Officially Weblogic is supported on Suse and RedHat only. Not on Ubuntu. But installing it on Ubuntu (Edgy) was smooth. Just downloaded the Weblogic Server 9.2 Redhat x86 installer and executed it. Installation went fine without any problem. After installing I was searching for the menu item for the config wizard. Its not added. So have to manually add it. Same for the menu item for starting generated domain servers. Otherwise the I thought its going to be a painful experience, but overall it was smooth!
