Class not Registered exception in java

I am consuming a SOAP webservice in JAVA. I have created stubs. When I Execute the code I am getting

    Server was unable to process request. ---> 
Retrieving the COM class factory for component with CLSID {28487481-0A2C-4E61-A198-417335F22895} 
failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

After googling a bit, I found out this is relevant to C#. But I am using JAVA. Not sure Why am I seeing this. Would be helpful, If you can throw some light on this.
