java - weblogic ejb ComplianceException

Question

我尝试在 weblogic 10.3 上部署一个使用 EJB 的应用程序。我使用框架seam 2.2.0

我使用研讨会创建了一个 EJB 项目和一个 EAR 项目。

当我编译项目时，我得到这个错误:

weblogic.ejb.container.compliance.ComplianceException: No business interface, component interface or web service endpoint interface found for Session Bean Authenticator

下面是bean代码:

import javax.ejb.Local;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.contexts.SessionContext;
import org.jboss.seam.faces.FacesMessages;
import org.jboss.seam.faces.Redirect;
import org.jboss.seam.log.Log;
import org.jboss.seam.security.Credentials;
import org.jboss.seam.security.Identity;
import org.jboss.seam.security.crypto.BinTools;
import org.jboss.seam.security.management.IdentityManager;
import org.jboss.seam.security.management.JpaIdentityStore;

@Stateless
@Local
@Name("authenticator")
public class Authenticator {
}

这里是异常(exception):

我不明白我的错误。

感谢您的帮助。

发生这种情况是因为 Weblogic 正在寻找 Authenticator 实现的接口(interface)。

更改为:

@Stateless
@Name("authenticator")
public class Authenticator implements AuthenticatorLocal {

    @Override
    public void oneMethod()
    {
      //enter code here
    }
}

@Local
public interface AuthenticatorLocal {
    void oneMethod();
}

注意:接口(interface)必须至少有一个被覆盖的方法，否则你会再次得到同样的错误。
