• Usability, RIA, and GWT – 6 Questions to Ask your Users | Summa Blog – In conclusion, while definitely not an exhaustive list, I hope these questions at least sparked some thought as to what types of things you’ll want to ask your users and business owners prior to jumping into your GWT code
• Load Testing Relational Databases With JMeter – Apache JMeter is a performance testing tool which is entirely written in Java.

Tate, you’ll go beyond the syntax—and beyond the 20-minute tutorial you’ll find someplace online.

• Java IDEs: the Blue Heeler, the Dachshund and the Labradoodle ~ C for Coding – Java, in my opinion, has the best IDEs of any language or platform bar none. Say what you want about the language but the IDEs are, on the whole, first rate. That doesn’t mean there aren’t bumps along the road however.
• Guice (pronounced ‘juice’) is a lightweight dependency injection framework for Java – Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts
