Using WSRP 2.0 with JSR 168 and 286 Portlets

WSRP—Web Services for Remote Portlets—specification builds on current standard technologies, such as WSDL (Web Services Definition Language), UDDI (Universal Description, Discovery and Integration), and SOAP (Simple Object Access Protocol). It aims to solve the problem of traditional data oriented web services which required the applications to be aggregated prior to any specific presentation logic could be applied for presenting the content. Portlet standard (Java Community Process, 2005) complements WSRP mechanism by defining a common platform and APIs for developing UI in the form of portlets. WSRP enables reuse of an entire user interface. One of the advantages is that only one generic proxy is required to establish the connection.At present, portlets based on JSR 168 (Java Community Process, 2005) as well as JSR 286 (Java Community Process, 2008) specification are often used in portal applications. This paper examines the relationship of WSRP specification with the portlet specification JSR 168 and evaluate some and shortcomings of WSRP specification 1.0 (OASIS, 2003). We discuss the impact of WSRP 2.0 (OASIS, 2009) and portlet specification JSR 286 (Java Community Process, 2008) on “on glass” integration paradigm.
