rmi调试

1.服务端报错信息如下：
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
         java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
         java.lang.ClassNotFoundException: ISegment
解决办法： 
控制台执行如下：
set classpath=%classpath%;D:\wordSerach\tdp-common-lib\lib\SegmentCt-0.0.1-SNAPSHOT.jar
start  rmiregistry
2、客户端报错如下：
caused by java.rmi.NotBoundException:
原因是 服务端没有正确设置 rmiUrl
正确的设置应该是：
// srvRmiUrl = "rmi://localhost:1099/Segment";
srvRmiUrl = "Segment";
ISegment stub = (ISegment) UnicastRemoteObject.exportObject(impl, 0);
registry.rebind(srvRmiUrl, stub);

3、web工程引入 SegmentCt-0.0.1-SNAPSHOT.jar，没有将此jar放置于web工程的lib目录下面，而是直接引用
在xml文件注入类：





 

报错信息 提示找不到类  com.tellhow.searchplatform.segmentct.SegmentProxy
解决办法：
在build path中删除 外部依赖包SegmentCt-0.0.1-SNAPSHOT.jar，把 SegmentCt-0.0.1-SNAPSHOT.jar复制到 WEB-INF的lib目录下面，

加载到build path中。

    近段由于项目中要用到jmx，所以对其有所接触！从网上获得一些示例代码后就开始动手了，入门的代码网上很多，但是有些要留意的地方没有提及！这里就说下mbean的命名规范的问题。这个情况是我在把MBean注册到MBean服务器的时候遇到的。大致的情况是出现了下列异常信息：

Create an RMI connector server
javax.management.NotCompliantMBeanException: MBean class com.skywin.monitor.appadt.mbean.GlobalsdrMbeanImpl does not implement DynamicMBean, neither follows the Standard MBean conventions (javax.management.NotCompliantMBeanException: Class com.skywin.monitor.appadt.mbean.GlobalsdrMbeanImpl is not a JMX compliant Standard MBean) nor the MXBean conventions (javax.management.NotCompliantMBeanException: com.skywin.monitor.appadt.mbean.GlobalsdrMbeanImpl: Class com.skywin.monitor.appadt.mbean.GlobalsdrMbeanImpl is not a JMX compliant MXBean)

 查了资料才知道，是我的MBean不符合命名规范 ！命名规范要遵从一下两点

 

1标准MBean 名称必需是在要监控的类名后面加上“MBean ”,

 

2监控的类和MBean 接口必需在同一包下

也可以理解为注册的接口名字必须以MBean结尾，接口实现类比接口名字少了MBean,而且接口和接口实现类必须放在同一个包下
