installation problems

[Meng Shen]

Hi,

I am pretty new to java and linux.  I need your help on the following
problem.
after extracting "jdk_1_1_6-v5-libc5-x86_tar.gz" to one directory, I
run "java".

I got the error message like the following:

...Checkversions: {isGreaterOrEqual: command not found
..bin/i586/green_threads/java: can't load library 'libXp.so.6'.

The Linux version is Redhat 4.2. Kernel is 2.0.30

How to fix this problem quickly? I mean I can do it without upgrading
the
whole OS.

Thanks
