Are there any pointers or places I could look for guidance?  I tried to look
at smartCVS, but it is obfuscated.

WARNING TO DEVELOPERS:

Please be warned that attempting to reuse one open connection for more
commands is not supported by cvs servers very well.

You are advised to open a new Connection each time.

If you still want to proceed, please do:
System.setProperty("javacvs.multiple_commands_warning", "false")

That will disable this message.
