all of mbeaninfo should not be always stored. for instance, if I instantiate my MMB by using a definition from an URL or db then the mbeaninfo is already persisted there and should not be duplicated (only the ref to where to locate it is needed). This is to avoid the confusion to users where an mbean seems to be stored in two different locations (we already had this problem with 2.0). If on the other hand you created the mbean info at runtime then obviously you need to persist it. The only changing part in the metadata should be the descriptor which should be persisted regardless of how the mbeaninfo was loaded to the runtime system in the first place. So a simple key, value map or a property file even. The rest of the metadata should remain unchanged during the lifetime of the MBean. > Could you clarify the following from P. 87 of the spec? how an mbean is persisted is really not defined in the spec. > If "the MBean" is (MB info + state), then this clearly states that the > *entire* MB is written.

I aggree that this does not make sense if the assumption doesn't make sense, and we both agree it doesn't make sense, then concentrate on the part that *does* make sense ;-) > Well, I'm very interested.
