GlassFish ESB v2.1, MySQL v5.1 – Make HL7 v2.3.1 Delimited Messages from Custom Delimited Records with HL7 Encoder and HL7 BC

By Michael Czapski Sun 5 Comments »

“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 document: 02_PatientSvc_MakeHL7v2DelimDataFromCustomDelimRecords_0.4.pdf

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.

Quick Note 003 for JBI-based JMS Publisher and Subscriber example for Leonard Barkley

By Michael Czapski Sun 1 Comment »

This Quick Note discusses a simple solution to the use case provided by Leonard Barkley. The question goes like this:

“I dont have any idea how to implement BPEL process but the BPEL deployed as a subscriber of a topic. usually I implement the BPEL process and deployed it as web service.”

We produce a simple GlassFish ESB v2.1-based solution which reads a file, sends its content to a JMS Topic and another simple GlassFish ESB v2.1-based solution which subscribes to the same JMS Topic, receives the message and writes it to a file. Both solutions will use BPEL to implement the simple logic, though it is possible to implement both solutions without BPEL, so we have File BC -> BPEL SE -> JMS BC -> JMS Provider (Topic) -> JMS BC -> BPEL SE -> File BC.

Here is the note: QuickNote003_forLeonardBarkley.pdf

Hire is an archive with the project group containing all the projects developed in the Note: JMSTopicSampleProjGrp.zip

As Leonard Barkley pointed out to me, having implemented the sample, the Note is incorrect on Pages 23 and 24. The JMSSubscriber_JMSIn WSDL should use the Receive type, not Send type as the docuent states. The solution still works, it appears, but the configuration as documented is confusing. Thanks Leonard.

Java CAPS 6/JBI Note 4 – File to File, with Java logic using Java EE SE

By Michael Czapski Sun No Comments »

The attached document explores the ability of Java CAPS 6/JBI and OpenESB to expose and execute Java-based logic as a JBI service. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution that reads an XML record from a text file, invokes java logic that operates on that record then writes the XML response record into a file.

04File2FileJavaEE.pdf

There are errors in pictures on pages 12 and 13. The WSDL name in the pictures does not correspond to the name in the text. This error is corrected in revision 1.1 of the document, 04File2FielJavaEE_1.1.pdf. Thanks to Juraj Kazda for spotting the issue.

Java CAPS 6/JBI Note 3 – File-2-File with CSV to XML Decode/Encode

By Michael Czapski Sun 2 Comments »

The attached document briefly explores the Encoder aspect of Java CAPS 6/JBI and OpenESB. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution that reads comma-delimited record from a text file, ‘decodes’ then into XML and writes the XML-equivalent records into a file. The project is then extended to ‘encode’ XML records back to CSV format on output.

The focus is the practice of using JBI components not the theory of JBI.

This document addresses the integration solution developers, not developers of Service Engines or Binding Components.

The project uses JBI components only, that’s why it is just as good for OpenESB exploration as it is for Java CAPS 6/JBI exploration.

JBI (Java Business Integration) is not discussed to any great extent. JBI artifact names are used in discussion but not elaborated upon. Explanations are provided where necessary to foster understanding of the mechanics of developing integration solutions using JBI technologies in OpenESB and Java CAPS 6/JBI.

Java CAPS 6 and OpenESB are two of a number of toolkits that implement the JBI specification (JSR 208). When I use an expression like “In JBI …” I actually mean “In JBI as implemented in Java CAPS 6 and OpenESB …”. The same things may well be implemented differently in other JBI toolkits.

Java CAPS 6 “Revenue Release” is used and shown in illustrations. OpenESB can be used instead however the appearance of components shown in illustrations may vary somewhat.

I use Windows to develop these solutions and make no effort to verify that the solutions will run on other platforms.

The complete walkthrough is here.

Java CAPS 6/JBI Note 2 – Basic File-to-File projects with multi-record files

By Michael Czapski Sun No Comments »

This document is intended to help you get over the initial hurdles of exploring Java CAPS 6/JBI and OpenESB. It walks through the process of creation, deployment and execution of a simple File-to-File integration solution, and a simple File to BPEL Process to File solution, with detailed step-by-step illustrations. Both solutions use inbound files with multiple records. The focus is the practice of using JBI components not the theory of JBI. This document addresses the integration solution developers, not developers of Service Engines or Binding Components.

Java CAPS 6/JBI Note 1 – Basic File-BPEL-File Project

By Michael Czapski Sun 1 Comment »

As implemented in OpenESB and Java CAPS 6/JBI, JBI at first put me off completely. I had no idea where to start and what to do. This was particularly annoying as I was reasonably effective in developing solutions using Java CAPS 5.x and did not look forward to trying to figure out how to do in OpenESB the same thing I already new how to do.
