java - Class [org.apache.derby.jdbc.ClientDriver] not found

Trying to connect to derby data base, and I get a below mentioned error:

Here is a main class:

public class App {

    public static void main(String[] args) {
        Customer customer = new Customer("Anthony", "Balla", "[email protected]");
        Address address = new Address("Rirherdon RD", "London", "8QE", "UK");
        customer.setAddress(address);

        EntityManagerFactory emf = Persistence.createEntityManagerFactory("chapter06PU");
        EntityManager em = emf.createEntityManager();
        EntityTransaction et = em.getTransaction();

        et.begin();
        em.persist(customer);
        et.commit();
        em.close();
        emf.close();

    }
}

Here is Persistence Unit:

<?xml version="1.0" encoding="UTF-8"?>

      <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
    </properties>
  </persistence-unit>
</persistence>

The data base running:

Fri Jan 17 10:37:31 CET 2014 : Security manager installed using the Basic server
 security policy.
Fri Jan 17 10:37:31 CET 2014 : Apache Derby Network Server - 10.10.1.1 - (145826
8) started and ready to accept connections on port 1527

and I believe I have the dependency to the client in POM:

<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derby</artifactId>
    <version>10.10.1.1</version>
    <type>jar</type>
</dependency>

Can you advice?

You need a derby driver installer in the application server for this to work. It is not enough to include it in your application itself.

The simplest way to do so for the Java distributions at the time the question was asked, as I believe Derby is included in the JDK, is to tell JBoss to use the JDK instead of the default JRE.

You need just to use derbyclient instead of derby as artifactId:

<dependency>
    <groupId>org.apache.derby</groupId>
    <artifactId>derbyclient</artifactId>
    <version>10.10.1.1</version>
    <type>jar</type> 
</dependency>

You must copy derbyclient.jar in your Tomcat server's lib folder.

See this answer.

Says the JDBC driver is not found. Have you included it in your library?
