Hi all,

I have two environment base on following Linux operating systems, and the JDK version are same as j2sdk1.4.2_12, and locale are also same as en_US.UTF-8.

Linux server1 2.6.9-22.ELsmp #1 SMP Mon Sep 19 18:32:14 EDT 2005 i686 i686 i386 GNU/Linux
Linux server2 2.6.9-42.0.3.ELsmp #1 SMP Mon Sep 25 17:28:02 EDT 2006 i686 i686 i386 GNU/Linux

My problem is the resources sorting in CLASSPATH are different in preceding two operating systems. Here is the sample.

Server 1: CLASSPATH=../../a/PbcSrc.zip:../../a/Pbc.jar
Server 2: CLASSPATH=../../a/Pbc.jar:../../a/PbcSrc.zip

Since the only difference of two environment is the kernel version, does it influence the sorting of resources in CLASSPATH?


Best regards,
Leon

The CLASSPATH is an environment variable that you set yourself somewhere, in a configuration file or startup or login script. The system does not automatically set it for you. The Linux kernel does not have anything to do with your CLASSPATH.

You must have slightly different configuration / startup / login scripts on the two systems somewhere.

By the way, it's not a good idea to write Java programs that rely on the fact that things in the CLASSPATH are in a certain order - it makes your program very susceptible to small system configuration changes.

It is sorta covered in the JavaRanch Style Guide.
