The Program Call wizard generates three classes. One of the classes is a Java bean which can be used by the Web Services wizard to create a Web service. Its name is YourBeanNameServices.java. The other two classes are named YourBeanNameInput.java and YourBeanNameResult.java. These classes are required by the Java bean class for input and output parameters.
For every program that you define in the Program Call wizard, two methods are generated. You can use either one of the methods to get the data returned from the remote program call.
