Integration with solution manager 4.0 - service desk with XI ?

Hello Experts,

Does any one know how to integrate the solution manager 4.0 - service desk with SAP XI. I read the solution manager 4.0 service desk web service api, but it only has the XSDs. If any one can provide me any step by step procedure for creating the webservice through this api and publishing it....WILL DEFINETLY BE REWARDED.

Thanks,

Raju.
