Ship Happens! Insights From the Eclipse SWT Community

The Standard Widget Toolkit (SWT) is the GUI toolkit used by Eclipse. The same folks that worked on the Common Widget (CW) library for IBM/Smalltalk developed it, this time for Java. Now, it's maintained as part of the Eclipse Platform project and distributed under an open source license, the Eclipse Public License (EPL). One key design point of SWT is that it uses native functionality on each operating system and, at the same time, presents a common, portable API. Joe Winchester, Desktop Java Editor for Java Developer's Journal, asked Steve Northover (SWT Team Lead) recently whether he'd be happy to answer some questions about SWT and, after talking to his colleagues and a few developers, here is the result. JDJ: SWT supports many different widget toolkits with a common programming API. What's the hardest thing about making all this work? Steve: Specifying an API t... (more)

AjaxWord: An Open Source Web Word Processor

AjaxWord ( is an open source Web-based word processor. It closely mimics Microsoft Word in both look-and-feel and functionality. The application was initially written between 1997 and 1999 using JavaScript/DHTML on the client side with ASP on the server side. It was released on the Web in 2000. In 2005, the application's server-side logic was migrated to Java and released as open source code. On the client side, the application looks and feels like a typical desktop application, e.g., Microsoft Word. The design features the kind of rich graphical user interface that Microsoft Word users are familiar with, such as hierarchical menus, toolbars, wizards, file dialogs, and a multiple document interface (MDI). (Figure 1) On the server side, the application is a typical Java-based Web application. It features: User authentication and authorization. User-... (more)

Java Feature — Using the Java Persistence API (JPA) with Spring 2.0

The EJB 3.0 Java Persistence API (JPA) was released in May 2006 as part of the Java Enterprise Edition 5 (Java EE) platform, and it has already garnered a great deal of attention and praise. What began as merely an easier-to-use successor to the much-maligned container-managed persistence (CMP) portion of the EJB component standard soon evolved into a full-blown incorporation of the existing best practices of the most prominent and popular object-relational (O-R) persistence products in use. The result is that applications now have a modern standard for lightweight enterprise Java persistence that they can use in any compliant Java EE 5 application server, or in Java Standard Edition (SE) applications. The Spring application framework has been in existence for four years, and it has become a popular choice both in an application server context and standalone. Like ... (more)

Open Source and the Flash Platform: What Should Adobe Do Next?

Open source must in some way present itself as a bit of a dichotomy to Adobe, now that it has acquired Macromedia. It is generally accepted that open source solutions foster innovation and adoption. However, with an open file format and a free player, is it possible that some projects could eventually challenge Flash's own role by creating competing tools? Jim Phelan writes: In a major repositioning effort in June of 2005, Macromedia - now Adobe - unveiled the "Flash Platform." The conception of Flash, the company had decided, needed to change: Flash had evolved from a tool for designers to an interoperating set of technologies appropriate for web application development. The time had come to abandon Flash's winsome singularity and start talking in terms of solutions rather than products. The OSFlash Initiative Around the same time, a group of developers was working t... (more)

Open Source AJAX Enabled Framework for Building Customized User Interfaces for JMX

The first release of ajax4jmx has been announced. Ajax4Jmx is claimed to be the first open source AJAX enabled framework for building customized user interfaces for JMX. This is a framework for building customized dynamic web interfaces for JMX applications. Java Management Extensions (JMX) technology provides the tools for building distributed, Web-based, modular and dynamic solutions for managing and monitoring devices, applications, and service-driven networks. By design, this standard is suitable for adapting legacy systems, implementing new management and monitoring solutions, and plugging into those of the future. ajax4jmx currently provides a simple JMX browser, as well as JMX components for use in other applications. It is implemented using GWT, Google's Widget Toolkit. It includes general purpose widgets such as dynamic editable tables supporting multiple sel... (more)

Developing an Application Using the Eclipse BIRT Report Engine API

The Eclipse platform is an open source, integrated system of application development tools that you implement and extend using a plug-in interface. The Eclipse Business Intelligence Reporting Tool (BIRT) is a set of plug-in extensions that enable a developer to add reporting functionality to an application. BIRT provides a Report Engine API that a developer can use to create a customized report generator application. The package contains a set of interfaces and implementation classes that supports integrating the runtime part of BIRT into an application. The BIRT Report Engine can provide report generation and rendering services in the following environments: Stand-alone engine: A Java developer uses a stand-alone engine to render a BIRT report from a report design (.rptdesign) file. In this environment, the Java developer create... (more)

Creating a Common Cloud Computing Reference API - Part One

Reuven Cohen's "ElasticVapor" Blog Over the last few weeks I've been engaged in several conversations about the need for a common, interoperable and open set of cloud computing standards. During these conversations a recurring theme has started to emerge. A need for cloud interoperability or the ability for diverse cloud systems and organizations to work together in a common way. In my discussion yesterday with Rich Wolski of the Eucalyptus project he described the need for a "CloudVirt" API similar to that of the Libvirt project for virtualization. For those of you that don't know about libvirt, it's an open source toolkit which enables a common API interaction with the virtualization capabilities of recent versions of Linux (and other OSes). I would like to take this opportunity to share my ideas as well as get some feedback on some of the key points I see for the cre... (more)

President & CTO of 3tera Speaking Next Week at SYS-CON's Cloud Computing Expo November 19-21 in Silicon Valley

The 3tera Blog Months ago, 3tera unveiled our Cloudware architecture. But rather than try to convince the world that there is only a single architecture that works and ours is it, we emphasized that Cloud architectures need to be open. Not only need they interoperate with all sorts of hardware and software as virtual appliances, they need to interoperate with other Clouds and Cloud components as well. Now, of course, the two undisputed leaders in virtualization, VMWare and Citrix/Xen, have both announced suites of products in support of Cloud Computing - vCloud and Citrix Cloud Center (C3), respectively. Undoubtedly, Microsoft and Red Hat and more will follow. The anticipation that drove our Cloudware architecture is proving spot on. There will be multiple global Clouds, they will not all be the same, and the ones that will get the brass rings will be the ones that ... (more)

Bad File Descriptor Error in Linux

In a Linux system, files, blocks, directories, sockets and other items are referred by corresponding file descriptors. If your system is reporting errors that the file descriptor is bad, one of possible causes is that file system is corrupt and thus, you require restoring from backup. But if backup is not valid enough to restore complete information, you need to use advanced Linux Data Recovery applications. As an instance, you might encounter the below error message with your Linux based system: “Bad file descriptor” You might receive this error while trying to access a file or while trying to boot the system. Cause Possible reasons for the ‘Bad file descriptor’ error to occur are: Linux systems use a special file, called /dev/null (also called the null device). This file removes all the data that is written to it after reporting that the write process has succes... (more)
