Sri,
Welcome to JavaRanch! In the future, please ask each questtion in a separate thread. This will help you get a better faster answer.

I'm going to give you a link to the forum here at JavaRanch to ask follow up questions on each of these.

Testing forum - Unit testing is testing each class on its own without external resources like the database.

JDBC forum - Yes, it is possible to use JDBC in a servlet. JDBC is just Java code. There is nothing special about a servlet that would prevent you. See the JDBC tutorial.

OO forum - A data access object is used to hold you database code like JDBC.

IDEs and other tools forum - VSS (Visual Source Safe) is a source control system. CSS (cascading style sheets) is a technology for web pages, not a tool. You might have meant CVS (concurrent versioning system) which is also a source control system.
