Unlike the HTTP protocol there's no stable default JMS listener for invoking the Web Services exposed in Apache Axis 1.x using JMS (Java Message Service) as the transport protocol - other than the one provided merely for demo purposes. This article describes a fully working generic JMS listener that can act as a JMS transport receiver handler for Axis and allow service clients to uniquely address individual Web Services in a JMS way and invoke them over JMS. Apache Axis is a popular Java-based Open Source platform for exposing Web Services. It has native support for handling invocations into Web Services based on the SOAP (Simple Object Access Protocol) application protocol. By default, the Axis server supports HTTP as the protocol for transporting the SOAP payload and provides an HTTP transport listener to do the same on its own. The HTTP transport listener accepts...

Developing Rich Client Applications Using Swing - II

In Part 1 of this article, I introduced rich client development, available architectures for developing rich client applications based on the Swing toolkit, and technologies that could be used to make development more productive. In this second part, I'll compare the most popular IDEs and evaluate them with an eye to Swing development for rich client applications. Swing-based Rich Clients: Support for Java IDEs There are many development environments available for the Java platform, each of them provides all sorts of features that can be applied in developing various kinds of Java applications - Web applications, desktop applications, mobile applications, SOA, etc. - and use the various Java distributions - Java EE, Java SE, Java ME. In this article Java IDE evaluation is restricted to rich client application development based on a Swing front-end. Hence in this IDE ... (more)

Oracle Demonstrates WebRTC Solution with CounterPath's Bria

Additionally, Oracle is demonstrating their WebRTC solution and using CounterPath's Bria connecting endpoint. Bria will enable Oracle's Unified Communications Suite to demonstrate its XMPP-based mess... (more)

Steve Riley Of Riverbed Joins Cloud Expo Silicon Valley Faculty

Fundamentally, SDN is still mostly about network plumbing. While plumbing may be useful to tinker with, what you can do with your plumbing is far more intriguing. A rigid interpretation of SDN confines it to Layers 2 and 3, and that's reasonable. But SDN opens opportunities for novel constructions in Layers 4 to 7 that solve real operational problems in data centers. "Data center," in fact, might become anachronistic - data is everywhere, constantly on the move, seemingly always overflowing. Networks move data, but not all networks are suitable for all data. In his session at 15th Cloud Expo, Steve Riley, Technical Leader in the Office of the CTO at Riverbed Technology, will discuss how finding (or building) the right network, with the right applications, is still a labor-intensive task. Must it always be this way? No: for networks will soon be expressed as code.... (more)

Working with Swing

One of the strengths of Java is the abundance of standard APIs for doing everything from enterprise-level data access to manipulating data structures, sending and receiving e-mail and building GUIs. This broad sweep of APIs makes choosing how to implement the various parts of an application much simpler, but it also presents a problem: How do you best use the API? Javadocs – the raw API documentation – are never enough for this purpose because they concentrate on each class or interface as a separate entity from the other classes. API specifications aren't much better because they deal with the minutiae of the API and with being a correct specification of how everything works. The most useful tool I've found for any newcomer to an API is the Java Tutorials (www.java.sun.com/docs/books/tutorial/index.html). These Tutorials guide you to correct and efficient use of an ...

Best Practices for JDBC Programming

As a consultant, developer and database administrator, I've often been asked to provide coding guidelines and tuning assistance for Java code that utilizes JDBC. Over time, I've been introduced to or developed standard coding practices that make JDBC code faster and less error-prone, and easier to read, understand and use. This article documents some of the more important "best practices" for using JDBC libraries to perform database access. As most of my clients are using Oracle database technologies, I've included several practices that are Oracle-specific. For the purposes of this article the goals of best practices for JDBC programming are maintainability, portability and performance. Maintainability refers to the ease with which developers can understand, debug and modify JDBC code that they didn't write. Portability refers to the ease with which JDBC code can ... (more)

Trimming the Fat from Swing

I'm sure we've all heard it before: Java on the client is slow; Swing is slow. The reality is that Sun has made great progress in increasing the speed of Swing and Java on the client. However, it's up to developers to demonstrate that Java has indeed improved to the point of usability and viability on the client. To do this, the code needs to be very lean and clean. One of the original problems with GUI creation was the reliance upon Visual Development Tools to design and code the GUI. While these VDTs have come a long way in the last few years, I have found that many developers rely so heavily on the VDTs that they've gotten lazy when it comes to coding the actual functionality of the application. The Problem Methods are expensive in terms of execution time. The more method calls made, the slower the application will be. However, there needs to be a balance betwee... (more)

Are You Using Abstract Classes, Polymorphism, and Interfaces?

If the answer is no, at a minimum your project needs a code review. Let's work on the following assignment: a company has employees and consultants. Design classes with and without the use of inheritance to represent the people who work for this company. The classes should have the following methods:   changeAddress promote giveDayOff raiseSalary Promotion means giving one day off and raising the salary by a specified percentage. For employees, the method raiseSalary should raise the yearly salary and, for consultants, it should increase their hourly rate. Abstract Classes A class is called abstract if it has at least one abstract (not implemented) method. The keyword abstract has to be placed in the definition of the method(s) and the class itself. For example, the class in Listing 1 has three concrete methods and one abstract. (The link to the source code is availab... (more)

Where Is i-Technology Going in 2004?

Read this Article in .PDF Format Read JDJ's Exclusive Interview with Alfred Chuang Read Scott McNealy's 2004 Predictions Read From the Publisher... "Some of the remaining visionary talent at Sun will finally become so frustrated with the company's handling of Java that they will quit in disgust." - Rick Ross, Founder & CEO Javalobby "So where is it all going?" It's the question every technology sage is always asked, and yet, of course, it's the question that's the most difficult to answer. Here at JDJ we decided nonetheless to ask a welter of the brightest and most prescient i-technology professionals what they are seeing, what they think the individual pieces in 2004 are, and how those pieces fit into the bigger picture. Java features prominently, Web services (and associated technologies) looms large, and SOAs (service-oriented architectures) make their debut, bui... (more)
