Here's a little helpful hint I recently figured out.
I've seen a few people on here ask how they can run their WO
application on Leopard Server with JDK 1.6 instead of the default JDK
1.5. As most people have clearly found out, setting JDK 1.6 as the
default using the Java Preferences applet does nothing for WO
applications launched by wotaskd (which is typically launched by
launchd). The reason is that the Java Preferences applet only adjusts
the default for the current user who is running the applet.
Specifically it modifies the file ~/Library/Preferences/
com.apple.java.JavaPreferences.plist. Unless you happen to be logged
in as the appserver user then this is going to do no good.
BUT, the java launchers (/usr/bin/java for example) will honor the
JAVA_HOME environment variable! The trick is setting the environment
variable it in the right place for launchd.
The easiest way is to set the environment variable for launchd as a
whole. All you need to do is create a file called /etc/launchd.conf
and add the line:
setenv JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/
1.6/Home
Then when you restart the server all Java applications launched by
launchd (such as wotaskd and JavaMonitor) will be launched with JDK 1.6.
If you want to do it just for WebObjects applications launched by
wotaskd then simply modify the launchd script that launches wotask and
add the environment variable there. This page, http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man5/launchd.plist.5.html
, will tell you how.
