You just need examples of java using rhino. I was recommending changing to regular java xsp. You'll need to use <xsp:structure> and <xsp:include> to make sure the rhino classes you need are available in your xsp and then later on in <xsp:logic> you can do anything you would in a normal java class (because when cocoon is done with your xsp file, it _will_ be a normal java class. If you haven't gone to look for the .java source files that cocoon generates out of your xsp (probably under tomcat's work/ directory) you really should. It would take some of the mystery out of xsp. Rhino is a javascript interpreter/engine (whatever). So within your xsp now written in java, you'll retrieve your html page, pass on any regular tags, and then pass the contents of the script tags to the rhino instance. To be very clear: I have no idea if this is feasible and if you're not very comfortable in java, the chances are slim you'll get this working without more help than I or probably anyone else on the list can provide. I'm just suggesting an avenue to try. > Can you give me an > example, or a URL to the page with example? I am > sorry, but I tried hard to > find examples, and I just didn't succeed.

They do - what they're talking about is xsp-js though. I'm suggesting you abandon xsp-js because of some of the other things you need to do, and call the same java-based javascript interpreter directly from your java class (which xsp just helps you create.) > 2. Can I use JSGenerator instead of > ServerPagesGenerator on the pipeline? That's happening automatically when you declare that your xsp's are written in javascript. But you probably don't want to do that anymore. The only reason you ever needed xsp-js was because it gave you access to the Rhino javscript stuff behind the scenes. But it took away your ability to use the java stuff you need. > > All these things confuse me alot, and I'll be very > happy if you gave me some > more clues. > Thank you very very much and sorry for attacking you > with so many questions. > > Anna I can appreciate how confusing this must all seem to someone new to cocoon, and even worse if you're new to java - I'm sure all this just seems like absolute voodoo. Unfortunately, all I can give is clues because my own time is limited and because you're trying something fairly novel. Best of luck, Geoff PS, it's a holiday later this week in the states, so I may be off list for a while. > > ----- Original Message ----- > From: "Geoff Howard" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, November 26, 2002 12:14 AM > Subject: Re: JavaScript problems in XSP > > > Ugh.
