Question

I’ve been trying to fix this error:

{“exception”:”Persistent class \”Class org.myapp.model.Account does
not seem to have been enhanced. You may want to rerun the enhancer and
check for errors in the output.\” has no table in the database, but
the operation requires it. Please check the specification of the
MetaData for this class.”}

I’ve tried cleaning up the project

This is the Entity that I’m trying to persist:

@SuppressWarnings("serial")
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Account implements Serializable {
    @PrimaryKey
    @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
    private Long id;
    @Persistent
    private String username;
    @Persistent
    private String password;

    public Account() {

    }
    // Code omitted
}

How can I fix this issue?

Answer 1

Check two things

Do you have The Entity in “classes to be enhanced list” of eclipse appengine plugin.
Do you have multiple appengine sdk library versions in your classpath.
