upgrading java on red hat 9
I'm sort of new to linux and am having problem with java.
I just installed Red Hat 9. It came with java1.3.1 I think. I wanted to upgrade this so I downloaded 1.4.1_03. I just downloaded the jre, not the sdk. I followed some HOW-TO's to install it.
It was all installed into /usr/java/j2re1.4.1_03/
When I did java -version I still got the 1.3.1.
So i noticed there was a /java directory on the root and I turned the /java directory into the j2re1.4.1_03 directory. So now the /java directory has the same structure as the j2re1.4.1_03 directory. This did not help my version. However, when I called the whole path it was the right version, ie /java/bin/java -version it came up correctly with version 1.4.1. So I continued looking.
I also set my environment variables by creating /etc/profile.d/java.sh
This file contains
I found that /usr/bin/java -version was 1.3.1. This was the only place I found 1.3.1 instead of 1.4.1. I thought it would be a good idea to
cp /java/bin/java /usr/bin/java and overide the current java in the /usr/bin so that when I went /usr/bin/java -version I would get 1.4.1
The result was not that at all. Instead I got errors "can't find libjava.so" "can't find java 2 runtime environment".
I've been trying to fix this problem for about a day now. I uninstalled the 1.4.1 package and put back on 1.3.1_08 and recopied the /usr/bin/java file with the 1.3.1_08 version. This got rid of the error "can't find java 2 runtime environment". I still have "can't find libjava.so" error. I've looked online and have found no comprehensive solutions.
I think the following solutions would be most helpful to me.
1) Help me fix this problem and end witth the 1.4.1 package or
2) Tell me how I can just get it back to how it was when I installed red hat 9 and I can start over trying to install 1.4.1 cleanly.
