Java utility to connect and fetch data from on premise CRM

Hello,

We are trying to connect to on premise CRM. Initially, we tried to connect through the stubs OrganizationServiceStub.java which was created as per the instructions in MS CRM 2011 SDK JavaCrud example. But, we recently learned that it is for online MS CRM. Now we have no idea how to connect to CRM 2011 through Java.

Could you please help us with this?

Thanks.
