java install under redhat 9

xiangshan · 04-09-2004, 06:23 PM

I installed j2sdk 1.4.2 under redhat 9.0 and have some problems.

I use RPM to install it. After intall, I can compile program(it generating .class file), but can not run it.

I checked the install, and found the path of /usr/java/j2sdk1.4.2. But when I run java -version, it displays "1.3.1".

I tried to uninstall the package and it said 1.4.2 is not installed; I tried to reinstall it and it said it is
already installed.

Can anyone help me and explain what is going on there?

Thanks

Hi xiangshan!!!!

Welcome to LinuxQuestions.org. Apparently, your install and compiler works fine. Could you tell us the commands that you are trying to use to compile and run your program?

Thank you for your reply.

I use javac to compile my program, and use java to run my program.

Now what I do not understand is why when I issue the java -version, it gives me the version of "1.3.1", not 1.4.2.
