Recently I have been involved in scaling Hadoop for our Chip Multi-Threading (CMT) machines (e.g., systems running up to 256 threads per node.) Hadoop is a Java-based open-source MapReduce framework that enables users to deploy their cloud-friendly workloads across many computing nodes.

Open Choice isn’t some big, far-into-the-future vision thing it’s something we’re doing now. This year. Product-wise it consists of four offerings (where previously there was only one) and as we release them I’ll give you my perspective on why they’re important.

For a long time I've been looking for a web framework that would ease the development of web UI in portlets. Pure JSP is too old-fashioned and the abstraction it provides is just too low-level.

Today, I'd like to take a look at two different ways to create a poll component. Poll components are a way to periodically update a page with new information.

A few months ago, development on the new console for jBPM started. Initially, it was the intention that this console could also serve as the next console for jBPM 3 with the jBPM 3.3 branche initially being the target. Not much later, it was decided to only develop this console for jBPM 4 and the jBPM 3.3 branch was discontinued and 3.2 was the main stable branche again.

Many of us have had to ponder this question. Technology selection is notoriously difficult in the enterprise space since the criteria and complexity of the problem is often not fully understood until later in the development process.

This article describes how to use Portal Pack plugins to create and modify Sun GlassFish Web Space Server/Liferay themes on NetBeans IDE (Integrated Development Environment).

Using the annotation @EJB is not enough for glassfish to inject a new instance of a java bean in my class. Local EJBs are stored in the local naming service java:com/env and I haven't figured out why the Glassfish is refusing to use the same methodology as it use for remote beans.

About four weeks ago I went to a small event for developers where one of the speakers (christian dalager) compared Ruby on Rails to Asp.Net Mvc. One of the things that really caught my attention in Ruby on Rails was the ability to have an Action serve content in various formats like Json, Xml or Html just by changing the file extension of the requested resource.

Here are some quotes about running Rails applications on GlassFish from user@jruby mailing list...

One of my tasks for the Fusion Middleware 11g launch event was to build the JDeveloper/ADF part of the demo (along with Juan).

In this post I’ll show how to automatically open an issue in TFS when a test fails. This is a standard requirement, because in such a way you are immediately aware when some test are failing.
