Integration Broker Web Service Discovery Class


Use the Web Service Discovery class to:

  • Find web services currently offered by the Integration Broker.
  • Retrieve the web services description language (WSDL) for a given web service.

The methods in this class are intended to be used in pairs. First, use one of the "Find" methods to get the list of web services, then use one of the "Get" methods to retrieve the WSDL for the given service.

The PeopleSoft Integration Broker Web Service Discovery objects are declared as type

WebServiceDiscovery. For example,

Local WebServiceDiscovery &theDiscovery;

&theDiscovery = create WebServiceDiscovery();

A Web Service Discovery object can be instantiated from PeopleCode, from a Visual Basic program, from Java, COM and C/C++. This object can be used anywhere you have PeopleCode, that is, in an application class, Application Engine PeopleCode, record field PeopleCode, and so on.

The Integration Broker Web Service Discovery class is not a built-in class, like rowset, field, record, and so on. It is an application class. Before you can use this class in your PeopleCode program, you must import it to your program.

An import statement names either all the classes in a package or one particular application class. For importing the Integration Broker Web Service Discovery class, PeopleSoft recommends that you import all the classes in the application package, although you won't be using most of the classes in these application packages.

The import statements you should use are as follows:

import WEBSERVICES:*;

import SOAPTOCI:*;

Local WebServiceDiscovery &theDiscovery;

&theDiscovery = create WebServiceDiscovery();

    WSDL is the future for not only for peoplesoft applications but for all the applications which serves seamless integration with the third party systems.
