Transport Layer (Inbound)The first step for the message into the ESB is the inbound transport layer which is responsible for handling communication with the service client endpoint.

Supports a variety of communication protocols, HTTP(S), JMS, EJB, FTP, eMail (SMTP/POP/IMAP), TUXEDO, File, Custom Developed

Proxy Service

Proxy services are the ESB's definitions of intermediary Web services that are hosted locally on the bus.

With message brokering, service clients exchange messages with the intermediary proxy service instead of directly with a business service.

A proxy service can have an interface that is identical to a business service with which the proxy service communicates, or the proxy service can have an interface that differs from that of the business service.

Since a proxy service can route messages to multiple business services, you can choose to configure a proxy service with an interface that is independent of the business services with which the proxy service communicates. In such cases, you would configure a message flow definition to route a message to the appropriate business service and map the message data into the format required by the business service's interface.

Message Flow

Message Flows are the definitions of the ESB's proxy services. Pipelines, branch nodes, and route nodes define the implementation of proxy services.


Message Flow

• Conditions/branches• Routing destinations• Request/response Pipelines• Actions:

• Update/replace/delete message contents• Update message headers• Call another service• Raise error on client• Generate a report or alert• Invoke a Java class or EJB

• Error handlers
