昨天同事在JBoss中部署MBean時一直報錯：

幾個人查了良久，試了能想到的一切方法，仍不得解。網上Google，Interface和實現必須放在同一個包內，改，再部署，仍報錯。同事提了一句是不是要改成Sar包，改，再部署，仍舊報錯。MBean命名有要求，實現類名必須是接口名去掉MBean，改，再部署，還是錯措錯！！！最後大家都已頭昏眼花，不得不暫時作罷，次日再戰。
今日一早起來，略讀了《Java Management Extension》，書中 2.2.1節 Describing the Management Interface 正好講到了NotCompliantMBeanException。遂一一對照，檢查代碼。
2.2.1.1 Pattern #1: Defining, naming, and implementing the MBean interface
接口必須定義成Public的。
public interface QueueMBean {
// management interface goes here. . .
}
實現類必須implements 接口的同時，名字也是大有講究。假如接口名叫 XYZMBean ，那麼實現名就必須一定是XYZ，而且是大小寫敏感的。真是差之毫釐謬以NotCompliant。
public class Queue implements QueueMBean {
// implementation of QueueMBean
// and other stuff here. . .
}
再仔細一瞅同事的代碼，頓悟。接口名去掉MBean後和實現類名差那麼一個字母，怎麼昨天我們三個人都沒有看出來呢？把名字一改，再部署，OK了。
