Article: Developing Portlets using JSF, Ajax, and Seam (Part 1 of 3)

Bookmarks

This article, the first in a three-part series by Wesley Hales, lays the framework for the rest of the series. It covers setting up a new project using JBoss Portlet Container and JBoss Portlet Bridge, configuring a JSF application to use JBoss Portlet Bridge, and the capabilities that JBoss Portlet Bridge provides to a JSF application.

From the article:

Portals have gained a lot of ground over the past few years, both in the enterprise and with the new enhancements of the portlet 2.0 (JSR 286) specification. The new 2.0 portlets allow you many freedoms in aggregating different applications and presenting them in different windows on one page. And of course, you get authentication, sophisticated personalization features, and better ways of handling AJAX out of the box.

With the JSR 301 portlet bridge specification, we now have a standard way of running JSF applications as both 1.0 and 2.0 portlets. The portlet bridge handles the portal Action/Render paradigm to properly handle the JSF lifecycle. While this tutorial is mainly to show you how easy it is to configure and develop a JSF portlet, I will also be revealing the new JBoss Portlet Container 2.0 and some of it’s cool new features.

    Looks like your download probably died early (reset) or it was corrupt for some reason. Just run 'mvn clean' and go through the process again.

    I am trying to work through the article but getting an error:

    C:\>mvn install cargo:start -Premote-portal -Dpc20
    [INFO] Scanning for projects...
    [INFO] Searching repository for plugin with prefix: 'cargo'.

    I setup Maven as instructed above. Am I missing something else?

    For some reason the automated downloading gets abrupted, and it's not due to bad network.
    Just download the files downloads.sourceforge.net/jboss/jboss-portletco... and
    downloads.sourceforge.net/jboss/jboss-portal-2.... manually and put in ./target/installs
    Run "mvn install cargo:start -Premote-portal -Dpc20" again and it will work.

    Make sure you are in the archetype directory that has been created.
