This tutorial is based on [EIP Buffer complex use case].

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.
  

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

What is EIP ?

What is Agregator pattern ?

What is Splitter Pattern ?

What is XPath ?

Configure the Splitter

Configure EIP Splitter pattern (10min)

Configure the Aggregator

Configure EIP Aggregator pattern (10min)

Test the EIP chain

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

More about orchestration

Theory: Look at other EIP patterns. Simple theory exercise: how would you do in this case....? [TODO] (15min)
Theory: Other orchestration ways: BPEL, SCA, JSR181 or POJO. More info in whitepaper. (5min)
