I am writing a simple Servlet that uses JDBC to talk to MySQL and deploying it
in Tomcat. Why do I need to add the line -:
Class.forName(com.mysql.jdbc.Driver);
to load the JDBC driver ? If I don’t do this I get an exception of -:
java.sql.SQLException: No suitable driver was found.
Why is
What is the SYSTEM PATH that you are referring to ? Is it the JAVA_HOME or the
PATH system variable ?
What is the CLASSPATH just before Tomcat properly starts up ? What is it after
it starts up ? Is the same jar files below -:

javax.servlet.HTTPServlet class has a non abstract implementation of the doGet,
doPost, etc methods. Why not just declare them abstract ? I mean HTTPServlet is
an abstract class so why take the trouble to write
So why is there users-h...@tomcat.apache.org ? Is it redundant ? And also how
