Regarding this problem in general...  I was unable to get Cocoon to
make an SQL request using JConnect (Sybase JDBC).  There's an issue in
the way the connection setup is attempted.  However I use this JDBC
driver in servlets all the time, so I just made a servlet output an
XML document (be sure to set the content type) and included the URL
for that servlet, with parameters, in my XML file.  It's working
perfectly.

We use Sybase with JConnect in combination with C1 + C2 - no problems here
