Not ackd. As usual, the appropriate place to ask Xalan questions is on one of the *Xalan* team mailing lists, either [EMAIL PROTECTED] (where I'm forwarding this for you) or [EMAIL PROTECTED] Information about subscribing to these lists or viewing the archives is at http://xml.apache.org/mail.html Contacting individual developers is a Bad Idea, unless you happen to know them personally, especially when they haven't had enough coffee in the morning. ----- Forwarded by Shane Curcuru on 09/17/2002 08:53 AM ----- From: "Rony G. Flatscher" <[EMAIL PROTECTED]> To: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] Hi there, in the context of experimenting with XSL-extensions, implementing them with a non-Java-language, i.e. a self-developed RexxEngine (supporting IBM's Object Rexx on Linux, OS/2, Windows, and the opensource Rexx interpreter "Regina" on Linux and Windows), I had a student experiment with extensions. The problem: what works with JavaScript does not work with Rexx (the JavaScript extension example is enclosed, the JavaScript part should get replaced with a Rexx program as a proof of concept). The RexxEngine extends BSFEngineImpl, is loaded and call() is invoked. Unfortunately, the method call() does not receive the source-code (i.e. the Rexx code) but only the name of the function and the arguments. The question: how would one be able to get a hold of the source code at runtime? (Where is the program source of the script located?) Any hint would be highly appreciated! --- [With eval(), exec() and apply() all the arguments are more clearly defined compared to call(). Actually, I would have expected that apply() would be invoked instead of call(). call() is obviously meant for invoking a given method on a known object in the target scripting environment, hence my surprise that call() is used within the Xalan extension mechanism and not apply().] Also, please do not be offended, if I address all of you, who are known to be Xalan-implementors. It's just a sign of the high level of despair (due to strong time-restrictions and work-overload) and the hope that maybe one of you may be able to anwer this quickly and without too much effort. (The student, a non-Informatic student, has been trying for three months to solve the problem, I started two weeks ago to look into it and started out studying the e-mail archives of cocoon and posted questions there to no avail, now concentrating on Xalan, but have not found any information on this. The BSF-discussion list was not used yet, because its posting intensity is very low and I would not expect any help from there.) Thank you very much for *any* hint/help in advance ! Regards, Rony G.
