Generating the client proxy
Each web service in the BlackBerry® Administration API uses a WSDL file to describe the classes that the web service exposes. For the web services that you use, you should generate a single client proxy, to avoid duplicate copies of data types in the WSDL files. You should regenerate the client proxy when you upgrade or change the BlackBerry® Enterprise Server components.
Depending on the APIs that you want to use, you can generate the client proxy for the corews, utilws, and dispatcherws web services, and a client proxy for one of the email web services if you plan to use the messaging features. You should not generate the client proxy with multiple email web services. The corews web service is the only required web service.
