J2EE

Few weeks ago, a new “awesome” feature made appearence in the GlassFish Milestone 1. This feature, the “Application versioning”, aims to help you deal with the multiple versions of your Java EE applications in a simple and easy way with the usual GlassFish administration commands. This feature allows users to deploy multiple versions of the same application in a GlassFish...

I have been a Java developer since the 1.02 days. It has been a long and fun ride, and in spite of what people said over the years, the Java language and Java platform didn't die and are in fact stronger than ever. But sometimes I wish it would evolve faster. Java EE has come a long way, to the point  Java EE 6 can be considered a lightweight development platform. When Glassfish v3 was...

One of the features that had been lacking in JSF has been the ability to use the JSR 330 @Inject annotation for injecting object instances into JSF managed beans.  The feature now has been enabled in GlassFish 3.1 - starting with the latest July 22 nightly builds, or a current source build.  So now, you should be able to use it in a JSF managed bean as follows: import javax.inject....

Btrace is a wonderful tool for debugging complex application problems. I have used it recently to debug a strange finalizer problem in an application running on Glassfish V3. Since getting it to work with v3 wasn't very straightforward, I will share my findings here in case someone else is trying to do the same... BTrace works as a JVM Agent, which means it gets the chance to modify classes...

One of the main features in GlassFish 3.1 is clustering and for m2 we have added support for creating and starting instances on remote hosts.  The underying GlassFish 3.1 code uses SSH to connect to the remote hosts and introduces the concept of a node which is used by the system to deterimine where the instances will be created or started. At this time the only connection type supported is...

EJB

The Enterprise Architectures for Java EE Weighting Survey ends this Friday, June 25. Kate Jones of Oracle recently talked about the survey and its purpose: We are looking to make improvements to our Java Enterprise Architect course and certification to support Java EE 6. The result of this survey will allow us to better align our Java EE architect course and certification with the role of the...

Databases

In my opinion, SQL Anyhwere is the best RDBMS I can think of. I can remember when we started distributing it in Germany back in the early 1990ies, as one of the first early adopters in this country. Since then, we provided it to hundreds of enterprises, from single-person laptop-only ones to large ones spanning replicated installations crossing country borders. So call me biased in that...
