My java file modified from the github example:

	TransactionManager tm = com.arjuna.ats.jta.TransactionManager.transactionManager();
		EntityManagerFactory emf = Persistence.createEntityManagerFactory( "ogm-jpa-tutorial" );
		try {
			tm.begin();
			EntityManager em = emf.createEntityManager();
			User user = new User();
			user.setName( "User" );
			em.persist( user );
			String userId = user.getId();
			em.flush();
			em.close();
			tm.commit();

			tm.begin();
			em = emf.createEntityManager();
			user = em.find( User.class, userId );
			System.out.println("Found User :"+ user.getName());
			em.flush();
			em.close();
			tm.commit();

			emf.close();

Entity User :

@Entity
public class User {

	private String id;
	private String name;

	@Id @GeneratedValue(generator = "uuid")
	@GenericGenerator(name = "uuid", strategy = "uuid2")
	public String getId() { return id; }
	public void setId(String id) { this.id = id; }

	public String getName() { return name; }
	public void setName(String name) { this.name = name;} 
}

The code above is just the modified code for the Github Example Repo and it still doesn’t work.

The error states :

Caused by: java.lang.ClassNotFoundException: com.arjuna.common.util.propertyservice.PropertyManagerFactory
	at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:606)
	at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:168)
	at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522)
	... 5 more

I have tried with two or three dependencies for the PropertyManagerFactory already. What am I supposed to do now?

Please help.
