Hi All, I have a webservice written in APEX which returns a complex object. This complext object is a List of Object which itself has another list of object. we can say 2D arrays.

While i am trying to consume it from a Java client it throws this error: 

"Circular Object Graph detected during serialization, you can not have circular object references in an Apex WebService response."

My class is: 

global class SampleService
{
    global class  ObjectFieldInformation
    {
        WebService Integer fieldSerialNumber;
    }
	
    global class  ObjectInformation
    {
        WebService List<ObjectFieldInformation> objectFieldInformationList;
    }
   
    
    global class CallsResponse
    {
        WebService List<ObjectInformation> callList;
        WebService String something;
    }

    WebService static CallsResponse getComplexObjects()
    {
    	FindCallsResponse  response = new FindCallsResponse();
        
        List<ObjectInformation> responseCallList =  new List<ObjectInformation>();
        ObjectFieldInformation objResultFieldInfo;
        ObjectInformation objCallInfo = new ObjectInformation();
        
        for(Integer i=0;i<5;i++)
        {	
               	List<ObjectFieldInformation> callData = new List<ObjectFieldInformation>();
		        for(Integer j=0;j<5;j++)
		        {	
	        		objResultFieldInfo = new ObjectFieldInformation();
		                callData.add(objResultFieldInfo);
		    	}
		    	
	        objCallInfo.objectFieldInformationList = callData;
	        responseCallList.add(objCallInfo);
        }	
    	 response.callList = responseCallList;
    	 return response;
    }
}

Please advise.
