hi, everybody Again,I got some problems when calling java interpreter and 'appletviewer'. The system shows : $ javac Unable to initialize threads: cannot find class java/lang/Thread $ appletviewer Could not read properties file: /usr/local/jdk117_v1a/bin/../lib/appletviewer.properties I have installed glibc version Jdk117_v1a.i386 on RedHat 5.1. Moreover, is it necessary to install 'Native Thread Class'? Could anybody help me out? Thank you in advance.
