Willem Jiang updated CAMEL-215:
-------------------------------

    Attachment: camel-215.patch

This patch just implement configure the load balance endpoints with a static list.
We could add the dynamical endpoints support  in the next phase.

> LoadBalancingProcessor myStrategy;  // my own strategy to choose an endpoint
>  from(endpointA).loadBalance().setLoadBalance(myStrategy).to(Endpoint1, Endpoint2, ...);
>  or if can use an out of the box strategy like:
>  from(endpointA).loadBalance().roundRobin(),to(endpoint1, endpoint2, ...);
> Just a minor twist on that idea; how about
> from(endpointA).loadBalance().roundRobin().endpoints().<someExpression>
> where loadBalance() returns a LoadBalanceClause rather like filter()
> returns an ExpressionClause which lets folks pick the strategy of load
> balancer to use.
> Using a named reference could be by
> from(endpointA).loadBalance().ref("someName")...
> I also added the idea of using an expression to determine the
> endpoints to load balance across as we might wanna support dynamic
> load balancing. e.g. querying the endpoints in OSGi or JNDI or
> whatever.
