------------------------------------------------------

please see the zip file.

in directory “dynamicloadjar” there're two classes,TestSimpleJdbc.java runs 
none exception,but TestDbutils.java runs error,it says:No suitable driver found 
for jdbc:mysql://127.0.0.1:3306/test

also when you run zhe program,please put the mysql_connector_5.1.15_bin.jar in 
D: directory

and modify mysql.properties with your mysql info

thank you!
