Bruce and David:

I don't need to create a lib folder of my own and then set classpath to it.
I finally found out that I just have to put my jar into %babeldoc_home%/lib
directory.  The problem that babeldoc did not find my jar before is
because the way that script imports the classes.  Now, I fixed the scripts
and the babeldoc finds my jar and starts validationg the file. It is very
good.

However, another problem.  In my validation routine, I use Velocity to
generate a validation report. Now, for some unknown reasons, my Velocity
could not start.  See the following error trace.  I put my debug statement
in my validation routine.  The problem is right at initializing the
VelocityEngine.   I checked the Velocity documents, there are two ways to
initialize the Velocity: Singleton and non-Singleton.  Singleton means only
one instance of Velocity per JVM allowed.  I guess when I tried to
initialize my velocity, the scripting does not like it.

Is there a reason that the babeldoc only allows Singleton Velocity?  Can we
change it to none-singleton?  Where is in Babeldoc that Velocity is first
initialized?  Maybe I can try to change it to none-singleton and see if it
makes any diffrerence.

Please let me know,  I am pretty close to get this thing work. The only
thing that needs to fix is the initialize the velocity.

Thank you.

You need to import your class into the javascript.  Please read the
documentation found at the Mozilla/Rhino/JS site (use google to find the
URL).
