Using WSDL References for Efficient Design

A BPEL process uses the definitions from Web Services Description Language (WSDL) files. WSDL files contain the namespace, partner link types, operations, and messages needed to define process activities, and WSDL files are required in order to create a valid, executable BPEL definition.

You can generate WSDLs in Designer or you can add WSDL files to the Project Explorer view of ActiveVOS before you begin to create a process definition.

WSDLs provide several key productivity features:

• You can drop a WSDL operation onto the Process Editor to automatically create an appropriate Web Service interaction activity (Receive, Receive/Reply, Invoke, OnMessage, or OnEvent)
• You can automatically create the appropriate WSDL extensions required for a BPEL process, if they do not already exist (partner link types, properties, property aliases)
• You can use the WSDL definitions across processes

See the following topics:

• Interfaces, Service References, and Local WSDL
• Creating WSDL Extensions for BPEL
• Starting a Process by Dropping an Operation onto the Process Editor
