Try to execute the program once again, it should work properly. Not able to connect to the MySQL server through executing the SQL script plugin.Navigate into the location of the mysql-connector-java-5.1.24-bin.jar JAR file.Right-Click on the eclipse project that uses the JPA.In case you are using a MySQL database, then you should add mysql-connector-java-5.1.24-bin.jar into your classpath. It will not be added by default, you have to add it by yourself. The main cause of this exception is because the driver of the database is missed from your eclipse project’s classpath.

The major important issue needs to take care of while development of a project using a JPA, is a database driver that can help the JPA communicates with the suggested database. The EclipseLink – JPA API is persistence service that provided a standard way to communicate with the database.
