Hi All,

I am using SunOS 5.8 and KSH shell. My problem is , I can't find my java installed directory. Java is running from /usr/bin folder but I think there java is the link to actual java directory. Also nothin is set to $JAVA_HOME env variable. How to see the actual program location pointed by 'usr/bin/java' link.

Please help me as I am struggling to find it out for past 3 hours.

~/$ ls -l /usr/bin/java
lrwxrwxrwx 1 root other 16 Jul 27 2007 /usr/bin/java -> ../java/bin/java

so /usr/java/bin/java is my JRE unless there is a link further up that chain...

ls -l /usr/java
lrwxrwxrwx 1 root other 15 Jul 8 2009 /usr/java -> jdk/jdk1.5.0_19

so is /usr/jdk/jdk1.5.0_19 , well it would seem not...

ls -l /usr/jdk/jdk1.5.0_19
lrwxrwxrwx 1 root other 18 Jul 8 2009 /usr/jdk/jdk1.5.0_19 -> instances/jdk1.5.0

and finally

ls -l /usr/jdk/instances/jdk1.5.0
total 34630

So in my case //usr/jdk/instances/jdk1.5.0/bin/java is my actual binary
