Do you guys have any tips on being able to switch between java versions,
namely 1.6 to 1.7?
I remember seeing a nice bash script that did this, it actually listed
all
the javaverions installed and let you choose which one to be active.
if you’re on OS X there’s java_home:
JAVA_HOME=$(/usr/libexec/java_home -v 1.6)
run /usr/libexec/java_home -V and it lists all installed versions.
besides filtering on version (with -v as above) you can filter 32 bit
vs.
64 bit and you can even use it to execute a specific version of java:
/usr/libexec/java_home -v 1.6 --exec java -version
T#
Also for OS X is “pickjdk”, a bit richer than java_home:
This is what I use, and I think it’s the one the OP was looking for
(presents a menu, etc).

Hah…yeah perhaps it could be Ruby, but I don’t know if Ruby can
manipulate calling shell’s env 
Anyway, there it is!

Charlie -
What weird language is that in, and how come it’s not Ruby?
I respect the ability to write nontrivial shell scripts, but boy, that
code
is ugly!
In any case, thank you, Nick, for writing it.
