Oracle WebCenter supports Web Services for Remote Portlets (WSRP) versions 1.0 and 2.0. In the WebCenter Preconfigured Server page, you will find sample preconfigured portlets for both versions. In this example, you will use the
WSRP v2 WSDL link. WSRP 2.0 support is for a preliminary (that is, pre-production) version of WSRP 2.0. This standard provides support for inter-portlet communication and export or import of portlet customizations.
You can copy the URL from the address field of the browser. You will specify this URL while registering the WSRP portlet producer with your application.
