[Json-rpc-java] CallableReferences

[Cosio, Dan]

What the servlet recieves in request:
{"id": 2, "method": "EbayService.runCSReport", "params": ["{ \"javaClass\":\"com.opsec.gnetadmin.dto.ebayadmin.CSReportBean\",\"timeFrame\":\"All\"}"]}

method resolution in JSONBridge
public java.util.List com.opsec.gnetadmin.service.EbayAdminService.runCSReport(com.opsec.gnetadmin.dto.ebayadmin.CSReportBean)

In the JSONSerializer
public Object unmarshall(SerializerState state, Class clazz, Object json)
	throws UnmarshallException
    {
	/* If we have a JSON object class hint that is a sub class of the
	   signature 'clazz', then override 'clazz' with the hint class. */
	if(clazz != null &&
	   json instanceof JSONObject &&  <<<<<<<<<<<<<<<<<<<<<<<<<<<<Fails on this test From my debugger json={ "javaClass":"com.opsec.gnetadmin.dto.ebayadmin.CSReportBean","timeFrame":"All"}
	   ((JSONObject)json).has("javaClass") &&
	   clazz.isAssignableFrom(getClassFromHint(json)))
	    clazz = getClassFromHint(json);

The above block doesn't return true because "json instanceof JSONObject" is false.. So, does my bean have to extend a JSONObject?

This is my bean
-----------------------------------------------
package com.opsec.gnetadmin.dto;

import java.io.Serializable;
public class CSReportBean implements Serializable
{
			
private String timeFrame;
			
  public String getTimeFrame()
  {
	return timeFrame;
  }

			
   public void setTimeFrame(String timeFrame)
   {
	this.timeFrame = timeFrame;
   }
}

Guys, how are you?
This mail is intended to contact you about the CallableReferences and how to pass them to a method declared in a bridge. I have made some changes in order to get access to an object regitered as remote. In my case I have made some test and by now I don't get any troubbles and all is working ok. This are my changes:

In JSONRPCBridge:
first I must to create a new method for lookupObject in order to get an Object in objectMap by the objectKey:
    //Added by elmasse
    public Object lookupObject(Integer key)
    throws Exception
    {
    synchronized (objectMap) {
        ObjectInstance oi = (ObjectInstance)objectMap.get(key);
        if(oi != null) return oi.o;
    }
    return null;
    }

In ReferenceSerializer:
allow to unmarshall to get an Object previously register as CallableReference
    public Object unmarshall(SerializerState state, Class clazz, Object o)
    throws UnmarshallException
    {
    JSONObject jso = (JSONObject)o;
    Object ref = null;
    String json_type = jso.getString("JSONRPCType");
    int object_id = jso.getInt("objectID");
    if(json_type != null && json_type.equals("Reference")) {
        synchronized (bridge.referenceMap) {
        ref = bridge.referenceMap.get(new Integer(object_id));
        }
    }//Added by elmasse
    else if(json_type != null && json_type.equals("CallableReference")){
            try {
                ref = bridge.lookupObject(new Integer(object_id));
            } catch (Exception e) {
                throw new UnmarshallException("Error while unmarshall CallableReference");
            }
    }
    return ref;
    }


I think that's all!
I'll be waiting  for comments!!!
Regards!
elmasse!

PS: Sorry for my english, it isn't very well! :-(
