This document discusses using message properties in Mule applications. It provides an example Mule configuration file that demonstrates setting message properties in different scopes and logging their values. The example shows setting a property in the session scope and outbound scope in one flow, and accessing the same properties from the inbound scope in a second flow to illustrate how message properties work.

6. • Flow of execution:
1. URL to trigger the service from browser
http://localhost:8089/messageproperties
2. In flow1 both outbound and session property
is created using message property component
3. Service displays both outbound and session
properties in flow1
4. In flow2 the outbound property is changes to
inbound proeprty
5. Flow2 displays both inbound and session
property
