thank You for Your response. But I have still the trouble with  
convertion JSONObject to my Object:

The rcp request is:
{"service":"com.tietoenator.nas.common.ui.qooxdoo.RTOrder","method":"t 
esObj","id":2,"params":[{"$ 
$initialized":true,"classname":"com.tietoenator.nas.common.ui.qooxdoo. 
Result","name":"com.tietoenator.nas.common.ui.qooxdoo.Result","basenam 
e":"Result","constructor":[Class  
com.tietoenator.nas.common.ui.qooxdoo.Result],"message":"some  
text","ret":1}],"server_data":null}

my java object Result has defined default constructor, getters/setters
    

Then it should work. Could you send the source of your Result class  
(or at least a skeleton that shows all the constructor and method  
signatures)?

Regards,

   Andreas

Hi,

I found the bug at class net.sf.qooxdoo.rpc.RemoteCallUtils, method 
toJava(Object obj, Class targetType), line 136.

There isn;t check to null of desc variable. All works fine, if I add the 
test;

          --- added                if (desc != null) {
          --- line 137                 
PropertyUtils.setSimpleProperty(bean, name,
                               toJava(jsonObject.get(name), 
desc.getPropertyType()));
         --- added                  }

Could You fix it, please?


Here is the JS object which I'm sending trough RPC call:

qx.Class.define("vbz.Result",
{
 extend : Object,

 members :
 {
    ret: 232,
    str: 'some value'
   }
  
});

This is the request:

{"service":"vbz.RTOrder","method":"testObj","id":1,"params":[{"$$initialized":true,"ret":232,"str":"some 
value","classname":"vbz.Result","name":"vbz.Result","basename":"Result","constructor":[Class 
vbz.Result
]}],"server_data":null}

The property classname does not exist's at my javabean vbz.Result, the 
PropertyUtils.getPropertyDescriptor(bean, name); retuns null and the 
PropertyUtils.setSimpleProperty(bean, name, toJava(jsonObject.get(name), 
desc.getPropertyType())); try to invoke method getPropertyType() on null.
