The Java Development Environment
Well, you can call me nostalgic, but I really miss it 
What I miss in Java development environment is a tool or a set of tools that makes easy to develop and provide a good workbench for developers, just like the old Delphi or nowadays Visual Studio .NET.
Just to clarify I am not an IDE addicted and I like to perform some manual tunnings in the application as well, but as JEE development gets more complex, like using Spring, Hibernate, EJB 3, WebServices, JSF, and a huge stack of frameworks sometimes it’s difficult to get everything configured, setup, tested and validated quickly.
There are plugins for eclipse, IntelliJ that helps a lot, and NetBeans is doing a great job on this direction trying to build a unified environment ( NetBeans IDE + GlassFish + Frameworks support and so on ) to help developers to have a more consistent environment.
One hard to goal to achieve to bring a good level of productivity to the development team with the tools they are using, I mean, we always have to use lots of things, such as eclipse, maven, and so on, and sometimes the time spent struggling to some problem because they don’t have the right tool. But, I am confident we are getting better with out tools.
