Ext.Ajax issue With Serlvets 3.0 API

[bbehling]

Hello. I am using Tomcat 7 with Servlets API 3.0. When I make a request using the Ext.Ajax.request class, the request is never sent to the server and a "Comminucation Failure" error is thrown. I know this request never reaches the server because the Eclipse debugger never hits breakpoints.

I can use a call to the same servlet within a Form.Submit method, and that works - it hits the break points inside Eclipse. When I try to call the same Servlet in the Ext.Ajax class, it does not hit the server.

If I make a request to a PHP script, the Ext.Ajax class works fine.

Is this a bug with 3.x and Servlets 3.0? Or is there something I'm missing here?

Thanks for any ideas on how to fix this.

This works fine:

if(UploadControls.formPanel.getForm().isValid()){


            UploadControls.formPanel.getForm().submit({


                url:"http://localhost:8080/fade_servlets/GetProjects",
                waitMsg: 'Uploading file...',


                success: function(form, action){
                    UploadControls_Handlers.FormPanel_sucess(form, action);
                },
                failure: function(form, action){
                    UploadControls_Handlers.FormPanel_failure(form, action);
                }
            });
        }

This does not:

var getProjectsRequest = Ext.Ajax.request({
            url: "http://localhost:8080/fade_servlets/GetProjects",
            method: "POST",
            params:{
                username: "behlingb"
            },
            success:function(result, request){
            
                HeaderControls_Handlers.GetProjectRequest_success(result, request);


            },
            failure:function(result, request){
                HeaderControls_Handlers.GetProjectRequest_failure(result, request);
            }
        })

Seems to be a problem with cross domain Ajax requests. Too bad JSONP is not included in 3.x

I'll have to take care of this with a server-side proxy.

Looks like you might have the wrong forums - this is for Sencha GXT. Is there another forum that it would make sense for me to move this to?

Yeah, this doesnt belong on this forum. Sorry, thought this was the ExtJS forum.
