Hi Everybody,

I was able to solve my problem of serialization.
The solution is as follows:
I had to mark every member variable of my user-defined object "public".
Also I had to make a few modifications in my deployment descriptor. 
I got this info from
http://www.javaranch.com/journal/200603/WSComplexTypes.html


Now I'm facing a problem with deserializing the object on client side. 
My Object contains a 2D Array of objects of type java.lang.Object, 2 int
values and 1 String object.
While deserializing I'm getting the following error:

Caused by: org.xml.sax.SAXException: No object was found for class type
int

I'm attaching my server-config.wsdd and my client-side program.
Can anyone help me here?

Thanks,
Pratiksha
