That's a not a good thing to do. You should not place external jars under JDK. You can have different location for those jars. For your question, as you topic suggest program is unable to find the class (may be the driver implementation). Try placing the jar in different location and set the CLASSPATH system variable pointing to that jar (in addition to what it currently pointing to) and run your code then see what happens, if that doesn't work provide more details about your code etc..

Do you know how to set the classpath system variable in windows? Or try setting it at the time you run JVM like :

java -classapth "Your path to the jar file & the class file/any other class files your program uses" NameOftheClassFile.

See what happens.

There's a nice FAQ entry about setting the classpath.
