Question

任何人都可以帮我解决问题吗？

我的com.intel.esg.ecp.cli.Command连接到JMX，并找到MXBean com.acme.AcmeManager，它假设调用createObject来创建AcmeObject。

AcmeManager和AcmeObject都设计为MXBean，我发布了没有问题。

堆栈是否意味着AcmeObject不确认MXBean标准或AcmeManager不确认MXBean标准？我是JMX MXBean的新手，有人可以给我一些有用的资料吗？

由于

MXBean概念提供了一种仅对MBean进行编码的简单方法引用一组预定义的类型，由...定义 javax.management.openmbean中。通过这种方式，你可以确定你的任何客户端（包括远程客户端）都可以使用MBean 客户端可以访问特定于模型的类的任何要求代表MBean的类型。

显然， com.acme.Acme 和 com.acme.AcmeObject 是自定义类型，并且它们不定义与opendata类型之间的转换。有关详细信息，请参阅OpenData type mapping rules。
