我正在第一次尝试Hyperic。 我有一个基本的服务器和代理安装程序，并在Redhat Linux机器上工作。 但是，当autodiscoverer运行JBoss 4.2的时候，我得到了这个消息结尾处的exception。
我在agent.propertiesconfiguration了jboss.installpath设置。 当我用DEBUG级别的日志logging启动代理时，我看到了从我configuration的path中包含的各种JBoss jar包。 但是我不能自动发现JBoss，我仍然得到相同的例外。 任何想法如何解决这个将不胜感激…

将JBoss中的jbossall-client.jar放置在Hyperic Agent的类path中（即在Hyperice Agent的相关库中）。
另外检查..
这个问题可能是由于Hyperic Agent不能捕获JBoss-Server，因为使用了反斜杠而不是普通的斜线。
jboss.installpath = e：\ jboss-4.2.1.GA – >不行
jboss.installpath = e：/jboss-4.2.1.GA->确定
