Question

After reinstalling Jetty i have problem with posting data by JQuery library. When i trying to post data with $.post function server returns 500 internal error. In jetty logs i have error like this:

I have tried to add libraries with that class to my project (and jetty/lib/ext folder), but errors appears again. Maybe i need correct version? What means this error? No method with correct parameters decodeTo(InputStream, MultiMap, String, Integer (??? I means Integer?). So any help will be apprishiated.

Looks like there was a problem with libraries in jetty/lib directories. We copied it from previous installation (long time ago we uses Glassfish). Now problem solved - i download jetty hightitude v.6.1 (from here: http://dist.codehaus.org/jetty/jetty-hightide-6.1/ ) (like my own jetty version) and just replace lib folder from it. I think problem was on jsp library.
