Open-Sourcing Java

Larry Gets His Way with Java

Tue, 07 Dec 2010 23:29:00 EST

The open source Apache Software Foundation failed to rally the Java Community Process (JCP) to its side and force Oracle to release the Java compatibility test kits (TCKs) that would let it certify Project Harmony, its breakaway open source version of Java Standard Edition for Linux, as real Java, and rescind the Field-of-Use (FOU) restrictions that make it impossible for Harmony to be distributed under an Apache License whether it’s certified or not.

Seven Observations On Software Maintenance and FOSS

Fri, 04 Dec 2009 06:00:00 EST

The November 2009 issue of Communications of the ACM (CACM) has a very interesting article by Paul Stachour and David Collier-Brown entitled “You Don’t Know Jack About Software Maintenance”. The authors argue energetically for using versioned data structures and “continuous upgrading” to improve the state of the art of software maintenance. The piece got me thinking about FOSS (Free and Open Source Software) and “continuous upgrading”. Here are seven observations on FOSS software maintenance that occurred to me as I reflected on the CACM article:

Bridging to Open Ajax

Tue, 08 Sep 2009 12:45:00 EDT

The Open Ajax Alliance is a standards organization with the mission of ensuring interoperability within Web based Ajaxified applications. One of their standards relates to intercomponent communication - the ability to subscribe and publish messages which can then be picked up by code written by other authors. Please note that if you don't have an interest in Open Ajax, this post may not be especially illuminating - I've talked about the addOnEvent function before, even recently.

SOASTA Announces Cloud-Based Performance Certification Program

Tue, 21 Jul 2009 07:45:00 EDT

SOASTA, the leader in cloud testing, today announced a Performance Certification Program designed to enable companies deploying software in the Cloud, at hosted data centers, or behind corporate firewalls to certify that their website has been tested and has met or exceeded industry benchmarks for performance at peak levels of user traffic. Whether due to cost, complexity or lack of resources, the vast majority of web applications and sites have not been tested at normal user volumes, much less for unexpected spikes in traffic. The user community has become the testers for most Web 2.0 sites, a risk that has proven very costly time and again.

Twelve Things You Didn't Know About Jetty

Fri, 10 Oct 2008 19:15:00 EDT

In the past couple of years, interest in Jetty has surged. Jetty is an open source Java-based web and application server and servlet container, but what else do you know about it? To commemorate the 12th anniversary of Jetty, here are 12 things that might surprise you

Is Open Source Good for the Java Developer?

Mon, 23 Jun 2008 12:15:00 EDT

Commercial open source software has arrived. There have been commercial sponsors of open source projects for a long time, but the recent spate of high-price (for open source, at least) acquisitions of companies with open source products at the core of their business has made a splash in the technology industry. In addition, Sun's convulsions into the open source world have left the Java landscape decisively in open source territory.

Determining the Value of Open Source Software

Sat, 03 Nov 2007 17:45:00 EDT

Open source technology is a boon to companies that want to add features and functionality to their applications without the overhead. It eliminates the cost of databases, operating systems, and other infrastructure components, enabling quick and cost-effective access to new features. According to a survey conducted by IT research firm Optaros, companies with more than $1 billion in annual revenue reported average savings of $3.3 million in 2004 as a result of open source technology (September 2005). A similar survey conducted by IDC showed that open source databases are used by 33% of the 600 companies it surveyed.

Focusing on JEE Java Development: Mylyn and Spring

Sat, 06 Oct 2007 08:45:00 EDT

As developers, we're familiar with the endless pains that result from maintaining overly complex systems. Some complexity is accidental, so we continually strive to remove its overhead from our application. The latest crop of frameworks and dynamic languages has demonstrated just how far simple implementations can go. However, many applications have an essential complexity that cannot be further reduced without sacrificing end-user functionality or integration.

How Open Is "Open"? – Industry Luminaries Join the Debate

Thu, 01 Mar 2007 05:00:00 EST

In order to describe itself as an 'open source' company, need a company merely be 'a company that will help you make the switch to open source in your company' - or does it have to be one that lets users feely download, compile, and use the software in question? Where is the dividing line? How open is 'open'? At Enterprise Open Source Magazine we contacted a range of FOSS luminaries for their take on the issue.

Fault Tolerance with Open Source and JVM Clustering

Wed, 01 Nov 2006 14:00:00 EST

Many in the Open Source community (including the camps following Tomcat, Geronimo, Struts, Spring, and Hibernate) have chosen to focus on solving problems of developer efficiency and software elegance, and are sometimes forced to leave production operating characteristics such as HA (high availability)/fault tolerance and central management control for future releases. Or, in some cases, the elegance of the framework stems from its lightweight nature and thus the user community as a whole can't be made to suffer the complexities of clustering and HA for the needs of the few.

Open Source Software, Standards, and Java

Mon, 25 Sep 2006 16:00:00 EDT

Sun Microsystems recently announced its intentions of finally publishing Java under an Open Source license. But what does that actually mean? We'll take a quick look at what it means to be 'Open Source,' how the Java language specification compares to other more formal language standards, and the importance of the brand and certification programs. We'll then look at what benefits Sun may get from distributing Java as Open Source and at some of the problems that will have to be addressed.

Hello Dali!

