(InfoWorld) - Sun continues to work on the Java Kernel, the idea of which is to provide a subset of the Java Runtime Environment tuned to particular programs. Formerly known as Java Browser Edition, the Java Kernel is planned for release as part of Java Standard Edition (SE) 6 update 4, probably in early-2008, a Sun representative said on Friday. Developers will have early access to the code to provide feedback. An original intent was to make Java like a Flash plug-in and enable a resurgence of Java on the browser. Applications would specify which features they need, such as Swing and XML parsing, said Sun staff engineer Ethan Nicholas, who is working on the project. "The basic idea was that the current Java Runtime Environment is simply too big, and most programs require only a small subset of the functionality," Nicholas wrote in September 2006 on his blog. "The 'browser edition' that I suggested would enable you to install exactly the subset of Java that your particular program required, but you would be able to download all of the other functionality on demand (and thus be fully compatible with J2SE)." Some Sun employees doubted the project would fly, according to Nicholas. Even a detailed analysis of the idea painted a bleak picture, he said. "The feature did in fact get submitted as a proposal for Java 7 under the name "Java Kernel" (the idea being that you download a small "kernel" of Java functionality, which is in turn capable of downloading the rest of it)," Nicholas said. Nicholas said he developed a stripped-down JRE installed containing only enough functionality to run "System.out.println," or "Hello World." To determine which files were necessary for the project, Nicholas wrote a program to iterate through the JRE files. "After going through all of the files in this fashion, I was left with an extremely minimal JRE that could run Hello World and ... well, that's about it. But it at least provided a starting point. Building a working installer from this JRE was itself a challenge because several of the files that weren't necessary to run Hello World were still necessary to successfully install the JRE, but I persevered and now have a fully functioning, minimal JRE," Nicholas said. Comments about the project posted on Nicholas's blog varied. "I also believe modularization of the JRE is the solution. Not just for the size of the download, but also for different other issues," one commenter said in 2006. "The problem here is that Java isn't just a browser based technology, it's a platform. When I write a Java applet or application, I expect the platform to be there," said another respondent.

SableVM is a robust, extremely portable, efficient, and specifications-compliant Java Virtual Machine that aims to be easy to maintain and to extend. It features a state-of-the-art and efficient interpreter engine. Its source code is very accessible and easy to understand. It also has many robustness features that have been the object of careful design.     SableVM is a clean-room implementation of the publicly available specifications.    In this version, we added an experimental generational garbage collector, we imported a new GNU Classpath snapshot, we added handling of Jar/Zip files on boot classpath, we added user-friendly failure messages for bootstrap problems, we added added a profiling switch, we made sablevm-classpath install its files in standard locations, we made jikes and gcc be less verbose by default, and we made several important bugfixes and improvements.  You can download the SableVM from: http://sourceforge.net/project/showfiles.php?group_id=5523&release_id=281502

Looking to make Web development easier for Java developers, the Apache Software Foundation began offering this week Apache Wicket 1.3, an open source component-based Web framework.Formerly housed at SourceForge, the Wicket project moved over to Apache last year; version 1.3 is the first release bearing the Apache nameplate, said Martijn Dashorst, chairman of the project and a senior software developer at Web application development firm Topicus. Enhancements have been made in areas such as AJAX (Asynchronous JavaScript and XML) and portal support."The purpose [of Apache Wicket] is to make development for Java developers simple as a possible," Dashorst said. "We use a component model for that."Developers can create components with plain old Java and HTML, Dashorst said. Apache Wicket 1.3 is downloadable here.Developing Web applications in Java has been a problem; Apache looks to address this with Wicket, according to Dashorst. "In JSF (JavaServer Faces), for instance, it's fairly hard to create your custom components. You need to have almost a graduate degree to create custom components with JSF," he said.Apache Wicket's lack of reliance on XML is hailed on the project's Web site."With proper mark-up/logic separation, a POJO [Plain Old Java Objects] data model, and a refreshing lack of XML, Apache Wicket makes developing Web apps simple and enjoyable again. Swap the boilerplate, complex debugging and brittle code for powerful, reusable components written with plain Java and HTML," the site said. Wicket emphasizes a logical separation of design and code.A key improvement in version 1.3 is enhanced AJAX support. "Pages can be a lot more dynamic than previously," Dashorst said.Google Guice capability has been added as an alternative to using the Spring Framework with Wicket. Developers also can use Wicket pages directly in a portal without changing a line of code.Also new is the switch to the Apache license over from the Lesser GPL (GNU General Public License). "It's more business friendly," because it allows companies to create closed-source products from Wicket, Dashorst said.A user of Apache Wicket, Nicholas Heudecker, principal at software development firm System Mobile, said his company migrated to Wicket and away from Struts."With Wicket, it's just a lot easier. There's no extraneous configuration. Everything is controlled within the Java code," Heudecker said. "Once people have an opportunity to take a look at it, they'll really like it.?Although pleased with the extra AJAX support and development features in version 1.3, Heudecker added he wished there were better tools support for IDEs. Heudecker said he uses the JetBrains IntelliJ Idea IDE with Wicket but would like more tools.Version 1.3 can scale to very large numbers of users with stateless pages and components. An Apache Velocity template engine in version 1.3 allows for user-generated macros in applications such as a content management system.The logging API in Apache Wicket 1.3 switches from commons-logging to SLF4J (Simple Logging Fa?ade for Java). This bolsters debugging and makes application deployment safer.Although the current version of Wicket is anchored on Java Development Kit 4, the next release in a couple months will be based on Java 5, gaining benefits such as generics to improve safety, Dashorst said.Wicket has been downloaded about 120,000 times since it began three years ago. It was moved over to Apache because of infrastructure issues such as spam and sustaining outages in the Subversion repository at SourceForge, Dashorst said.SourceForge representatives could not be reached for a response.
