You can use the built-in service pub.remote:invoke to invoke a service on a remote Integration Server and return the results. The remote server is identified by an alias, which is configured on the Remote Servers screen in the Integration Server Administrator. The pub.remote:invoke service automatically handles opening a session and authentication on the remote server.

The pub.remote:invoke service resides in the WmPublic package and requires the alias of the remote server and the fully qualified name of the service that you want to invoke as input. For a complete description of this service, see the webMethods Integration Server Built-In Services Reference.