Sat, 23 Sep 2006 16:00:00 EDT

On June 26, 2006 the Eclipse Foundation announced the availability of new releases of 10 Open Source projects. This simultaneous release event, named Callisto, garnered a lot of attention for the 10 projects involved. But, meanwhile, on the same day and without much fanfare, not even a press release, the Dali JPA Tools project shipped its first formal release numbered 0.5. With the release of Dali 0.5, developers now have a solid set of tools for developing applications for the new Java Persistence API (JPA) in Eclipse.

Barbarians at the Gate

Fri, 22 Sep 2006 20:30:00 EDT

Open Source means different things to different people. For some it's a business model. For others it's a way of collaborating. Some see it as a way of reducing costs. And some are out to change the world.

Eclipse: A Solid Desktop, Rich-Client, or Embedded Application Framework

Mon, 31 Jul 2006 18:30:00 EDT

By now, you've probably heard about Eclipse as 'the Open Source Java IDE' (). Today, several companies have looked past the Java IDE plug-ins provided as part of Eclipse, and are creating products that use Eclipse as a tool integration platform, both inside and outside of the Java arena. But what about using royalty-free, Open Source Eclipse technology as a general-purpose application framework for your next desktop, fat client, or embedded application? With the support provided by the Eclipse Rich Client Platform (RCP) and the embedded version of the same (eRCP) the idea is certainly not as strange as it first sounds. So we'll explains why Eclipse is a solid desktop, rich-client, or embedded application framework with the potential to greatly simplify and accelerate development as well as forever change the way developers think about writing Java applications.

A Look at the Eclipse Callisto Release

Mon, 24 Jul 2006 18:00:00 EDT

Callisto is the simultaneous release of 10 major Eclipse projects at the same time. An important thing to note about Callisto is that even though it's the simultaneous release of 10 projects, it doesn't mean these projects are unified. Each one remains a separate Open Source project operating with its own project leadership, its own committers, and its own development plan. In the end, Callisto is about improving the productivity of developers working on top of Eclipse projects by providing a more transparent and predictable development cycle.

The Benefits Of The AJAX RenderKit

Wed, 14 Jun 2006 13:30:00 EDT

In an effort to provide developers with a productive environment, Oracle has been working on a very rich UI component framework for several years. This framework - ADF Faces - has now been donated to the open source community. More precisely, it has been donated to the Apache Software Foundation and is currently hosted in the Apache Incubator - http://incubator.apache.org/projects/adffaces.html.

Flashback to '04: IBM to Sun – "Let's Collaborate on Open-Sourcing Java"

Thu, 04 May 2006 10:45:00 EDT

Two years ago Rod Smith, IBM Software's VP of Emerging Technologies (and still with IBM today), wrote an open letter to Rob Gingell, Sun's Chief Engineer (now with Cassatt). IBM, Smith said, 'would like to work with Sun on an independent project to open source Java.'

Open-Sourcing Java: The Great Debate Begins Again

Thu, 04 May 2006 09:30:00 EDT

'The fact that there is so much discussion going on is of interest,' wrote Sun's John Clingan in his blog yesterday. The discussion is 'all over the map,' Clingan noted: 'Some like the idea of Open Source Java. Some think that will negatively affect WORA. There doesn't seem to be any general consensus building. Perhaps that means there is a tremendous amount of pent-up innovation.'

Flashback to '04: "Let Java Go" – ESR Writes Open Letter to Sun

Thu, 04 May 2006 02:30:00 EDT

Responding to remarks at Sun's February 2004 analyst meeting, Eric S. Raymond - President of the Open Source Initiative - in February 2004 wrote an Open Letter to Scott McNealy. The letter ends: 'Mr. CEO, tear down that wall. You have millions of potential allies out here in the open-source community who would love to become Java developers and users if it didn't mean ceding control of their future to Sun. If you're serious about being a friend of open source, if you're serious about preparing Sun for the future we can all see coming in which code secrecy and proprietary lock-in will no longer be viable strategies, prove it. Let Java go.'

Flashback to '04: Gosling Says "Open-Sourcing Java Could Promote Interoperability"

Thu, 04 May 2006 02:15:00 EDT

'Carefully done, open-sourcing [Java] could actually promote interoperability by making it easier for disparate groups to align behind one code base,' wrote Sun's James Gosling in his widely read java.net blog at the end of April 2004.

Yared to Sun: "Why Is It Good to Open Source OpenSolaris...and Bad to Open Source Java?"

Wed, 03 May 2006 03:15:00 EDT

'Why is it good to open source OpenSolaris and OpenOffice and bad to open source Java?' In an Open Letter to Sun's Jonathan Schwartz, that's what ActiveGrid CEO Peter Yared asked, back in March. Yared added: 'Can you please answer the following question with a single coherent sentence that people can remember and repeat? If I ask five Sun employees this question, I get five different answers, so having simple answers to these questions will clearly help your own workforce as well as your customers and prospects!'

Sun's Open Source Push Gathers Speed

Tue, 02 May 2006 10:15:00 EDT

'For Sun,' said Simon Phipps in a recent interview, 'the open source message is a very natural 21st century expression of how Sun has been doing business for more than 20 years.' Given that Phipps is Chief Open Source Officer at Sun, it is hardly surprising that he should be keen on what he sometimes calls, engagingly, the Zen of Free. With Phipps as OSO, Sun under Jonathan Schwartz is assured of a vibrant and high-profile role in the open source community.
