On Solaris, set the locale to en_US. E.g., in the login screen, select en_US from the language menu. Execute the following commands (using bash, or use different syntax for other shells) and see what happens:

$ export JDK_HOME=/usr/local/java/jdk1.2_ea2/solaris
$ /usr/local/java/hjb1.0.1/solaris/bin/hotjava
HOTJAVA_HOME is set to /usr/local/java/hjb1.1/solaris
