To enable interoperability between Portlets and Portals, this specification will define a set of APIs for Updates to the Original Java Specification Request ( JSR). The Java platform provides an standard referred to as JSR that standarizes how portlets interact with portlet containers and ensures compatibility across. The Java Standardization Request (JSR ) defines a portlet specification, including a contract Enables interoperability among portlets and portals.

Here Portlets catalog are of use.

Developing JSR-168 Portlets

This security role must be defined in the Web deployment descriptor. Each Portlet produces a fragment of markup that it s combined with the markup of other Portlets, all within the Portal page markup. A way to set the credential and repository information per portlet instance instead of per portal would make the solution more flexible and usable.

Only one title per locale is allowed. Identification Request Contributions Section 1. An administrative name used to identify the portlet.

2. Java Portlet Specification (JSR)

To be determined by the expert group, initial target is December However, it does not address aggregation, security and personalization.

If this specification, or a future version of this specification, is included in a future version of a Java platform specification, this specification will remain available for use outside the platform specification, and will continue to be evolved outside porrtlets platform specification, unless both specification leads agree otherwise.


A portlet is managed by a portlet container.

Remote cache Additional settings must also be provided using a deployment descriptor extension ibm-portlet-portal-ext. Enterprise Content Management ECMsometimes referred to as “Enterprise Document Oortlets is a type of application that administers the storage, organization, classification, and retrieval of company data.

The transmission of the document contents to the client machine is handled through a servlet, ContentServlet Listing Five.

Portlet Info Specify the following portlet information for each supported locale. The portlet container will ignore all references to custom portlet modes that are not supported by the portal implementation, or that have no mapping to portlet modes supported by the portal. Typically, the portlet class is more complex as most portlets have multiple views view, edit, help, and so on and also have to handle user actions. Only one short title per locale is allowed.

Every client that loads the portlet is accessing the content source by impersonating the user that is represented by these credentials. Role link A string specifying the name of the application security role that the user may be mapped into.

What is JSR portlet specification and its advantages? | Web Portal Club

Many of them require the WAR to be run through a preparation tool or some other multistep deployment process. For details on deployment descriptors and other information, see “Introduction to JSR The username, password, and domain properties make up the credentials and are self explanatory.


Exact details will be agreed early in the life of the JSR and communicated to expert group members. A portlet container contains portlets and manages their life cycles. A Portlets Catalog is a set of portlets that are ready-to-use components for enterprise portals. Portlets are web components -like Servlets- specifically designed to be aggregated in the context of a composite page. From Wikipedia, the free encyclopedia. This design would not address the transport protocol for the remote execution of Portlets, leaving to the specific Portal implementations the support jxr Portlet remote execution.

A descriptive text about the portlet. Views Read Edit View history.

JSR 168 IBM extension for cooperative portlets

In this case, we extend the javax. Writing JSR portlets lets you become portal agnostic and lets vendors support a wider spectrum of platforms with little to no code changes. Because the code was developed to easily extend the ContentSource class, and therefore, provide implementations for jsd other than Documentum, this is the most obvious area for further development. A portlet responds to requests from a web client with and generates dynamic content.
