java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

Im building Maven Java Web application and when I do

Class.forName("com.mysql.jdbc.Driver");

I get

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver 

mysql-connector is added to my pom.xml file like this

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.32</version>
    <scope>provided</scope>
</dependency>

But I keep getting this. I even tried downloading mysql-connector and adding it manually to project, but it doesn't change anything.

I also have the same app without Maven, and same code works fine

You have set the scope of your dependency as provided. This means that the jar is used when compiling the project (although you shouldn't need it to compile it, since you should only use standard JDBC classes), but that it's not included in the jar or war created by the build, because this dependency is supposed to be "provided" by the application server where you deploy the application.

So, either you actually intend to have this jar provided, and it should be in the application server's classpath, or you want to bundle this jar with the application, and it should have the scope runtime (because you need it to run the app, but not to compile it), instead of provided.
