Hello all,

Im unsure of which java jdk version my machine is using due to the following output:

[root@capote init.d]# java -version
java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Server VM (build 1.5.0_05-b05, mixed mode)
[root@capote init.d]#
[root@capote init.d]#
[root@capote init.d]#
[root@capote init.d]#
[root@capote init.d]# echo $JAVA_HOME
/usr/java/jdk1.6.0_21

Can someone please tell me why there are 2 different versions displayed here?

Thanks

Simply put: it seems that you have multiple versions of Java installed.  

A very nice overview of JRE on Linux can be found here: http://ice.he.net/~hedden/jrelinux.html (at least I found it useful!)

find / -type f -name java

will show you all of them installed.

"which java" - one that you run by a simple command
