I haven't used either of those applications, but I've run similar programs and servers (e.g. Tomcat and PostgreSQL) on much less powerful machines without difficulty. [ February 17, 2005: Message edited by: Bear Bibeault ]
I guess we live on different worlds. No one I know would touch Weblogic.
In any case, my point was not to try to get you to use different apps, but to point out that similar apps run just fine on a much less powerful machine. Which leads me to believe that you wouldn't have any issues running the apps of your choice on your, more powerful, machine.
