WSRP Reincarnation of Service Oriented Architecture Asif Akram1, Rob Allan1 and Rob Crouchley2 1 e-Science Centre, CCLRC Daresbury Laboratory, Warrington WA4 4AD, UK 2 e-Science Centre of Excellence, University of Lancaster, UK Abstract Portlets are not confined to one portal framework; Web Services for Remote Portlets WSRP defines standard for interactive, user-facing Web services to make portlets hosted by geographically distributed portal frameworks accessible in single portal.
This remote sharing of portlets will greatly ease the construction of large-scale portal based systems, or Virtual Research Environment, enabling them to be more scaleable, manageable and maintainable; core theme of Service Oriented Architecture SOA, service oriented architecture research papers. WSRP is suggested to be natural tool for SOA systems; provides the missing presentation layer with additional needed features in the existing SOA.

The complementary Web Services for Remote Portlets WSRP specification was created by the Organization for the Advancement of Structured Information Standards OASIS with input from a number of commercial organisations [2,3]. It is based on mature XML and Web services specifications that allow the plug-and-play of services in portals and other Web applications that aggregate content from disparate sources, service oriented architecture research papers.
WSRP is a cross-vendor protocol that defines a set of interfaces for enabling portal and non- portal Web applications alike to incorporate portlets deployed remotely. It was designed to enable businesses to provide pre-defined interfaces to content or applications in a form that does not require any manual service oriented architecture research papers by consuming applications, service oriented architecture research papers. WSRP thus Figure 2 Components of WSRP architecture enables developers to consume portlets published by other portal sites, regardless of the business system The WSRP Specification defines the following actors Portal Framework they use.
It allows business level within WSRP architecture: tools to integrate different similar and related portlet services in a dynamic service oriented architecture research papers coupling of services on ƒ WSRP Producer: Producers are modelled as the fly by publication and discovery in registries such as containers of portlets.
The Producers are Web UDDI using WSDL. Like any Web service, service oriented architecture research papers, WSRP is service with common set of operations such as: also language agnostic although tooling currently only Self Description, Mark up, Registration, and exists in Java. Portlet Management. Producers can optionally manage the registration of consumers and require Components of WSRP them to pre-register prior to interacting with portlets.
A registration establishes a relationship It is important to explore different components in WSRP between Consumers and Producers. Every producer in interaction with another portlet on the same page WSRP is described using a standardized WSDL takes place. A WSRP service through the Service Description and Mark- portlet is not a Web service in its own right it up interfaces.
Through this mechanism a producer cannot be accessed directly, but instead must be can customize its behaviour to a specific type of accessed through its parent producer. For example, a producer might filter the set of offered portlets based on a particular ƒ WSRP Consumer: This is a Web service client consumer.
In addition, the Registration Interface that invokes producer-offered WSRP Web services serves as a mechanism to allow the producer and and provides an environment for users to interact consumer to service oriented architecture research papers a dialogue so that they can with portlets offered by one or more WSRP exchange information about each others' technical producers.

A consumer would have the ability Interfaces for WSRP to customize a portlet's behaviour or even destroy To standardize communication between WSRP an instance of a remotely-running portlet using this consumer and WSRP producer, WSRP defines a set of interface.

Standardizing Communication Sequence these interfaces allows a portal to interact with remotely- Most powerful capabilities in WSRP is the ability to running portlets generically, since it has a well-defined dynamically leverage applications from others servers.

The WSRP Specification requires and associate different portlets that are available from that every producer implement two required interfaces, different WSRP Producer Portals in the network while allowing them to optionally implement two others provided WSRP Producer publishes themselves in the as well [8]: global Universal Description, Discovery, and Integration UDDI [9].

Typical consumers. A WSRP consumer can use this discovery scenario consists of following message interface to query a producer to discover what sequences among WSRP Consumer, WSRP Producer portlets the producer offers, as well as additional and End User. metadata about the producer itself. This interface can act as a discovery mechanism to determine the set of offered portlets, but also importantly allows consumers to determine additional information about the producer's technical capabilities.
The producer's metadata might include information about whether the producer requires registration or cookie initialization before a consumer can interact with any of the portlets. For example, a consumer would use this interface to perform some interaction when an end-user submits a form from the portal page.

Service Oriented Architecture Modular software is required to avoid failure in large systems, especially where there are complex user requirements. The concept of a Service Oriented Architecture SOA was developed to avoid the problems of having to re-write large portions of code to accommodate changing requirements. A SOA is essentially a collection of autonomous, self contained, pluggable, loosely coupled services which have well- defined interfaces and functionality with little side effect.
A service is thus a function that is self-contained and immune to the context or state of other services. in a the network. Enterprise software is not usually that workflow. SOA is an architectural style whose goal is to flexible and it was not built to be used as services so achieve loose coupling among interacting software companies have to add service layers to expose service oriented architecture research papers agents; stateless processors.

In WSRP the consumer, in this case via a portlet.
