Report: One-Day Conference “DOAG SIG Java 2010″ about Java Enterprise Edition 6 (JEE 6)

Posted in Application Server, ESB, IT Conferences, Java / JEE on September 9th, 2010 by Kai Wähner

Today, I visited the one-day conference “DOAG SIG Java”. The main subject was the Java Enterprise Edition 6 (JEE 6).

I presented about applicability and limits of Java Server Faces 2.0 (JSF 2.0). You can download my (german) presentation slides:  DOAG SIG Java (Sept2010) – Einsatz und und Grenzen von Java Server Faces 2.0

“DOAG SIG Java” – What’s that?

The DOAG is a very large, german, independent Oracle-Usergroup. After the acqisition of Sun, the SIG Java was established to demarcate the Java technology from other business units (database, administration, …). Conferences are organized several times a year, the number of participants varies from 50 to 2000.

JEE Development using JRebel with IBM WebSphere (WAS) 6.1 and RAD 7.0

Posted in Application Server, Java / JEE on August 14th, 2010 by Kai Wähner

JEE Development using JRebel with IBM WebSphere (WAS) 6.1 and RAD 7.0

I want to share my experiences with JRebel (http://www.zeroturnaround.com/jrebel/). If you need some neutral information about this product to ease development with J2EE / JEE applications and application servers, this blog entry is for you!

Problems with JEE Application Servers

If you develop with WAS, no matter if it is version 5 / 6 / 6.1 / 7, deployment takes a very long time. Even changing a single line of code (e.g. to add a System.out.println) takes about 15 minutes in our project for publishing the changes, because you always have to do a build and redeployment. So, sometimes you have to wait 50 percent of your working time until WebSphere is ready again.
