Re: Need help with cvsclient API

Ok, I hate to tell you this, but it's REALLY hard to get this kind of 
meta-information out of CVS. I've been working on the same thing, and in the 
end I gave up on it.

There is one clever workaround I know of: You can use the CVS history 
command so scan around for entries indicating the existence of this or that 
module. It's awkward though.

My solution, in the end, was to separately store that meta information in a 
database, and query the database with SOAP.

================================

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.

Console output:

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.
