Despite being a Ruby shop, we do have our hands in some Java issues...
Ask for Help
"Anyone know of a good Rhino Javascript book?" (He was looking for more information on the Javascript implementation using Java and related information)
Nope :(.
"What is the status of finding out how to sandbox Java"
Still in progress.
Interesting
Changing the Java version from 1.5 to 1.6 in Mac OSX is painful.
It may be tempting to manually install Java and then just change the link (in some file called "a"), but this is wrong and spits out warnings.
Most options can be set using:
/Applications/Utilities/Java\ Preferences.app/Contents/MacOS/Java\ Preferences
and then setting $JAVA_HOME is up to you.
- Arun Gupta seems to have documented more of the process for more reading and installation details.
