我尝试在WebLogic10.3上部署一个使用EJB的应用程序。我使用框架seam 2.2.0

我创建了一个EJB项目，并在研讨会上创建了一个新项目。

当我编译这个项目时，我得到了这个错误：

代码语言：javascript
运行
复制
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：

代码语言：javascript
运行
复制
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 {
}

下面是一个例外：

这是因为Weblogic正在寻找Authenticator实现的接口。

更改为：

代码语言：javascript
运行
复制
@Stateless
@Name("authenticator")
public class Authenticator implements AuthenticatorLocal {

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

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

注意:接口必须至少有一个被重写的方法，否则您将再次得到相同的错误。

这是因为weblogic将搜索EJB本地服务的接口：

代码语言：javascript
运行
复制
@Stateless
@Local
@Name("authenticator")
public class Authenticator {
}

如果你实现一个接口，并把它提供给EJB，这个问题就解决了。如下所示：

代码语言：javascript
运行
复制
@Stateless
@Local(IAuthenticator.class)
@Name("authenticator")
public class Authenticator implements IAuthenticator{
 //your business logic
}

public interface IAuthenticator {
   // interface
}
