I already have mysql  driver on my machine. My computer has win2000. I
put classpath c:\jdbc\mysql-connector-java-2.0.14-bin-jar

When I run small program to test it. I get some errors

SQLException: No suitable driver
Unable to load driver.
java.lang.NullPointerException
at DBTest.drop(DBTest.java:100)
at DBTest.main(DBTest.java:115)
Exception in thread "main" 

I could not figure it out. I don't think mysql use username and
password. Someone already download java  and mysql on my computer before
I got this computer. I was wonder if they set the username and password
as same as my computer username and passsword. How can we find  out?
