h2. Create and deploy an EIP Service Assembly
There is a tight-coupling between both EIP. Assembling them in one single SA can be a good idea (especially with EIP, which can chain lots of patterns, each requiring a different SU).
# Create a new Service Assembly.
## *Name*: sa-Eip-AggregatorSplitter
# Add the two EIP Service-Units you created, and confirm
# Fast-export the Service Assembly for Petals.
# Deploy in Petals ESB.
h2. Review the chain
*EIP Agregator*
{code:lang=xml}<eip:aggregator-correlation>boolean(/*[local-name()="AddIntegers"])</eip:aggregator-correlation>{code}
Messages which satisfy "aggregator-correlation" will be aggregated. <=> Elements inside <AddIntegers> will be aggregated.
{code:lang=xml}<eip:test>boolean(/*[local-name()="AddIntegers"]/*[local-name()="equals"])</eip:test>{code}
Messages which satisfy "test" act as the, to send the aggregated buffer. <=> If <AddIntegers> contains <equals> element, aggregated message is sent to the next service and buffer cleared.
*EIP Splitter*
{code:lang=xml}<eip:test>//*[local-name()="AddIntegers"]</eip:test>{code}
Elements which satisfy "test" are extracted and sent to the next service. <=> <AddIntegers> elements are split and each one is sent in one message.
h2. Test the EIP chain
Deploy the SA containing the SU su-jsr181-MathOperations-provide. Deploy the SA sa-Eip-AggregatorSplitter.
Then we can send test messages from the webconsole. For example, we will send three messages, with InOut MEP (message exchange pattern), and then send the trigger message.
{code:lang=xml|title=Message 1|theme=Default}
<AddIntegers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<integer1>1</integer1>
<integer2>2</integer2>
</AddIntegers>
{code}
When everything is fine, you get this response, just saying the message was buffered :
{code:lang=xml|title=Response message|theme=Default}
<result xmlns="http://petals.ow2.org/petals-se-eip/aggregator">Aggregator: the content is buffered by the pattern</result>
{code}
We can continue to bufferize messages...
{code:lange=xml|title=Message 2|theme=Default}
<AddIntegers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<integer1>3</integer1>
<integer2>4</integer2>
</AddIntegers>
{code}
{code:lang=xml|title=Message 3|theme=Default}
<AddIntegers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<integer1>5</integer1>
<integer2>6</integer2>
</AddIntegers>
{code}
Let us send the trigger message :
{code:lang=xml|title=Message 4 - Trigger|theme=Default}
<AddIntegers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<equals/>
</AddIntegers>
{code}
Now all messages are processed by MathOperations :
{code:lang=xml|title=Response message|theme=Default}
<result xmlns="http://petals.ow2.org/petals-se-eip/splitter">
<dlwmin:AddIntegersResponse xmlns:dlwmin="http://test.petalslink.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<returnMessage xmlns="">3</returnMessage>
</dlwmin:AddIntegersResponse>
<dlwmin:AddIntegersResponse xmlns:dlwmin="http://test.petalslink.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<returnMessage xmlns="">7</returnMessage>
</dlwmin:AddIntegersResponse>
<dlwmin:AddIntegersResponse xmlns:dlwmin="http://test.petalslink.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<returnMessage xmlns="">11</returnMessage>
</dlwmin:AddIntegersResponse>
</result>
{code}
h2. More about orchestration
*Look at other EIP patterns. Simple theory exercise: how would you do in this case....?*
