From SOA World Conference & Expo 2005 East (April 17, 2005) - This month's Web Services Edge Conference -SOA World Conference & Expo- marks four years since the first detailed W3C note on the Web Services Definition Language (WSDL) and nearly five years since the first public specification of SOAP. You may be wondering, why hasn't the uptake of Web services matched the bold predictions made when it was first launched? There are certainly more developers thinking about Web services with the advent of service-oriented architectures (SOA). However, the number of successful public Web services projects seems to be limited to a few high-profile companies like eBay and Amazon that have published APIs and end points, or developers who have been able to implement services internally but with a narrow and well-defined set of services - still a long way from the smart applica...

Calvin Austin's Java Blog: "Go Geronimo Go!"

Go Geronimo Go!Posted by calvinaustin on January 09, 2006 at 11:10 AM | Comments (0) Geronimo 1.0 was released last week. Apache Geronimo is a new, open source, J2EE 1.4 certified application server. It is built from many established open source projects, like OpenEJB, Tomcat and the Derby database so it already has some pedigree. The more I think about it, Java developers are in a great position. There is a great choice of open source J2EE app servers, Geronimo, Jonas, JBoss, Glassfish or you get free access to many commercial servers. If you are interested in trying out Geronim... (more)

What Does the Java Future Hold?

Last month I took a trip down memory lane, revisiting the history of J2SE. Apart from trying to remember key events, squeezing 10 years of history into one page was a challenge. I had to relegate many significant technologies to a sentence or two and some I didn't cover at all. However, looking at the future of Java is like looking at NASA's Apollo plans after the first walk on the moon. Yes, there will be valuable missions or releases, but even NASA canceled the last three moon missions due to budget issues. The good news is that mission control has already have scoped out the 6....

JAVA Technology on the Linux Platform

The Java 2 Platform, Standard Edition (J2SE technology) v1.3 for Linux means that Linux users and developers can take advantage of thousands of Java technology-based applications, from enterprise e-commerce infrastructure to client-side applications. It also opens up a huge emerging market for companies that already develop Java products. The Java 2 Platform port was developed with the assistance of the blackdown.org porting group. Although Linux is a UNIX-based operating system, it's evolved at a different pace and direction than other UNIX platforms, making a port of the Java ... (more)

Under the Hood of a J2EE Application Server

I recently had the opportunity to talk with many Java users about the current release and their general experiences with the platform. One of those developers told me that he didn't use J2SE but his J2EE VM sometimes caused problems. Now most of you know that there is no such thing as a J2EE JVM. From my own experience with J2EE application servers, many do a good job hiding this from you. It can be difficult to work out which version of J2SE you are using, let alone know that J2SE is behind the scenes. In this issue we are focusing on J2EE. If you are a core J2SE developer, th...
