Tells about Java in mule part 3

2. Reflection Entry Point Resolver:
 Reflection Entry Point Resolver is used to determine the entry
point of the component.
 Class method invocation happens based on the payload type as the
argument using reflection.
 For multiple parameters, the payload should be an Array of
objects.
 If the payload is other than Array type then the respective method
which has same type of argument will be invoked.
 If the message payload is of type Null Payload the resolver will
look for a no-argument method.

3.  Below sub flow uses java components to implement Reflection
Entry Point Resolver
 Below java class "EntryPointResolver" has three methods with
different argument types.
 multipleArgumentsMethod
 singleArgumentMethod
 noArgumentsMethod(){

5.  Multiple Arguments method:
Drag an expression component and write code to create Array
(strArray) of two String objects. Store that Array object into payload.

6.  Drag a java component and refer to a class "EntryPointResolver".

7.  As the payload is Array of two objects after 'Expression'
component, "multipleArgumentsMethod(String name, String
dept)" method of "EntryPointResolver" Class gets invoked.
Single Argument method:
 Drag a 'Set Payload' component and set value a string value as
"RAM". Drag a java component and refer to a class
"EntryPointResolver" as shown earlier.
 As payload is String type after 'Set payload' component,
"singleArgumentMethod(String name)" method of
"EntryPointResolver" Class gets invoked.
