ITI-22 actors

Endpoint URI Format

The endpoint URI format of the pdq-iti22 component is identical for producers and consumers:


where hostname is either an IP address or a domain name, and port is a number. For the consumer side, the host name allows the access from any remote host. These two obligatory URI parts represent the address of the MLLP endpoint which is to be served by the given consumer or accessed by the given producer. URI parameters controlling the transaction features are described below.

HL7v2 Codec

All HL7v2-based transactions are realized using the camel-mina2 and camel-hl7 components and requires that an HL7v2 Codec is available in the Camel registry.


This is an example on how to use the component on the consumer side:

      // process the incoming request and create a response
