This document describes how to create a simple HL7 Sender and Receiver project using 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.

If you havenot, you may want to try a HelloWorld example in OpenESB first to getfamiliar with OpenESB.The HL7 Sender project polls for files on a file system containing HL7messages and sends them over MLLP to an HL7 external using the HL7Outbound port and then writes the acknowledgement back to the filesystem.The HL7 Consumer (Receiver) project connects up the HL7 interface overMLLP (port 4040) and receives the HL7 messages, converts to XML andwrites 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 installingOpenESB V2.3 from the community site:http://open-esb.net/index.php?option=com_content&view=article&id=113&Itemid=583
  • 4. Page | 3Visit LogiCoy.comOnce installed and running, please use the GlassFish admin console toinstall the HL7 Binding Component runtime jar from:https://s3.amazonaws.com/LogiCoy/OpenESB2.3/hl7bc-installer-2.3.0-SNAPSHOT.jarChoose directory where the HL7 BC jar is, click Open Next FinishIf you would like to import and use the projects instead of creating themfrom scratch, please download the zip file from the link below and unzip toyour netbeans project folder:https://s3.amazonaws.com/LogiCoy/OpenESB2.3/Examples/HL7Projects.zip
  • 5. Page | 4Visit LogiCoy.comCreate HL7 Sender BPEL ProjectFirst, we create the HL7 Sender BPEL project!Run the OpenESB Netbeans IDE.Select Projects tab and New Project SOABPEL Module- Enter projectname HL7MsgSender and click Finish
  • 6. Page | 5Visit LogiCoy.comCreate WSDLs for the HL7 Sender ProjectFor this HL7 Sender project we need a File and a HL7 WSDL.HL7MsgSender_FileReceive WSDL:Input1
  • 7. Page | 6Visit LogiCoy.comOutput1For the File Inbound, file-address, you can specify a File BindingComponent Application Variable instead of hard coding the directory path.This is a good practice and allows for defining the value to be determinedbased on your environment settings on the GlassFish admin server. Thevariable name is: ${hl7MsgPollDir}.
