We need a tool which will help in making application simpler and faster. The answer is ant…

To use ant you should have eclipse or you should get ant…

Before installing ant you should have JDK installed. JAVA_HOME should point to appropriate JDK.

Set ANT_HOME to binary distribution of ant.. depending upon your system(Windows,Unix)…

Example : ANT_HOME = D:\sameer\apps\ant

after setting… check in command prompt

ant -version press enter..

You will get this…
