hi Kiran,
Thanks for your response. I run the ApacheDS 1.5.7.
and just enabled the StoredProcedureExtendedOperationHandler in the
server.xml. Now a different Exception appears (see below).
I assume this has to do with the way I give the parameter processName
to JavaStoredProcUtils.callStoredProcedure()?
But what's wrong with Utilities.class.getName() + ".storedProc"; ?

Thanks once again
Simone
