Using the enterprise service discovery wizard to find services follows a similar pattern regardless of the system you are searching for services.
Prior to using the enterprise service discovery wizard, you perform some configuration tasks. For example, you would need to import a RAR file into your workspace if you intend to use it to access an EIS system through a resource adapter. You would need to specify the location of a WebSphere Service Registry and Repository if you intend to access that registry.
Then you would follow this pattern with the enterprise service discovery wizard to get the objects from the system you are searching.
