How can I downgrade from Java 7 to Java 6 in Lion? 


I have a web-based application that I use regularly for work (Cisco's Adaptive Security Device Manager (ASDM)), which worked fine under Java 1.6, but will not run under Java 7.  I mistakenly upgraded to Java 7 a few days ago, and now when I attempt to launch ASDM, the Java 7 splash screen comes up and never goes away unless I quit the ASDM instance.


I've looked at several support forum postings, and most reference a "Java Preferences" utility that does not appear to be on my system.  I do have Java installed, and the output of "java -version" from a terminal window even shows some Java 1.6 installations.


discard:~ streiner$ java -version

java version "1.6.0_37"

Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)


Checking says I have Java 7, Update 9 installed.  The behavior of ASDM when launched from a browser (Firefox) shows that it's trying to use Java 7.


Not sure why there is a discrepancy here.


For now, I'd like to just wipe out Java 7 if that's possible.  If not, I'd like to force all applications to use Java 6.  The only thing I run regularly, that I know of, that requires Java is ASDM.  From what I can determine from Cisco, Java 7 might be supported in a futue version of ASDM.  Their recommended workaround for now is to use Java 6.


I'm looking for recommendations on the best way to proceed here.  Until Java 7 is supported in ASDM, it is of no use to me.


Thanks in advance
