“Progress” notwithstanding, Healthcare environments still extensively use the HL7 v2.x Delimited messages for conveyance of patient and patient-related information between applications. The GlassFish ESB provides support for HL7 v2.x messaging in the form of the HL7 Encoder, which allows conversion between HL7 v2 Delimited and HL7 v2 XML message formats, and in the form of the HL7 Binding Component, which allow connectivity between the GlassFish ESB-based healthcare solutions and healthcare applications that support HL7 over TCP connectivity.

In this document I will walk through the process of generating HL7 v2.3.1 delimited messages from pipe-delimited records containing patient information, sending and receiving HL7 v2.3.1 delimited messages using the HL7 Binding Component, parsing HL7 v2.3.1 delimited messages and writing HL7 v2 delimited messages to a file. To create and process HL7 messages I show how create a custom ADT A04 XML Schema and a custom “any HL7 v2 message” XML Schema. This gives me an opportunity to use the File Binding Component (File BC), the HL7 BC, the HL7 Encoder, the Custom Encoder and the BPEL Service Engine (BPEL SE). This also gives me an opportunity to demonstrate a HL7 v2.3.1 delimited message sender solution and to demonstrate a HL7 v2.3.1 delimited message receiver solution. At the end of the process we will have a file containing HL7 v2 delimited ADT A04 messages, which we will use in related writeups.

Here is the companion archive containing input files, the output file and the projects: 02_PatientSvc_MakeHL7v2DelimDataFromCustomDelimRecords_data.zip

The writeup document has been updated and version changed to 0.4.
