Hi,
I am a new user of Fedora. I should work with an open source package which works in Linux. Therefore, I installed Fedora 11. At the moment, I must install Apache Ant to continue. However, I am confused! I don’t know how. I appreciate if you tell me the details you know about installing it.

The other question is: What is the different between JDK, SE and J2SDK in Linux. The package said that I should set JAVA_HOME =/usr/java/j2sdk1.4.2_04; however, I did not find that on my system. Is it possible to set it to (for example) /etc/java OR /etc/alternatives/…?
Thanks
