DWR / JQuery and Tapestry 5.1

Hi,

I am interested in using either JQuery / DWR for some reverse AJAX in a Tapestry 5.1 web application, I would like to know if:
1) DWR can be integrated with Tapestry (if so, how?)
2) Is JQuery available in 5.1? are there Tapestry docs?
3) How does Prototype fair when using reverse AJAX?

Essentially I am looking for the best approach, as I still know very little about reverse AJAX, so any pointers or tips (tutorials for reverse AJAX with Tapestry!) are not just welcome but coveted.

Thanks,
Peter

I downloaded the latest snapshot version and deployed the jar in my local Maven repository... don't know if its working but its no longer complaining at least.

All you need to do is to tell Tapestry to not handle the DWR servlet
URLs, something you have already done by onw.

Are you sure you added the DWR jar/jars to the classpath? It seems
obvious, but the stack trace doesn't mention Tapestry, so it shoudn't
be the problem here.

No it wouldn't be, but Tapestry is a filter, and this is a Servlet, so the question is can they work side by side?

I can't see how Tapestry would cause a class not found exception, so I
guess this is not a Tapestry issue. Could you post the stack trace
here?

Thanks Thiago, but I think its going to take a little more than that to get it to work, I have tried the instructions here:
http://directwebremoting.org/dwr/reverse-ajax/getting-started
and have set the ignored paths but still get a class not found exception, does anybody know how to get DWR and Tapestry to play nice?

Peter

Tapestry's JavaScript code is written in Prototype, but that doesn't
prevent you from using any other JS framework.

I don't know.
