This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Struts 2 has a doubleselect tag. If you aren't maintaining legacy code, I'd recommend you use Struts 2. It is much easier to work with than Struts 1.x.
