You need to set PATH variable , something like

export PATH=$PATH:/usr/java/jdk1.5.0_07/bin

replace /usr/java/jdk1.5.0_07/bin with path to your jdk's bin directory.

The problem is your terminal tries to find java command from the PATH , but it couldn’t find it.

Update:

You need to setup global config in /etc/profile OR /etc/bash.bashrc file for all users:

# vi /etc/profile

Next setup PATH / JAVA_PATH variables as follows:

export PATH=$PATH:/usr/java/jdk1.5.0_07/bin
export PATH=$PATH:/usr/java/jdk1.5.0_07/bin
