[Openjmx-devel] New RMI Adaptors architecture

[Bordet, S. <Sim...@co...>]

Hi all,

so I have just finished the RMI adaptors, and found a better =
architecture to implement them.

Current one is:

RMIConnector --> network --> RMIProtocolAdaptor --> MBeanServer

where RMIAdaptor sits on top of the RMIProtocolAdaptor to give =
manageability to it.

New one will be:

RMIConnector --> network --> RMIProtocolAdaptor --> Interceptor 1 --> =
Interceptor 2 --> ... --> Interceptor n --> MBeanServer

Every interceptor is an MBean and it's registered along with the =
RMIAdaptor MBean.
It is possible to enable/disable the interceptors, and every interceptor =
can perform operations based on the informations it has.
For example one can write an interceptor that uses JAAS to allow or not =
certain users to perform some operations, or not use JAAS and do the =
same kind of checks.
Or another interceptor that will record different users, or one that =
records the hit per second of the interceptors, and so on.

I've already done 90% of the new architecture and seems to work well.

It will have much more dynamicity, manageability, and it is easily =
extendible by a user that wants custom interceptors.

I think I will replace the old architecture with this new one, keeping =
all the good features of the previous (IIOP, SSL, remote listeners, =
etc). The new architecture only affects the management part, and =
slightly the implementation. For example for users is transparent: the =
usage is the same I don't have even to change the documentation :)

Opinions are welcome
