Thank you for your helpful posts, Eric. It really helped me figure
some things out.
So here's what I'm going to do:
Create 2 beans:
- SyncToCrmBean
- SyncFromCrmBean
SyncToCrmBean:
- Registers a global mailbox listener, so it receives all the events
related to the modification of any message
- Opens a JMS channel (we're probably going to use ActiveMQ, since
that's already integrated with JAMES, too)
- It only handles events with the session type "user" (so we only
react to events actually done by the user)
- Whenever we get a notification, we create the appropriate JMS
messages and send them to the JMS channel, including the message ID of
the corresponding message (so we can find the correct messages in our
CRM)
SyncFromCrmBean:
- We start a JMS listener, listening for messages that we send to this
queue. They come from our CRM and contain status information about
messages
- We use the mailbox manager to create a system session
- Through this system session we access the correct mailbox (using
e-mail address, namespace and mailbox name)
- We find the messages using the Message-ID supplied from our CRM
- We do the appropriate actions on the messages
- JAMES triggers the message events, but they are triggered from a
system session, so we can ignore these in the SyncToCrmBean.
Then we have some programming to do in our CRM/database/ESB, but this
doesn't really regard JAMES. It basically takes care of sending and
receiving messages to and from the appropriate JMS channels to do
status updates in the database.
But as far as I can see, JAMES is ready to do everything we want for now. :)
PS: Is it possible to create a system session through a normal
IMAP-connection? It would be so much easier to just push the messages
to our IMAP-server using standard tools, rather than receiving
everything through JMS or something else and programmatically storing
everything etc.
