instalar o java

Pessoal
Nao to acertando isso do java.
Ele esta instalado, fiz uns links simolicos->
ln -s /usr/local/java/bin/java /usr/bin/java
 ln -s /usr/local/java/bin/javaws /usr/bin/javaws
 ln -s /usr/local/java/bin/java_vm /usr/bin/java_vm

Mas na hora que vou rodar o limewire(por exemoplo) o erro é:

Starting LimeWire...
Java exec not found in PATH, starting auto-search...
OOPS, unable to locate java exec in  /usr/lib/  hierarchy
You need to upgrade to JRE 1.4.x or newer from http://www.java.com
ls: /usr/java/j*: No such file or directory

ls: /opt/j*: No such file or directory
