| Running BlueJ with Java 5 on Mac OS
X
Java 5 is supported on Mac OS X only on system 10.4 (Tiger).
It does not run on earlier version of Mac OS X. If you are running
Mac OS X 10.3 or earlier, you're out of luck.
Java 5 is not included in the standard installation of Tiger,
so you have to download and install it separately. When you do,
it is installed alongside JDK 1.4.2, leaving 1.4.2 the
default Java version. Since BlueJ uses the Java version declared
as the default by the user, you need to make Java 5 the default
to get BlueJ to use it.
1. Get Java 5.
Downoad Java 5 for Tiger from
Apple. Install it in the usual way.
2. Make Java 5 the default
The Java 5 installer adds a new utility to your system, called
'Java Preferences'. It is in /Applications/Utilities/Java/J2SE
5.0/Java Preferences.
Start this utility. In the section titled Java Application
Runtime Settings, drag J2SE 5.0 to the top of the list
of supported versions. Save, and you're done.
BlueJ now uses Java 5. You can, of course, reverse your choice
in the same way.
