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.

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'.

Notes
(0003550) dicr 11-17-08 19:41	ejb-3_0-fr-spec-persistence.pdf 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 :(
