You're right. Trying this yields:

TypeError - Value undefined (result of expression jason.wopage.application().terminate) is not object.

You need to get a servlet.jar and add it to your /Library/ WebObjects/Extensions.

And you should be careful with that component. I haven't yet tested it, but it seems to me that if you bind up your page as the proxy object, you could call sth like page.application().terminate ()...

I didn't try, but from reading the code, my understanding is that you only get 1 level interface from the proxy object. So if the page is your proxy, the rpc will make public only the method availlable from that page object. So yes you can call page.application(), but the rpc will receive an application object which is a big 'undefined' in javascript. You then won't be able to call 'terminate()' on it since this will be evaluated in javascript (a no opp).
There is a way to return another proxy object, this is an 'advanced' feature of json-rpc (foreign reference or something like that), but this is not yet investigated for wo integration.

Hi Mike,

Thanks for all your hard work. The sortable list is something that I have been in desperate need of for my application, and to see it implemented is just too cool. The drag and drop shows promise for inclusion soon too...

The RPC link still doesn't work, at least on my system. I am using build 67 and received the following error for the first hyperlink (the rest work perfectly):

OK, the build script is fixed up ... Wonder build 67 includes AjaxExample.woa in the Wonder-2.0.0.67-Examples.tar.gz (rather than the Applications tar). You need Ajax.framework and ERJars.framework in your /Library/Frameworks folder to run it, and those are in the Frameworks tar. Third time's a charm :)

I only run it in Eclipse, so I didn't notice that it didn't have the real framework dependencies setup, only the eclipse project dependencies (which also explains why i couldn't get the build script working properly most likely). I replaced that AjaxExamples tar with the PROPER one (really only differs in that the classpath files are updated). Your process was correct.
