Hi, Today I tried to install oracle8i on my Potato box with glibc upgraded and jdk1.1 from unstable. The installer program failed to invoke the 'dbassist', when i run it from command line, jre said: Unable to initialize threads: cannot find class java/lang/Thread Could not create Java VM So i wrote a "Hello,world" java program, jre gives the same error message but "java" works. Any suggestion? Thx. (Sorry, I know little about java)
