To develop HL7 v2 messaging solutions which use the SOA Suite for healthcare integration one needs a working development and deployment environment.

This article provides references to components which must be obtained and installed to get a working environment in preparation for development of solutions presented in possible future articles.

This article and the remaining articles assume a development environment based in Microsoft Windows XP 64-bit. Nothing, except the instructions for downloading Windows-specific components and screenshots of Windows-specific non-SOA Suite tools, prevents you from developing on any of the other supported platforms. Convers my Windows-specific instructions to your platform-specific instructions as needed.

I notice that people used to the eGate/Java CAPS way of doing things, when looking at migrating to the SOA Suite for HL7 messaging, are trying to reproduce the pattern “HL7v2Adapter?JMS Queue”. This is not necessary when using SOA Suite but can be done if one insists. This article walks through the process of implementing this pattern using Oracle SOA Suite 11g R1 PS3.

The process will follow these steps:
1. Obtain and configure the QBrowser tool for JMS browsing
2. Obtain and configure the HL7 Sender tool
3. Create two WebLogic JMS Queues to be used in the solution
4. Create and deploy a HL7 v2 Inbound Trading Partnership Agreement
5. Submit HL7 v2 messages and inspect them in the corresponding JMS Queue
6. Repeat steps 4 and 5 for another inbound stream

The cmplete article, which can be found at, will demonstrate that Oracle SOA Suite B2B HL7 infrastructure can be configured to receive message streams over multiple inbound MLLP channels and deliver each stream to a distinct JMS destination, much as eGate and Java CAPS solutions used to do.

WebLogic Server does not include a convenient tool to browse JMS destinations. Freely downloadable QBrowser version 2 tool, with some configuration, can be used to provide easy to use functionality to work with WebLogic JMS destinations. This article discusses how QBrowsers should be configured to work with the JMS destinations managed through the WebLogic Server 11g (10.3), which was the current version at the time this article was written.

The Oracle SOA Suite 11g R1 B2B functionality can be used for HL7 v2.x delimited messaging, both inbound and outbound. I have a series of articles which provide step-by-step instructions for developing HL7 v2.x delimited messaging solutions for processing inbound and outbound messages, with varying ACK patterns –

This article discusses how an A19 Query processing solution can be implemented using the SOA Suite 11g R1 PS3.
We have a client sending a HL7 v2.3.1 A19 QRY request, asking for demographic details for a patient specified by an ID. The HL7 v2.3.1 A19 ADR response will carry a PID segment with basic demographics. The client identifies itself with MSH-3 (Application ID) of “A19QRY” and MSH-4 (Facility ID) of “CLI1”. The query processor is identified by the client with MSH-5 (Application ID) of “A19ADR” and MSH-6 (Facility ID) of “GWYQ”.

In any but the simplest of HL7 messaging environments there will be multiple sources and multiple destinations of HL7 messages. It is very unlikely that all, or even a majority of these, will use exactly the same HL7 message structures in terms of versions, optional/mandatory segments, extension Z segments, and so on. A sensible approach to dealing with these kinds of issues, and a key component of the HL7 Enterprise Architecture, is the so called Canonical (or Common) Message Model (CMM). The CMM works hand-in-glove with the enterprise architecture in which transformation to/from the CMM is performed at the edges of the integration domain. This article discusses major considerations and works through the mechanics of deriving a Canonical Message Model for a fictitious Healthcare Enterprise and implementing it using the Oracle SOA Suite 11g HL7 tooling as an example. The article will also discuss and illustrate a mechanism for injecting arbitrary metadata into the canonical message, generated by the B2B Document Editor, in such a way that it is ignored by the Edge-dwelling B2B infrastructure but is significant to the SOA infrastructure.

This article is of potential interest to these Sun/SeeBeyond customers who have an investment in moderate and large Java Collaboration Definition-based transformation and mapping rules, and who are looking for ways to reuse as much as possible of the Java code involved, when migrating to the Oracle SOA Suite. The example developed in this article comes from the healthcare domain and uses the HL7 OTDs (Object Type Definitions). This is a deliberate choice because all but the most trivial HL7 transformations will involve hundreds of lines of Java code, therefore are a good candidates for migrating to the SOA Suite Spring Component as means of preserving the code and the effort invested in developing it. This does not make the method domain-specific. On the contrary, the method is applicable to all other domains where JCDs with significant transformation and mapping rules content are used.

Discussion in this article addresses a subset of technologies available in the Java CAPS and in the SOA Suite. Specifically, the Java Collaboration Definitions supported in Java CAPS 5.x and in Java CAPS 6/Repository, and the Spring Component supported in the SOA Suite 11g R1 PS2. Both use the Java programming language and related runtime environment to implement processing logic.  There is no discussion pertaining to JBI-based technologies or Java CAPS BPEL-based technologies. There is no discussion about other ways in which Java logic can be deployed as part of a Oracle SOA Suite solution.

The HL7 eWay and JCD based Java CAPS solution will be ported to the Oracle SOA Suite 11g B2B and Mediator-based environment. HL7 Adapters will be replaced with the Oracle “Healthcare Adapters”, provided by the SOA Suite B2B HL7 support infrastructure. Routing will be provided by the Mediator component and transformation logic will be ported to the Spring Component.

This article walks through the process of “extracting” JCD source and related archives from Java CAPS, developing a stand-alone Java application which uses the JCD source, encapsulating JCD source in a Spring component and finally reproducing Java CAPS HL7 solution functionality in an equivalent SOA Suite solution.

In this article I discuss and illustrate a “SOA-less” solution in which the Oracle SOA Suite 11g R2 B2B receives a stream of different HL7 v2 delimited messages types (A01 and A03) using a single inbound adapter. The messages are converted into their “equivalent” HL7 v2 XML messages. I say “SOA-less” because all the work is done entirely within the B2B part of the SOA Suite – no OSB or SOA Composites are involved.

This article demonstrates one way in which different message types can be accepted through one inbound adapter.

This article is a follow on to the “Oracle SOA Suite 11g HL7 Inbound Example – Functional ACK Addendum” article and the “Oracle SOA Suite 11g HL7 Inbound – Customized HL7 Message Structure and Data Validation” article.  In these articles the B2B infrastructure was configured to return the “Functional ACK” when it validated each message. The ACK was a positive or a negative ACK depending on whether the message passed validation. The ACK was generated by the B2B Layer before the message was passed on to the SOA Layer.

In this article I expand on the previous posts by configuring the B2B Layer to pass the message to the SOA Layer and pass the Functional ACK, generated by the SOA Layer on to the requester. To process a message and produce the ACK we will build and deploy a new SOA Composite.

Messages we used in previous articles dealing with HL7 Inbound (Oracle SOA Suite 11g HL7 Inbound Example – Functional ACK Addendum, Oracle SOA Suite 11g HL7 Inbound Example) were not strictly speaking valid according to the default HL7 V2 ADT A01 message specification produced by the Oracle B2b Document Editor. Both the message structure was not quite right and the data was not quite right. To allow such messages in, we disabled Validation property in the B2B Trading Partnership Agreement.

In this article we will alalyze the data and  create a customized HL7 v2 ADT A01 structure which will allow us to successfully validate incoming messages. We will then modify the document definition and Partnership Agreements to use this custom structure and validate messages as they come in.

The customization discussed in this article only scratches the surface of what is possible with the Oracle B2B Document Editor.
