JSR286 explained: Portlet Filters

Portlet FilterIn the "JSR 286 explained" series, see the commentary on  Portlet Filter, one of the new features in portlet 2.0 (PLT.20)

Filters are Java components that allow on the fly transformations of information in both the request to and the response from a portlet.

The other features previously covered in "JSR 286 explained" series are Resource Serving, Eventing, Caching and Public Render Parameters.

JSR286 explained : Public Render Parameters

Recently the JSR 286 draft was released for public review. The list of major changes in this new spec can be found in a previous blog.

In JSR 168, the render parameters set in processAction is only available in the render of the same portlet.

With the new feature "Public Render Parameter", the render parameters set in the processAction of one portlet will be available in render of other portlets also. Using public render parameters instead of events avoids the additional process event call.

See some commentary on the Public Render Parameter feature.

JSR286 explained : Caching

CachingThe public review draft of JSR 286 was released recently and the details of that can be found in Deepak's blog. Markup caching has been a part of JSR 168, but it had its limitations. JSR 286 addresses these limitations by introducing "Validation" caching and "Public" caching scope among other things. The details and the comparison of the JSR 168 and JSR 286 caching mechanism are available in my blog entry.

These improvements will be part of the OpenPortal Portlet Container soon and the performance gain thus obtained would truly be tangible :)

Consumables from the OpenPortal Community

OpenPortal Community Some time back we had decided to open source some on the key components of the Sun Java Portal Server product in a piece-meal fashion. The idea was to enable those components to be consumed by other communities or software products (refer this article for the goals).

Since then we have open sourced the Portlet Container (based on the JSR168 standard) implementation, the WSRP implementation, the JSFPortlet bridge, and also created some new innovative projects such as Portal Pack (NetBeans and Eclipse), SAW and Mirage. And to further walk the talk, I am happy let you know that some of these components have already been consumed back by the enterprise class open source Portal Server implementation in the OpenPortal community.

A successful open source community is about adopting other communities and getting adopted by other communities, I would like to welcome other communities and software products who believe in open source to come and look at what we have to offer as part of the components mentioned above.

To go back to the article that states the goals of the OpenPortal community --

The objectives for the Portal Server open-source initiative are threefold:

- Expose Portal Server's mature and proven enterprise-class capabilities to the community and evolve it there through active participation from the community of developers, users, partners, and like-minded individuals.

- Build composable, decoupled, and lightweight components that can be used by the developer community and other projects, for example, components that serve as development or test runtimes in tools.

- Collaborate with other portal, middleware, or similar open-source efforts in the software universe for the benefit of the community.

Note: Please stay tuned for news on JSR286 and WSRP 2.0.

Using Portal Pack For Sun Java System Portal Server

The Portal Pack provides a server plug-in for Sun Java System Portal Server 7.1 (including Update 1). Using this plug-in you can develop and deploy your portlet application on a remote Sun Java System Portal Server directly from your NetBeans IDE. If you are wondering how to start using this plug-in for your Portal Server installation, you may want to go through the following documents --

New SDN Article: Configuring Portlets for Internationalization and Localization

i18n image 

Mahipalsinh and Marina have just published a new SDN article titled -- "Configuring Portlets for Internationalization and Localization"

The article uses a sample portlet to describe the procedures for internationalization, localization, and deployment of internationalized portlets on Portal Server. That is, you learn how to display portlet content in various languages and how to add new language support to existing portlets.

Note: for all Portal Server related articles, you can use the "article" tag on The Portal Post.

Flex Up Your Portlets!

Flex PortletsIf you want to build a rich user interface web application that requires several state changes, spans multiple business processes and requires complex data handling at the back-end and still want to give the users a really rich and consistent experience (no refreshes!), then do have a look at Flex as I believe that it is definitely a good choice.

Refer Sandeep's blog to get a fair idea regarding flex and it's advantages. After that if you are ready to try your hands on it, have a look at my blog where I have explained this with an example.

Deploying Portlets on OpenPortal Portlet Container

Screencast After receiving quite a few queries from users, I thought it was prudent to post the various ways of deploying JSR-168 portlets on the OpenPortal Portlet Container. The use of GUI provided by the driver, the CLI provided by the ant task and the auto-deployment feature for drag and drop deployment, are all very easy to use and provide flexibility to the developers. These are elaborated in detail in this blog post.

 So start creating those portlets and get them up and running in a matter of seconds.

Voice-over Screencast to Demonstrate IPC StoryBoard Feature for NetBeans 5.5/5.5.1 IDE

ScreencastHere is a new voice-over screencast that demonstrates the IPC StoryBoard feature for NetBeans 5.5/5.5.1 IDE. In this screencast, I have explained the IPC StoryBoard feature with the help of a fund transfer portlet application created in NetBeans 5.5.1 IDE, following the procedure in Uma's tutorial.

Thanks to Satya, Vihang, and Deepak for providing feedback. I would also like to thank Anjana Rudra for graciously lending her voice and Manu Samuel from the IEC Media design team for the production support.

Watch the screencast and look out for more in the future.

Portal Server 7.1 Update 1 Release Available For Download

OpenPortal Portal Server 7.1 Update 1 is a maintenance release addressing major bug fixes from the previous releases along with some significant new features and enhancements. In particular, this release addresses some of the gaps specifically around community functionality. The new feature set includes the ability to create private  communities, allowing cross community search and management of communities via admin console. Other notable features include the AJAX portal container and the ability to create blogs.

For Solaris and Linux platforms, the release is available both in the form of an upgrade (via patches) and as a fresh install.

For Windows platform, we have taken a simple approach and are making this release available only in the form of a  pre-configured install, without an upgrade option. The main reason for taking this approach is that the earlier release of Portal Server 7.1 on Windows (part of Java Enterprise System 5 bundle) was somewhat difficult to install and required quite a few workarounds to configure the product.

This release simplifies the install experience and speeds up the evaluation and development  process. It is highly recommended that the Windows release should mainly be used for development and  evaluation purposes. 

The Portal Server 7.1 Update 1 release is available for download at this location.

Also note that the Java Application Platform SDK streamlines enterprise application development and improves developer productivity. A new version, Update 3 Preview 2,  is now available for download. In this release the Portlet Container has been updated from the earlier 1.0 beta version to 1.0 FCS.
