Subject BSF - *any* knowledge at all in this group ? (Re: BSF (Bean Scripting Framework) and Cocoon's usage of it ?? (Re: Seeking help on BSF calling a non-Java language engine (Rexx) ...
Date Fri, 13 Sep 2002 10:49:39 GMT
Hi there,

so far I have not received one answer to the BSF-related question. As I really want to get
the Rexx
and Object Rexx BSF engines to work flawlessly with cocoon, I wonder what I could do from
this point
on.

Would the Xalan-group be more knowledgable/willing to help?

TIA,

---rony
