If you get this error when you are running it, then probably its because you have not included mysql-connector JAR file to your webserver's lib folder.

Now it is important to add mysql-connector-java-5.1.25-bin.jar to your classpath and also to your webserver's lib directory. Tomcat lib path is given as an example Tomcat 6.0\lib

problem is not in the code   but you don t have added the driver to your project    You have to add the   jar driver to your project        Try putting this in your lib directory  then re-starting tomcat     problem is Class forName  com mysql jdbc Driver     it tries to load the driver  but it is not getting it  this is the reason you are getting      java lang ClassNotFoundException
