[Tomcat-jg-development] State transfer to new node

[Bela B. <be...@ya...>]

Filip, Bruce,

I noticed that transfer of all session to a new node is done by 2 
asynchronous EVT_GET_ALL_SESSIONS messages.
The new node sends this message to the current coordinator (first node 
started), which then sends back a unicast message for each session (and 
associated principal) to the joining node.

So if you have 100 sessions, the joining node will receive at least 100 
messages (EVT_SESSION_CREATED msg).

I'd like to change this to use the STATE_TRANSFER protocol of 
JavaGroups. To do so, I'll need your help:

    * Filip: is there a method to get all sessions as a byte buffer ?
      I'll also need a method to recreate and set the sessions given a
      byte buffer.
    * The default protocol stack needs to contain the STATE_TRANSFER
      protocol on top. Do we have default properties anywhere ? At least
      we need to change the documentation.

Cheers,
