Agenda

3

The nature and benefits of

open source

Open technologies for

integration

Features in IBM Integration Bus to support and

encourage open source

Nature of open source software • Open source definition

• 10 point list of guidelines

4

Nature of open source software • Open source definition

1. Free Redistribution 2. Source Code 3. Derived Works 4. Integrity of The Author's Source Code 5. No Discrimination Against Persons or Groups 6. No Discrimination Against Fields of Endeavor 7. Distribution of License 8. License Must Not Be Specific to a Product 9. License Must Not Restrict Other Software 10. License Must Be Technology-Neutral

5

Nature of open source software

Free Software definition

6

Free software” means software

that respects users' freedom and community.



7



the users have the freedom to run, copy, distribute,

study, change and improve the

software



8



the users have the freedom to run, copy, distribute,

study, change and improve the

software

think of “free” as in “free speech,”

not as in “free beer”

9

Community and Collaboration

10

License and copyright

11

Branching, Forking and Cloning

Benefits of open source

12

Early access to new product capabilities

Expert collaboration from a diverse community

Extend product capabilities to suit your specific need

Discovery Exchange

Connector API

Java .NET .js … C Exposed via the integration platform’s programming model.

Exposed via the integration platform’s administration interfaces.

Policy

Services and events are everywhere! – Allow different systems to have their input and outputs defined as services, events & documents

• e.g. database, MQ, SAP, CICS, mobile, machine devices, sockets… Integrating endpoint systems involves three key processes

– Discovery: Understand & capture the end system inputs and outputs – Exchange: Send data to and from these systems, using event, service, document metaphor – Policy: Control behaviour dynamically

Connector Framework – Simplifies application connector development and restructures UDN development to be endpoint-

centric rather than IIB-centric

IIB Connector API • Natural and Obvious

• Facilitates re-use of existing connectors and clients. • Clean abstractions and separation of concerns

• API does not require understanding of IIB concepts • Allows for standalone unit testing and component testing

• Patterns of interactions • To fit in well with existing client libraries • Support consistent behaviour and end user experience

Is there an existing

connector?


28

public static void main(String[] args) { NonBlockingClient client = NonBlockingClient.create("amqp://localhost", null, null); client.subscribe("/public", new DestinationAdapter() { public void onMessage(NonBlockingClient client, Void context, Delivery delivery) { switch (delivery.getType()) { case BYTES: BytesDelivery bd = (BytesDelivery)delivery; System.out.println(bd.getData()); break; case STRING: StringDelivery sd = (StringDelivery)delivery; System.out.println(sd.getData()); break; } } }, null, null); }


Find some sample code.

Start with hello world


29

public class AMQPConnectorFactory extends AbstractConnectorFactory { @Override public InputConnector createInputConnector(String name) throws ConnectorException { return null; } @Override public String getInfo() { return "AMQP Client Connector"; } @Override public OutputConnector createOutputConnector(String name) throws ConnectorException { return null; } @Override public RequestConnector createRequestConnector(String name) throws ConnectorException { return null; } }

Implement a connector

factory



30

public InputConnector createInputConnector(String name) throws ConnectorException { return new AbstractInputConnector(){ @Override public void start() throws ConnectorException { } @Override public void stop() throws ConnectorException { } @Override public boolean isStarted() { return true; } }; }

Create at least one type of

connector



31

@Override public InputConnector createInputConnector(String name) throws ConnectorException { return new AbstractInputConnector(){ @Override public void start() throws ConnectorException { getCallback().processInboundData( new String("hello world").getBytes(), null); } @Override public void stop() throws ConnectorException { }

Hard code a fake

32

Create some mock classes

33

public class AMQPConnectorFactoryTest { AMQPConnectorFactory fixture; @Before public void setUp() throws Exception { fixture = new AMQPConnectorFactory(); } @Test public void testGetInfo() { String info = fixture.getInfo(); assert(info.equals("AMQP Client Connector")); } @Test public void testCreateInputConnector() throws ConnectorException { InputConnector inputConnector = fixture.createInputConnector("TestConector"); assertNotNull("createInputConnector returned null", inputConnector ); } }
