Summary 0003071: EJB 3.0 may not have public constructor
Description [22:06:22.246] {http--8443-9} Caused by: com.caucho.config.ConfigException: 'org.dicr.isp.ejb.PaymentDO' needs a public or protected no-arg constructor. Entity beans must have a public or protected no-arg constructor.

Steps To Reproduce
Additional Information @Entity
public class PaymentDO implements Serializable {
    protected PaymentDO() {
        super();
    }
}

There will no error, if I will change constructor to 'public'.
But error says 'public or protected no-arg constructor'.

2.1 Requirements on the Entity Class

"The entity class must have a no-arg constructor. The entity class may have other constructors as well. The no-arg constructor must be public or protected."

But Resin accept only public constructor. In my application public constructor is not acceptable, because I want to force use of my beans by user with right constructor with arguments. For example, I need to allow user to use:

@Entity
public class LoginDO {
    @Basic private String _name;

    protected LoginDO() {
        super();
    }

    public LoginDO(String name) {
        this.setName(name);
    }

    public void setName(String name) {
        if (name == null || name.length() < 1) throw new IllegalArgumentException("incorrect name");
        this._name = name;
}

I need to hide non-arg constructpr from user with 'protected' access.
But resin force me to make non-arg constructor public :(
