I have downloaded and installed the mysql driver.
The class path is all right.
It compiles with success but when it runs, it doesn't recognise the following driver
the message is java.lang.ClassNotFoundException:
Does anybody know where is the error?

It's a classpath error most likely.
Your compile environment has one classpath that includes the MySQL driver. Your servlet environment does not have the same classpath.
If your servlet environment is 2.2 or higher (or if you are using a .war file), just drop the jar file for the database into your WEB-INF/lib directory and see if that helps.
Another hint: Lots of newbies forget to call DriverManager.registerDriver. You need to do that if you are not using a DataSource
Don't get me started about those stupid light bulbs.
