For me PrimeFaces is a great component set for JSF 2.0. I's fresh and has no JSF 1.0 history. It has everything I need to build enterprise applications. For me it is a great compromise between full component-style framework like Vaadin and lightweigh MVC-like web frameworks. I've bult several applications with PrimeFaces and I am sure I'd never built it so fast with any other framework.

Eclipse is one of the most commonly used IDEs. It is a platform with loads of plugins. Be sure that you'll spent a lot of time configuring it. There is no way to use it effectively without understaing lots of setting options. Nothing is simple. However it is worth learning. As a developer you'd probably use it 8 hours a day so spending several hours on customisation might pay off. One yo've learned it you'd be able to create software very quickly and effectively. For me it is the best free IDE, but definetlny not the simplest. It is much better now with Eclipse Market.

Vaadin is a good web framework. You don't need to think about HTML and JS. You build your apps like in Swing. However there are several drawbacks.

  • Generated HTML and JS code is quite heavy for complex UIs. I ended up with changing some components to HTML labels and writing HTML by myself because of poor application performance. Application worked ok on Opera nad Chrome but Firefox was slowing down.
  • Creating new components is quite hard. You have to recompile GWT widgetsets etc.
  • You won't have a save-and-refresh workflow like with JSF or Tapestry.

But still Vaadin is one of the best component-based web framework along with ZK and GWT.

This is the greatest tool for application monitoring I've ever used. It is much simpler (and cheaper) than AppDynamics, NewRelic or dynaTrace. Finding bottlenecks takes just minutes. It also has a JMX management and you can expose values monitoring via HTTP. Just plug it in to you Nagios to alert you while performance is dropping.

The community is not wide but helpful.
