Universal Message Object (UMO) • A UMO is a type of Java object that can – receive events "from anywhere" – send events • UMO Components are usually your business objects. They are components that execute business logic on an incoming event • UMO are standard JavaBeans (containers) • There is no Mule-specific code in your components • Mule handles all routing and transformation of events to and from your objects based on the configuration of your component

  • 13. © SpringPeople Software Private Limited, All Rights Reserved. Exception Handling • Mule has a special way of handling non-happy path processing. This is called an "Exception Strategy" but is it really just and exception path and there is very little strategy involved. • There are three places you can associate an exception strategy – connector – component – model (set for all components in a model)
  • 14. © SpringPeople Software Private Limited, All Rights Reserved. Exception Strategy • We want all invalid documents to be moved into the error folder. <exception-strategy className=org.mule.impl.DefaultComponentExceptionStrategy"> <endpoint address="file:///c:/mule-class/error"/> </exception-strategy>
