for me I will answer this question based on my experience.

so if I'm gonna start new project I will use the following technologies:

  1. AndroMDA as MDA framework.
  2. Spring (DI, Interceptors, Quartz, ACEGI, ... etc).
  3. Hibernate.
  4. JSF.

off course you might need to play with some helper frameworks/libraries such as:

  1. Velocity.
  2. CAS; if you need SSO.
  3. JXLs; if you need small and easy library for generating Excel files using XLS templates.
  4. Drools; which is Artificial Intelligence a Rule Engine that uses the Rule Based approached to implement an Expert System and is more correctly classified as a Production Rule System.

in terms of testing I will consider the following frameworks:

  1. TestNG; you may want to use JUnit in the part of Unit Testing but TestNG is more than a unite testing framework;
  2. WATIR or SELENIUM as web testing;

Can anybody else suggest other options?

java frameworks
