actually denotes JMS queues or topics.
TCP/IP HL7 Features
The TCP/IP HL7 Adapter includes the following features:
Bidirectional processing, including client or server mode in either direction (to or from Sun
Java CAPS ESB).
Handles both HL7 HLLP and MLLP protocols and envelopes.
Provides a wide variety of recourse action congurations.
Non-blocking I/O.
Recovery and retry logic.
Debug levels and error logging.
Journaling of HL7 messages and associated acknowledgements.
HL7 acknowledgement levels.
Fully supports the HL7 sequence numbering protocol.
Full support for HL7 ACK and NAK generation and validation.
Supports delayed ACK in both directions.
TCP/IP HL7 Adapter Components
The TCP/IP HL7 Adapter incorporates three components:
The HL7 TCP/IP Resource Adapter that implements the lower layer HL7 protocol over
TCP/IP.
Default inbound and outbound Collaborations that implement the HL7 messaging
protocol, sequence numbering, and recourse actions.
Generic HL7 Message Libraries that provide the structures necessary to parse and create the
data messages and ACKs used by the protocol.
The TCP/IP HL7 Message Library, also known as an Object Type Denition (OTD) Library,
enables the creation of HL7 interfaces capable of running over TCP/IP, and also utilizes the
common Adapter services available in Java CAPS. The TCP/IP HL7 Adapter works hand in
hand with the Sun Java CAPS HL7 Message Libraries, versions 2.1 through 2.5.1.
The TCP/IP HL7 Adapter properties allow the user to easily congure the operation of the
TCP/IP HL7 Adapter. The Adapter includes a set of properties that are congured in the
Connectivity Map and only apply to that Adapter in the Project. It also includes a set of
properties that are congured in the Environment and apply to all TCP/IP HL7 Adapters in the
Project. These properties are adopted into the Message Library’s functions.
