Windows 2003 Cluster & WLS

Hi -

We are configuring a new clustered environment and moving forward with
a Windows 2003 Enterprise Edition Microsoft Cluster. I have scoured
the web and BEA's forums, but I see no information about what we will
need to do to load our application and configure WLS to take advantage
of this environment.

We have two machines OS-clustered together that share an external hard
drive. I intend to install WLS on both machines and setup a WLS
cluster. Does this make sense to you, and has anyone done this before?
I'm trying to identify the gotchas prior to stepping into the data
center.

Thanks!
Josh
