Using the Web Services Eclipse plug-in, you can invoke a service’s operations:
In Eclipse, expand the collection (ws is the default), then expand the Operations folder under the service name.
Right-click the operation, and choose Invoke from the menu.
Specify the input values, if required for the operation, then click Invoke. The results display.
To create a test client, use either of these tools; both are described in the Web Services Toolkit User’s Guide:
Management Console—see Chapter 5, “Management Console—Web Services,” or
wstool utility—see Chapter 9, “Using wstool and wstant.”
