ColdFusion installation on Oracle WebLogic is supported, and 64-bit support is also available.
Per Adobe, following are some points to note about this setup: The majority of the functionality and features of ColdFusion run on 64-bit platforms; however, certain features including ColdFusion COM interoperability, ColdFusion Delphi interoperability, and Microsoft Access database connectivity do not work on a ColdFusion 64-bit platform. A few other features, such as ColdFusion .NET integration services and database drivers currently run in 32-bit mode.
If we get some time, we’ll try to post detailed install instructions as well. Check back and/or contact us if this would be on particular interest to you.
