"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'd go with Citrix. Application servers and VMware do not wark all that well and take a lot of tweaking
Not sure I understand the question -- can you clarify?  
Citrix is generally used to deliver applications in a Terminal Services type of delivery.  So in its most basic form, using Citrix is like using Remote Desktop:  Users are just remote contolling a session on a computer that has the application they need installed on it.  Citrix can be done in a "Published desktop" type format so that it feels just like using Remote Desktop, or it can be done in a Published Application type format so that you have icons to click to launch individula applications, which are still just Terminal sessions on a remote computer.  Citrix can be installed ona standard server or on a VM server after first installing W2K3 with Terminal Services.
Not sure what your other VM route would be -- can you clarify what that route would be?

The question shouldn't be Citrix vs VMWare as they are two different technologies, (Application delivery vs Virtualisation).

I guess you're talking about server side processing (Citrix/TS) vs client side processing (Oracle VM/Java VM). It all depends on the application you are talking about. Please specify more.

Good enough for the time being.
Thank you.
As this is a most-viewed answer right now, I have to make a comment to dmbgo's answer: as a developer, I have been using VMware for separating development environments for years.

I have not run across any app server that didn't work with any VMware-hosted OS (including a variety of windows and linux OSs). Specifically, the following have been used: Weblogic, Websphere, Jboss, & tomcat.

On VMware ESX & Workstation.
