Enterprise Integration Patterns
Camel supports most of the Enterprise Integration Patterns. If you are new to Camel you might want to try the Getting Started in the User Guide before attempting to implement these patterns.

Messaging Systems Image Modified | Message Channel | How does one application communicate with another using messaging? | Image Modified | Message | How can two applications connected by a message channel exchange a piece of information? | Image Modified | Pipes and Filters | How can we perform complex processing on a message while maintaining independence and flexibility? | Image Modified | Message Router | How can you decouple individual processing steps so that messages can be passed to different filters depending on a set of conditions? | Image Modified | Message Translator | How can systems using different data formats communicate with each other using messaging? | Image Modified | Message Endpoint | How does an application connect to a messaging channel to send and receive messages? |
Messaging Channels Image Modified | Point to Point Channel | How can the caller be sure that exactly one receiver will receive the document or perform the call? | Image Modified | Publish Subscribe Channel | How can the sender broadcast an event to all interested receivers? | Image Modified | Dead Letter Channel | What will the messaging system do with a message it cannot deliver? | Image Modified | Guaranteed Delivery | How can the sender make sure that a message will be delivered, even if the messaging system fails? | Image Modified | Message Bus | What is an architecture that enables separate applications to work together, but in a de-coupled fashion such that applications can be easily added or removed without affecting the others? |
Message Routing Image Modified | Content Based Router | How do we handle a situation where the implementation of a single logical function (e.g., inventory check) is spread across multiple physical systems? | Image Modified | Message Filter | How can a component avoid receiving uninteresting messages? | Image Modified | Recipient List | How do we route a message to a list of dynamically specified recipients? | Image Modified | Splitter | How can we process a message if it contains multiple elements, each of which may have to be processed in a different way? | Image Modified | Resequencer | How can we get a stream of related but out-of-sequence messages back into the correct order? |
Image Modified | Content Enricher | How do we communicate with another system if the message originator does not have all the required data items available? | Image Modified | Content Filter | How do you simplify dealing with a large message, when you are interested only in a few data items? | Image Modified | Normalizer | How do you process messages that are semantically equivalent, but arrive in a different format? |
Messaging Endpoints | Messaging Mapper | How do you move data between domain objects and the messaging infrastructure while keeping the two independent of each other? | Image Modified | Event Driven Consumer | How can an application automatically consume messages as they become available? | Image Modified | Polling Consumer | How can an application consume a message when the application is ready? | Image Modified | Competing Consumers | How can a messaging client process multiple messages concurrently? | Image Modified | Message Dispatcher | How can multiple consumers on a single channel coordinate their message processing? | Image Modified | Selective Consumer | How can a message consumer select which messages it wishes to receive? | Image Modified | Durable Subscriber | How can a subscriber avoid missing messages while it's not listening for them? | | Idempotent Consumer | How can a message receiver deal with duplicate messages? | Image Modified | Transactional Client | How can a client control its transactions with the messaging system? | Image Modified | Messaging Gateway | How do you encapsulate access to the messaging system from the rest of the application? | Image Modified | Service Activator | How can an application design a service to be invoked both via various messaging technologies and via non-messaging techniques? |
System Management Image Modified | Wire Tap | How do you inspect messages that travel on a point-to-point channel? |
