Introduction This document describes how to create a simple HL7 Sender and Receiver
project.
I am assuming you have done some basic OpenESB projects. If you have
not, you may want to try a HelloWorld example in OpenESB first to get
familiar with OpenESB.
The HL7 Sender project polls for files on a file system containing HL7
messages and sends them over MLLP to an HL7 external using the HL7
Outbound port and then writes the acknowledgement back to the file
system.
The HL7 Consumer (Receiver) project connects up the HL7 interface over
MLLP (port 4040) and receives the HL7 messages, converts to XML and
writes the data out to a file in XML format.
To create or use these projects you need an OpenESB installation.
There are other articles for installing OpenESB. I recommend installing
OpenESB V2.3 from the community site:
http://open-esb.net/index.php?option=com_content&view=article&id=113&Itemid=583

Once installed and running, please use the GlassFish admin console to
install the HL7 Binding Component runtime jar from:
https://s3.amazonaws.com/LogiCoy/OpenESB2.3/hl7bc-installer-2.3.0-SNAPSHOT.jar
Choose directory where the HL7 BC jar is, click Open Next Finish
If you would like to import and use the projects instead of creating them
from scratch, please download the zip file from the link below and unzip to
your netbeans project folder:

Create HL7 Sender BPEL Project First, we create the HL7 Sender BPEL project!
Run the OpenESB Netbeans IDE.
Select Projects tab and New Project SOABPEL Module- Enter project
name HL7MsgSender and click Finish

Visit LogiCoy.com
Create WSDLs for the HL7 Sender Project For this HL7 Sender project we need a File and a HL7 WSDL.
HL7MsgSender_FileReceive WSDL:
Input1
Page | 6
Visit LogiCoy.com
Output1
For the File Inbound, file-address, you can specify a File Binding
Component Application Variable instead of hard coding the directory path.
This is a good practice and allows for defining the value to be determined
based on your environment settings on the GlassFish admin server. The
variable name is: ${hl7MsgPollDir}.

Please set an appropriate value for it on the GlassFish admin console.

HL7MsgSender_HL7Send WSDL:
This is the outbound HL7BC WSDL and you need to set appropriate
host/port values, for hl7:address

and hl7:protocolproperties

Now you can edit your HL7MsgSender BPEL process and drag and drop
the FileReceive WSDL to the left side of the BPEL editor and HL7Sender
WSDL to the right.
You can then add partner links!

Create WSDLs for the HL7 Receiver Project For this HL7 Receiver project we need a File and a HL7 WSDL.
HL7MsgConsumer_FileSend WSDL:

Output filename: HL7Msg.xml
For the File Outbound, file-address, you can specify a File Binding
Component Application Variable instead of hard coding the directory path.
This is a good practice and allows for defining the value to be determined
based on your environment settings on the GlassFish admin server. The
variable name is: ${hl7MsgOutDir}.

Test HL7 Sender and Receiver Projects
Create a file with name HL7Msg.hl7 and place it in the inbound file
directory indicated by your FIleBC application variable
${hl7MsgPollDir}, which in this case is \tmp\data and put some HL7
data in it. For example:
MSH|^~\&|SMS|IAH|CERNER|PATHNT|200201291848||ADT^A03|agre|P|2
.3|||AL|NE|
EVN|A01|200201291848|||ABCKB1

PV2|||^SEIZURE, FEVER, RLQ PAIN
Observe, that the file is picked up by the HL7 Sender project , and sent to
the HL7 Receiver project via MLLP protocol and that an acknowledgement
is received and written back to the file system with filename HL7Ack.txt with
the following content:
MSH|^~\&|CERNER|PATHNT|SMS|IAH|200201291848||ACK|agre|P|2.3
MSA|AA|agre
Also, observe that the HL7 Consumer (Receiver) project receives the HL7
message from the HL7 Sender project over MLLP (port 4040) and converts
it to XML and writes the data out to the HL7Msg.xml file in the directory
pointed to by by your FIleBC application variable ${hl7MsgOutDir}.

Conclusion
I hope this tutorial is helpful in your usage of OpenESB for HL7 integration
projects.
Please note that you can substitute your own HL7 Sender or Receiver
external system using any other HL7 compliant tool to communicate and
exchange data with the appropriate OpenESB HL7 project counterpart.
