h2. Definition of our integration process

Today you will bufferize messages, to process them all in one by _MathOperations_.


You will use Enterprise Integration Patterns (EIP, see below for explanations) to create this process :
* Several messages are sent to an *EIPAggregator* pattern, which bufferize all incoming messages.
* Trigger message is sent to *EipAggregator.*
* *EipAggregator* sends an aggregated message to *EipSPlitter*.
* *EipSplitter* splits the aggregated message back into multiple messages.
* *EipSPlitter* sends the multiple messages to the operation *AddIntegers* on the service *MathOperations.*
* *MathOperations.AddIntegers* processes the messages and send you the responses.

h2. Little bit of theory: EIP (Enterprise Integration Patterns) and XPath

*What is EIP ?*
A set of design patterns for enterprise application integration.
What is Agregator pattern ?

What is Splitter Pattern ?

Configure EIP Splitter pattern (10min)

h2. Configure the Aggregator

Configure EIP Aggregator pattern (10min)

h2. Test the EIP chain

Assemble the 2 SU in one SA and deploy (5min)
Test the Chain Aggregator=>Splitter=>MathOperations (15min)

h2. More about orchestration
