Zone Update with POST

[Torsten Weber <to...@gmail.com>]

Hello,

I am using an editor written in javascript. When someone clicks on "save"
data should be sent to Tapestry and a zone should be updated.

Currently in javascript I call:

    zoneManager.deferredZoneUpdate(zoneId, zoneUrlWithContent).

zoneUrlWithContent contains the content of the editor as parameter and I
retrieve the content in  Tapestry with:

    Object onSave(@RequestParameter(allowBlank=true, value="content") final
String content) { .. }



Now I want to send the content by POST because the size of URLs is limited
to 8192 characters.


Can you give me an example (JS and Tapestry event handler in Tapestry 5.4)?


Thanks in advance.
T.W.

For handling POST, I'd utilize Tynamo's tapestry-resteasy (
http://www.tynamo.org/tapestry-resteasy+guide/). JS could be something like
this:

$.ajax({
   url: 'http://my.server.com/editor/save',
   data: data,
   error: function() {
   },
   dataType: 'json',
   success: function(data) {
   },
   type: 'POST'});

JAX-WS EditorResourceImpl.java:

@Path("/editor")
public class EditorResourceImpl implements EditorResource {
    @Path("/save")
    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    @CommitAfter
    public Map<String, String> saveContents(EditorContents contents) {
        ...
    }
}
