I’m trying to make my program read/write in a database. I found this sample code to connect which compiles without problems:

“http://webhelp.ucs.ed.ac.uk/services/mysql/example2-java.php”

but Im having issues running it. Whenever I execute I get 

Failed to load mysql driver
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Do I need to download the driver manually and supply it through classpath or is it already given in java?

EDIT Alright, so I downloaded the driver but how can I run it with classpath to use the driver? I got this as my batch command but it gives me an error:

java -classpath driver/mysql.jar MySQL

and the error is

Error: Could not find or load main class MySQL

While without the classpath it finds the MySQL class :S

EDIT FIGURED IT OUT 😀

java -cp .;./driver/mysql.jar MySQL

    You need to download it. I would add it to a lib/ directory (in your project) and add that directory to your classpath.
