Partner Link elements identify the parties that interact with our business process.
Each link is defined by a partner link type and a role name. The Partner Link Type
determines the relationship between a process and its partners by defining the roles
played by each service in a conversation. The relationship is further determined by
specifying the port type provided by each service to receive messages. Each role
specifies one port type in the WSDL file. You use a single role for a synchronous
operation, as the results are returned using the same operation.
When you drag-and-drop a web service into the diagram, the BPEL
Designer retrieves the WSDL file from the Application Server. To
successfully retrieve the WSDL file, the Application Server should be
running and the web service project must be deployed.

In the Partner Link editor window, you can choose whether to use the existing
partner link type or create a new partner link type. If the WSDL file you selected
contains partner link types, the Use Existing Partner Link Type option is selected
automatically and the Partner Link Type drop-down list is populated with the
partner link types found in the WSDL file. You can use one of the existing partner
link types or select the Use a Newly Created Partner Link Type option to create a
new partner link type.
