I have the same problem
but I found this after a long search:
http://www.herongyang.com/JDBC/MySQL-JDBC-Driver-Load-Class.html
But I made some change. I put the driver in the same folder as my ConTest.java file,
and compile it, resulting in ConTest.class.
So in this folder have
ConTest.class
mysql-connector-java-5.1.14-bin.jar
and I write this
java -cp .;mysql-connector-java-5.1.14-bin.jar ConTest
This way if you not use any IDE just cmd in windows or shell in linux.
