Vishal, did you look at the link that Fred provided?
The Cattle Drive has four sections:
* an introductory level
* classes and objects
* servlets
*
JDBC
The intent of the Cattle Drive is not to make you an expert programmer; it is to make you a better programmer.
One of the most important things that the Cattle Drive did for me was to help make me a programmer that other programmers are more likely to enjoy working with.
