Serializing Hash of Hash using .NET client to consume JAVa web service

Hi All,

I am really in trouble and for a long time now. My problem is like this: I have a JAVA webservice and I am writing a .NET client to consume the web service. I can consume the webservice that accept normal hashtables (by normal I mean hashtable containing key-value pair as normal strings), but the moment I try to pass a hashtable that has key as string and a value as another hashtable I get error like below:

Request message:

First key in xmlhashFirst value in xmlhashinnerhashkey in innerhashvalue in innerhash

Response message:

The problem is that the JAVA side is using Axis and the format of the hashtable it is expecting is as follows:

First key in xmlhashFirst value in xmlhashinnerhashkey in innerhashvalue in innerhash

The above request is generated by a JAVA client to consume the same web service.

The wsdl for the service is as follows:

Anyhelp would be a greatly appritiated.
