Installing JPL

HI all,

I installed Perl5.6.1,JPL-08201999 and jdk1.3.0 on RedHatLinux7.0.J
(Kernel2.2.16-22 on an i686).
I have been trying to install JPL to call perl from java for a few days.
but,I had the following error message and I can't run Sample program with
JPL.
If any one knows what's causing the error, please help me.
Thanks,
