Eclipse seems intelligent enough to really follow Java naming conventions

I'm very sensitive on how I know my variables when I program and the most I'm very careful with is naming boolean variables. So I was trying to create a new variable inside of Eclipse and I'm not used to naming my boolean vars like isNew,...

JUnit with Netbeans

Annoying requirement for an EJB Session Bean method

I'm a bit irritated about Session Beans because I have to implement the Serializable interface for every object that I pass to a Remote method. Of course, it totally makes sense to do that when you're making remote invocation but I'm thinking...
