MyBatis (formerly called iBatis) – Examples and Hints using SELECT, INSERT and UPDATE Annotations

MyBatis (http://www.mybatis.org/) is a lightweight persistence framework for Java and .NET. This blog entry addresses the Java side. MyBatis is an alternative positioned somewhere between plain JDBC and ORM frameworks (e.g. EclipseLink or Hibernate). MyBatis usually uses XML, but it also supports annotations since version 3.

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

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.
