Proper usage of ANT in F16?

[sepoto]

I started with a fresh installation of F16 and then used the package manager to first install AXIS and then install ANT. Upon changing to the /bin directory of my application and running as requested of me:

> ant deploy

I then receive this message from ant:

The JAVA2_HOME environment variable needs to be set in order to use this ant script.

I have never had to set this variable before. Does anyone know how to do this with ant?

The entire console output I will past below:

I think JAVA_HOME is in usr/lib/ I'm going with that.
