HL 7 Processor
We will use the HL7 Binding Component, the File Binding Component, the JMS Binding Component, the SOAP/HTTP Binding Component, the BPEL 2.0 Service Engine, the JavaEE Service Engine, the HL7 Encoder and EJB-based Web Services in a JBI-based solution.
In the process we will create XML Schema Documents (XSDs), Web Services Description Language Documents (WSDLs), a BPEL 2.0 Business Process, an EJB-based “Implementation First” web service, an EJB- and WSDL-based “Interface First” web service, a bunch of Composite Applications, BPLE 2.0 mapping, BPEL 2.0-based Web Service orchestration, on-the-fly conversion of HL7 version 2.3.1 delimited messages to their XML equivalents. We will get a pretty good exposure to what OpenESB and Java CAPS 6/JBI components look like, how they work and how they can be used to create real business solutions. Above all, we will develop and test a solution that is more sophisticated then the customary “Hello World” examples but not so complex as to take too long to build and become too hard to comprehend by a novice user.
The particular business problem and the particular solution came about because once upon a time there was intent to build a series of related OpenESB projects – HL7 Processor, MDM Processor and IEP Processor that would:
The MDM Processor and the IEP Processor made it to the Sun CEC 2008 as demonstrations, with associated Tutorials by Tom Barrett, and demonstration recordings by me. The HL7 Processor did not make it. With the appearance of Java CAPS 6 Update 1 more JBI components made it into the officially supported Sun product. While the HL7 BC and the HL7 Encoder did not make it into this Update they will, eventually. Both components are already available from the OpenESB site and can be installed into the Java CAPS 6 Update 1 installation as unsupported components. This is what we will do for this Note.
