It seems the mysql connectivity library is not included in the project. Solve the problem following one of the proposed solutions:
Add the mysql-connector dependency to the pom.xml project file:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.39</version>
</dependency>
Here you are all the versions: https://mvnrepository.com/artifact/mysql/mysql-connector-java
Add the jar library manually to the project.
Right Click the project -- > build path -- > configure build path
In Libraries Tab
press Add External Jar
and Select
your jar.
You can find zip for mysql-connector here
When building the project, java throws you an exception because a file (the com.mysql.jdbc.Driver class) from the mysql connectivity library is not found. The solution is adding the library to the project, and java will find the com.mysql.jdbc.Driver
