干净构建失败在NetBeans

创建在NetBeans IDE的项目6.9 在一个项目中，我有一个接口IBusinessLogic 在第二个项目中，我创建了一个类BusinessLogic它实现IBusinessLogic 在第三个项目我创建BusienssLogic的对象并将此对象分配给IBusinessLogic的引用。我没有得到任何错误而写，但是当我清理并生成第三项目中，我得到异常，下面：干净构建失败在NetBeans

 
incompatible types 
found : com.abc.businesslogic.BusinessLogic 
required: com.abc.businesslogic.interfaces.IBusinessLogic 
       com.abc.businesslogic.interfaces.IBusinessLogic logic = bl;

D:\ProjectsFeb12\Service\nbproject\build-impl.xml:531: The following error occurred while executing this line: 
D:\ProjectsFeb12\Service\nbproject\build-impl.xml:261: Compile failed; see the compiler error output for details. 
BUILD FAILED (total time: 3 seconds)

当我知道我可以指定在超类型的基准子类型的对象，那么这异常必须是IDE。我该如何解决这个问题？我把我的所有代码都移到了一个新项目中，但没有成功。

代码：

 
package com.abc.workerhandlers; 

import com.abc.businesslogic.BusinessLogic; 
import com.abc.businesslogic.interfaces.IBusinessLogic; 

public class MQ2MQWorker1 { 

    MQ2MQWorker1(){} 

    public void init(){ 

       BusinessLogic bl = new BusinessLogic(); 
       IBusinessLogic logic = bl; // This line is giving problem 
    } 
}

当我运行它完美地执行该项目，但该项目的罐子在dist目录中没有创建。

你可以发布一段代码的错误所在出现？ – 2012-03-27 06:21:51

您确定'com.abc.businesslogic.BusinessLogic'实现了'com.abc.businesslogic.interfaces.IBusinessLogic'吗？ – 2012-03-27 06:21:53

@JimGarrison我确定。 – sjain 2012-03-27 06:30:15

你确定类路径中有正确的类吗？顺便说一句，你不应该写

BusinessLogic bl = new BusinessLogic(); 
IBusinessLogic logic = bl; // This line is giving problem

而只是IBUsinessLogic logic = new BusinessLogic();
