Hello everybody.

On Linux CentOS 7.1.1503, I have Firefox 31.4.0 and Java 1.7 installed by default. I need to have Java 1.6 used by Firefox.

I installed Java 1.6 rpm. As suggested here : - https://wiki.centos.org/HowTos/JavaRuntimeEnvironment (chapter Java x86_64 JRE and plugin) In - /usr/lib64/mozilla/plugins/ I created a symlink that points to - /usr/java/latest/lib/amd64/libnpjp2.so (located in JRE 1.6).

When I display "about:addons", Java 1.6 is listed, BUT, when a load a simple HTML page (see code below) aimed to display Java version _really_ used, 1.7 is displayed.

Thanks for advance for your help. Frederic.

--- HTML code ---


<title> A Simple Program </title> Java Version : <APPLET CODE="JavaVersion.class" WIDTH=250 HEIGHT=75> </APPLET>


--- JavaVersion.java ---

import java.applet.Applet; import java.awt.Graphics; public class JavaVersion extends Applet { 

   public void paint(Graphics g) {
       String version = System.getProperty("java.version");
       g.drawString(version, 10, 10);
   }

}

I found the solution. I (also) had IcedTeadPlugin, which actually points to JRE 1.7. So, it was loaded instead of JRE 1.6.
