You can add a registry, business entity, business service, service interface, WSIL, or WSDL service to the Web Service Explorer Favorites if you plan to access them in the future.
To add a registry, business entity, Web service, service interface, WSIL, or WSDL to Favorites using the Web Services Explorer:
Any favorites that you add are saved by the Web Services Explorer to
X:\workspace\.metadata\.plugins\com.ibm.etools.webservice.explorer\favorites.wsil
Where X is the directory where your workspace folder is located. If you are migrating from an earlier version of the product, your favorites will be automatically migrated to this location.
