message queues necessary for routing

[lyfe]

This is somewhat related to a question I posted earlier (http://fusesource.com/forums/thread.jspa?threadID=1397).

I'm trying to create a few scenarios using web services.  A couple of these scenarios are:

- scatter gather pattern

- receiving input from a web service determines the next step

All the examples I've seen that closely relate to the scenarios I'm trying to do involve either message queues and/or using direct and seda.

Do I "need" to implement a message queue to accurately and efficiently implement my scenarios?

No message queues are not mandatory. You can do what you want.

A message queue however supports persistence and thus allows more fault tolerant solutions.

Unfortunately there is not a single solution. You gotta find out what suit you needs.
