I'm trying to set up an Openfire XMPP server on my MAC, however the problem is that I needed to upgrade to Maverick for Titanium and once you upgrade to Maverick Java updates to a 64bit rather than the 32bit that is needed for Openfire.
How can I get the Java 32bit again?
This Should help you on understanding how to run a 32-Bit java environment with the -d32 switch. However, the most recent version of Openfire should be 64bit compatible, found here.
