Hello,

I have the following in /usr/java :

[root@jonas java]# ls -l
total 40668
lrwxrwxrwx. 1 root root 16 2010-11-26 15:45 default -> /usr/java/latest
drwxr-xr-x. 7 root root 4096 2010-11-26 15:44 jre1.6.0_22
-rw-r--r--. 1 root root 20946625 2010-09-15 12:42 jre-6u22-linux-i586.rpm
-rwxr-xr-x. 1 root root 20691198 2010-11-26 16:00 jre-6u22-linux-i586-rpm.bin
lrwxrwxrwx. 1 root root 21 2010-11-26 15:45 latest -> /usr/java/jre1.6.0_22

But the jre-6u22 is not listed :

[root@jonas java]# /usr/sbin/alternatives --config java

There are 3 programs which provide 'java'.

Selection Command
-----------------------------------------------
+ 1 /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
2 /usr/lib/jvm/jre-1.5.0-gcj/bin/java
* 3 /usr/java/default/bin/java

Enter to keep the current selection[+], or type selection number:


How can I run java jre-6u22 ??

Probably like this : (( LQ Search , Tag = alternatives ))

Setting up a new java : 1) su
2)
/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jre1.6.0_22/bin/java 22

3) /usr/sbin/alternatives --config java

..

I need to set a variable $JRE_HOME which points to the folder where Java is installed.

What directory is this then ?

The directory that contains the "bin" subdirectory.

/usr/java/jre1.6.0_22
