Sending form values json encoded to REST java webservice

[testvogel]

Hi all,

I'm new to Sencha Touch and want to build a simple form panel which will be send to a REST service which is implement with Java jersey. The webservice is working properly (tested with Soap UI) and also the sencha app is working fine until I'll press the submit button of the form and if I'm using the submit() function. If I use Ajax in the button handler, the webservice will be called properly, otherwise I get following exception at the webservice:

Caused by: java.lang.Error: Error: could not match input    at 
com.sun.jersey.json.impl.reader.JsonLexer.zzScanError(JsonLexer.java:491)
    at com.sun.jersey.json.impl.reader.JsonLexer.yylex(JsonLexer.java:736)

Sencha code:

{ 
                           text: 'Save',
                            ui: 'confirm',
                            handler: function() {
                                console.log('storing');
                                var form = Ext.getCmp('checkoutform');
                                console.log(Ext.JSON.encode(form.getValues()));
                                form.submit({
                                        url: 'http://localhost:8080/example/service/',
                                        method:'POST', 
                                        headers: {
                                            'Content-Type': 'application/json'
                                        },
                                        params: Ext.JSON.encode(form.getValues()),                                    
                                        success:function(form, result){
                                               console.log("succ");
                                         },
                                          failure:function(form, result){
                                            console.log("fail");
                                        }
                                });
                            }
                        }

If i use the following code the call of the webservice is working fine:

{
                            text: 'Save',
                            ui: 'confirm',
                            handler: function() {
                                console.log('storing');
                                var form = Ext.getCmp('checkoutform');
                                console.log(Ext.JSON.encode(form.getValues()));
                                Ext.Ajax.request({
                                        url: 'http://localhost:8080/example/service/',
                                        method:'POST', 
                                        headers: {
                                            'Content-Type': 'application/json'
                                        },
                                        params: Ext.JSON.encode(form.getValues()),
                                })
                            }
                        }

Does anyone have an idea why the form.submit function is sending anything but not properly json data?
btw. form.getValues() returns json data:

{"name":"","address":""}

The submit method is going to use form POST and encode the params using Ext.urlDecode.

If you need a more specialized way of submitting, you can use Ext.Ajax.request to do the submitting. In fact, jsonData will automatically encode the Object to JSON.

Hi,

I thought that

headers: {'Content-Type': 'application/json' }, 
 params: Ext.JSON.encode(form.getValues()),

would encode the url encoded form data to json encoded data.

Is it possible to change the encoding format of the form data or do I have to use Ext.Ajax.request instead?
