Exactly. I'm coding it right now - looks like CompileContext is enough - I'll post when I finish of course. > > I'm sure you see the similarity to .JSP now. > if my interpretation is correct, yes (o: > > > While it may seem basic, having API for this wouldn't hurt. > > Possible scenario: > > Supponse, there's some kind of mail server with *extremely* complicated > > rule-set in form of 200kb+ xml.

Generating source is out of scope of this project. I need it mainly for the complicated configs etc - no point in generating structure out of xml which is then analyzed everytime when you can compile it into bytecode. I'm sure it's possible to do xml-config to java-source transformation in xsl, but I don't like it personally, so I'll leave it to someone else. > cheers > dim Greetings, deacon Marcus ~~~~~ HELP STARVING JAVA PROGRAMMER: If you need cheap and reliable JSP hosting, please contact [EMAIL PROTECTED] (from 12$/m for 50mb WWW + 20mb mail)
