在 JBoss AS 7 之前的版本中使用 SAR 時，你需要一個 extends 了 org.jboss.system.ServiceMBeanSupport 并 implements org.jboss.system.ServiceMBean 的類。但在 JBoss AS 7 中，這兩者都不存在了。

在 JBoss AS 7 中實現一個 MBean 你只需要一個實現了自定義接口的類。jboss-service.xml 中的配置和過去相同，但是必須制定 XML Schema，否則會有如下的異常：

<!-- lang: shell --> 23:10:52,007 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.deployment.unit."ServerMonitorService.sar".PARSE: org.jboss.msc.service.StartException in service jboss.deployment.unit."ServerMonitorService.sar".PARSE: Failed to process phase PARSE of deployment "ServerMonitorService.sar" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:121) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1765) at org.jboss.msc.service.ServiceControllerImpl$ClearTCCLTask.run(ServiceControllerImpl.java:2291) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [:1.6.0_21] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [:1.6.0_21] at java.lang.Thread.run(Thread.java:619) [:1.6.0_21]

JBoss AS 7 中 jboss-service.xml 配置示例：

<!-- lang: xml --> <?xml version="1.0" encoding="UTF-8"?> <server xmlns="urn:jboss:service:7.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="urn:jboss:service:7.0 jboss-service_7_0.xsd"><mbean code="custom.mbean.MyServerMonitor" name="service.server.monitor:service=MyMonitor"><attribute name="Frequency">5000</attribute></mbean> </server>
