Voice-over Screencast to Demonstrate the Simple API for Workflow (SAW) Plug-in

The SAW feature in OpenPortal is intended to offer a generic workflow API, to perform human workflow interaction with various workflow engines. This generic workflow API will ship with a default implementation for Java Composite Application Platform Suite. Currently, the Workflow API, Workflow Tag Library, Sample portlets, and Tooling Plugins for developer IDE's are provided in the SAW home page.

In this screencast, you will learn how to:

  1. Perform human workflow interaction with Java Composite Application Platform Suite workflow engine
  2. Add SAW plug-in in NetBeans IDE,
  3. Create a simple web application using the drag and drop features in SAW plug-in 
  4. Create a simple a simple SAW portlet, which lists tasks based on task ID

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.

Code for freedom!

Code For Freedom To commemorate India’s 60 years of Independence, we have announced a unique contest today, aptly named “Code for Freedom”.

Open to undergraduate and graduate students in any college/university accredited by the Government of India, the contest invites contributions to 5 Open Source projects namely OpenSolaris, NetBeans, Project GlassFish, Apache Derby and OpenPortal and will run until January 2008. The winners of the contest are set to win Laptops, iPods and every contributor gets a T-shirt and certificate from Sun.

You can find more information at the Code For Freedom site.

As you have come to this blog, I am assuming you are interested more in an open source enterprise portal - and we will be very happy to help you in any way we can. You can contact us at users@portal.dev.java.net.

If you want to contribute to the development of the OpenPortal project, you can find details over here

If you want to create cool JSR168 based portlets, please check Satya's blog to learn about some easy steps on how to do portlet development.

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.

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.

OpenPortal at University Day in Bangalore!

I had been to University day at Acharya institutes in Bangalore to showcase OpenPortal
technologies. I have covered Portlets basics, OpenPortal Portlet Container ,
Netbeans Portal Pack.

 I had a wonderful time and got good response from students. For details of trip read here.

Tips: JSF Portlet Bridge in Maven Repository

We now have the JSF Portlet Bridge jars available on the java.net maven2 repository.

If you use Maven2 to build JSF Portlet webapplications, you can reference the JSF Portlet Bridge library in your pom.xml as shown below. After the war is built, it will contain jsf-portlet.jar

So insert the following into your pom.xml --

Under <repositories>
            <name>Java.net Repository for Maven</name>

Under <dependencies>

The current versions are 1.2.1 and 1.1.5

Whenever the new version materializes in the JSF Portlet Bridge Project, it will also be made available via maven2 repository
