JSR 168 portlets
Use these settings to define properties received through WebSphere® Portal from other JSR 168 portlets (HATS or non-HATS) on the portal server. Click Add to add a new property. In the Property field enter the name of the property that is being received. The name must match the property name used by the sending portlet, for example, the same property name used by the Send global variable action in a HATS JSR 168 sending portlet. In the Global variable field enter the name of the global variable to use to store the value of the received property. If the global variable is indexed, enter the index to use. Select the Shared check box if the global variable is a shared global variable.
When you click Finish, the property is added to the project's application.hap file. In addition, a Web Services Description Language (WSDL) file is created, if one does not already exist, and a receive property is defined in the WSDL file. The name of the WSDL file is <project_name>.wsdl. The WSDL file is required to wire the portlets using the WebSphere® Portal wiring tool. The portlet.xml file is updated to reference the location of WSDL file.
