By now we are all familiar with the debate over open source software versus proprietary software. We understand both models for the most part. Open source means the source code of the program is free to modify but in the end money is still made on software via support for it or using community input to sell a better product. Proprietary software is the Microsoft Office or Mac OS operating system software we buy. The consumer has no direct input into the software but can obtain a certain level of free support for it.

However the debate continues as each camp tries to out-sell the other. From a Systems Integration point of view do you recommend JBoss or Websphere for a client solution?

In order to provide searching within the portal a strategy had to be defined with how to integrate Alfresco with GSA. There were two approaches considered:

1. Utilize the traditional approach and have GSA crawl Alfresco through either a webscript mechanism or via CIFS.

2. Utilize the GSA Feed based approach.

After careful review we decided upon the feed base approach for the following reasons:

1. Meta Data: In order to support the Faceted searching, we need to find a way to attach metadata to each content item. Given that our HTML code is just snippets and does not contain a header with this information and that we are indexing documents, the only way to reliably accomplish this was via the feed.

On my current project, we are using Alfresco and working on an integration with JBoss Portal. In this case we were building a component that allowed for the browsing, uploading, moving, renaming, and deleting of files. We had built all the Alfresco Web Scripts to support these operations. In order to ensure the proper auditing of the changes, we needed to implement a WebScripts component that performed impersonation of the user that was executing the action. After some Google searching, we found the following common solution to the problem:

public String impersonate(String username) {
String currentUser = AuthenticationUtil.getCurrentUserName();

On my current project we were recently faced with an interesting security issue.  The heart of the problem was that we had a set of secured EJB 3 services that needed to be called from a jBPM engine in the same container that for various reasons was not in a security domain.  Here I'll go over the way we chose to solve the issue and show some snippets of the "proof of concept" unit test.

The solution we eventually came to involved using an EJB 3 interceptor to inject a custom system principal around any BPM "actions" that needed to call secure services.  This approach allows the interceptor to be reused for any unsecured system components and is configuration driven, as we'll see later.

On my current project, we are using Alfresco and working on an integration with JBoss Portal. In particular, we were creating our own version of Alfresco WebForms editor that is built into their web client.

I’ve always been an open source fan and for the past 2 or 3 years I’ve been working with JBoss products - lately JBoss Portal. So, I decided I want to become more active in the JBoss Portal forums on JBoss.com - unfortunately, though, their forums aren’t RSS-enabled and I’m a big RSS user.

So, I decided to use one of my favorite, free web-tools - Yahoo Pipes - to build an RSS feed for the JBoss.com forums.

Before the Portlet 2 specification (JSR286), the recommended method for adding AJAX functionality to a JSR168 portlet was to deploy an additional servlet to the portal server (either inside the same WAR as your portlet(s) or in a stand-alone WAR) to handle asynchronous requests.

The goal of this article is to show you how to use pack:tag to optimize the performance of your JBoss Portal theme. I’ve used this approach on a production JBoss Portal 2.6 implementation and tested the approach out in version 2.7.
