Subject BSF (Bean Scripting Framework) and Cocoon's usage of it ?? (Re: Seeking help on BSF calling a non-Java language engine (Rexx) ...
Date Wed, 11 Sep 2002 12:54:56 GMT
Hi there,

a couple of days ago I posted a question regarding the Bean Scripting 
Framework's (BSF) usage of Cocoon. BSF allows Java programs to invoke 
functions/scripts/programs written in non-Java languages and
in an IBM alphawork project. In the past months a process has taken 
place to hand it over to Apache.

The problem: using BSF to add functions to XSLT works nicely with the 
JavaScriptEngine of BSF, but does not work yet, if using the
(either with the open source Regina Rexx interpreter or IBM's Object 
Rexx, which is free for Linux, BTW).

The reason: "Cocoon" uses the call()-method and supplies the name of
function (as defined in the appropriate XSLT document) and the
but not the source code, containing the Rexx code to be executed.

Short of any other documentation, there is no way at the moment to 
determine the location of the source code (in this case embedded in a 
CDATA-section in the XSLT-file).

Hence the plea for help: where is the source code stored, how can one 
retrieve the source-code at run-time?

Any help or any hint is highly appreciated!
