Custom web service

Hi ,

    I am new to ATG. I want to create a custom web service to update the shipping details in the order repository.I will get the request from external system.I want to update hardgoodshipping item descriptor based on orderId(which comes from the request). I need to give response to customer either success or failure (It is based  on reposiory update).

    I have created wsdl and xsd's to develop this service. I have to deploy this service on Jboss server and I used axis2 to develop server side from the wsdl. I have to create service implementation class in server side code to update the repository code.Now  I am unable to integrate my  implementation  code with ATG.

  What kind of configurations needs to be done to integrate wiht ATG. Wether I need to create a separate module in ATG or is there any way to create custom service in ATG. It is very urgent for me.

Please help ...........


Thanks in advance...

Geetha.
