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.
No version of WebLogic is certified by BEA to run on Windows 9x. However, that does not mean that it will not run.
