Mysql communication failure during hand shake

Communication failure during hand shake: is mysql server running on
localhost 3306 port.

This is the most common error which mysql users encounter.

The following is the solution for the mentioned versions below:

Mysql Ver: 4.1

Go to mysql prompt.
run the command:
set password for (user-name)@(server-name) = old_password(“ur-password”);

Fill in the brackets with ur details and there u go!!!

Another common problem, is unable to find the mysql driver.
Just put the driver in tomcat/shared/classes
or tomcat/common/classes
