Answer 1

What is <classname>? Is that the "ClassToRun" from my example?
If so, add the path to the "root" of the package hierarchy where your class can be found.
For example:
Your class is in C:\Bogus\Bogus1\com\mine\MyClass.class
And its package is com.mine
Then your command looks like this:
java -cp "C:\full\path\to\jarfile\mysql-connector-java-5.0.5-bin.jar;C:\Bogus\Bogus1" com.mine.MyClass
Or your class is in C:\Bogus\Bogus1\myjarfile.jar
Then your command looks like this:
java -cp "C:\full\path\to\jarfile\mysql-connector-java-5.0.5-bin.jar;C:\Bogus\Bogus1\myjarfile.jar" com.mine.MyClassEdit. Added jar info
