This section explains, through an example scenario, how the Message Dispatcher EIP can be implemented using WSO2 ESB. The following topics are covered:

Simulating the sample scenario
...
Repeatedly send several requests to the ESB using the stockquote client as follows:
ant
...
stockquote
...
-Dtrpurl=http://localhost:8280/
...
-Dsymbol=Foo
Given below is the request sent by the stockquote client in this example.
...
Let's investigate the elements of the ESB configuration in detail. The line numbers below refer to the ESB configuration in step 3 above.
- endpoint [line 14 in ESB config] - The endpoint element defines the endpoint to which a request should be sent to.
- loadbalance [line 15 in ESB config] - The loadbalance configuration defines a set of endpoints to which incoming requests are distributed to using a particular algorithm. In this example, the algorithm distributes messages in a weighted round robin manner.
