Jakarta's Digester maps data from an XML source to Java objects. Learn all about this package and its advantages over other similar APIs. Then follow a real life Digester parsing example.

The Internet has no doubt become the most popular source of information today. More and more businesses have adopted the Internet as the vehicle to display their business information, advertise their products, and maintain customer interactions. The activity of developing Web applications occupies a fair amount of resources, time, and effort.

Joe Walnes's XStream is a unique open-source Java library for serializing objects into XML and deserializing that XML into objects. Unlike other APIs, such as David Megginson's XMLWriter or Elliotte Rusty Harold's XOM, which use specific classes and methods to produce XML, XStream relies on Java idioms such as object names to produce element names and strings within classes to produce element content. It also produces a kind of reflection of objects in XML.

Borland Software Corp. has announced the imminent release of the latest version of its JBuilder IDE. What would have been JBuilder 10 will be known as JBuilder 2005, beginning a new naming convention for the popular Java IDE, which is scheduled to ship in September.

Sybase announced Monday the availability of PowerBuilder Enterprise 10.0, a new version of the company's rapid application development (RAD) tool that adds support for J2EE and Microsoft .Net.

The big story in app development for the past few years has been the competition between Microsoft’s .NET Framework and products that support the J2EE specs. Lots of people have talked about it, and many development organizations have been faced with this issue. To a large extent, the .NET vs. J2EE struggle has defined the recent app development landscape.

With demand for Microsoft SQL Server connectivity for Java applications growing steadily, and with many companies migrating their production platform from the 32-bit SQL Server 200 Enterprise Edition to the 64-bit versions of SQL Server 2000 and SQL Server 2005, JNetDirect has added 64-bit support to two of its components.

The previous installments of this column gave you a thorough overview of JAXB, so you're now ready to study varying data binding implementations. This article begins an in-depth look at JaxMe, an open source implementation of JAXB. In addition to offering several enhancements to the basic JAXB specification, JaxMe offers integration with databases and Enterprise JavaBeans, both significant extensions to basic data binding behavior.

As the message of Java's robust health permeated the 2004 JavaOne Developer conference, an underlying message became clear: The opportunities for Java developer entrepreneurship are also alive and well.

Sun Microsystems held it's annual JavaOne conference in San Francisco this year. There was a great turnout and many announcements made during the first two days. For details on each announcement Sun has set up a nice JavaOne website to link you to more detailed information.

In a previous article (XML Basics Part One);we had a brief look at XML. However, as stated in the article, XML itself is worth nothing without the set of APIs that are generated-it would simply be just another fancy form of CSV, that is, a proprietary data format! My aim in this set of articles is not to actually reveal XML in its every detail, but rather have a look at the implications of XML in today’s technologies. That’s why the previous article only sheds a little light into the insights of XML, which included some terms and technologies you will be confronted with the moment you step in the XML arena.

Last time, we learned about JAXP, Xerces, DOM and the javax.xml.parsers Java Package. How about getting a little taste of the SAX interfaces? We look at available classes and interfaces, and learn how to use SAX for XML Processing. Given SAX's power, perhaps we can look forward to the day when we'll be translating not just XML, but maybe even Klingon! Maybe not. Before you get started, you'll want to download the support files for this tutorial.

So far, during this series of articles (part 1, part 2) we've looked at DOM and SAX, and I suppose most of you are thinking which one of the two approaches is preferable? Well, there is no general rule of thumb, but this article might help you make the right decision when you’ll have to.

In the previous lesson entitled Java JAXP, Implementing Default XSLT Behavior in Java , I explained default XSLT behavior, and showed you how to write Java code that mimics default XSLT behavior. The Java program named Dom11 that I developed in that lesson serves as a skeleton for more advanced transformation programs. This lesson updates Dom11 into a new program that tests and exercises several methods that were not tested by the samples used in the previous lesson.

Sun Microsystems continued to place its focus on appealing to the developer community with a recent upgrade to its Java Web Services Development Pack 1.4. The company also announced a new edition of the Sun Java System Application Server 7 for its Java 2 Enterprise Edition (J2EE), which is available in a free download.

Sometimes you just wish software architects weren't so creative or, at least, were more coordinated. It seems that's what happened with SOAP, the standard format for web services messages. The SOAP specification started out defining a lot of protocol-specific XML structures that now, in hindsight, could obviously better be delegated to the W3C XML Schema language, the whole purpose of which is to define the structure of XML documents. It's a disconnect that the Java community is still working out.

Sun Microsystems last week marked the advent of Version 1.4 of Java 2 Enterprise Edition (J2EE) at a press event in San Francisco that featured most of the big names in Java tools and application servers. A tools panel included representatives from Borland, BEA, IBM, Oracle and Sun, who shared the stage and discussed the impact of J2EE 1.4 from a tooling perspective, and speculated on emerging trends in the tools market. Additions to J2EE 1.4 include improvements in Web services support.

VM Tools is the beginning of a collection of XML-oriented tools for the java platform. The toolkit is developed by VM Systems, Inc. and is available under an open source license.

As the name implies, the Java API for XML Processing (JAXP) is an API provided by Sun designed to help you write programs for processing XML documents. JAXP is very important for many reasons, not the least of which is the fact that it is a critical part of the Java Web Services Developer Pack (Java WSDP).

Remember Napster, Gnutella, and SETI@home? Those Web-based, peer-to-peer (P2P) implementations were and are extremely popular, building open peer groups of millions of connected devices. Now the extension of P2P into the mobile environment is a given, considering the explosive growth of mobile devices and networks around the globe.
