Migrating Java CAPS 5/6 Assets to Oracle SOA Suite – HL7 JCD to Document Callout Migration

This article leverages discoveries from the 2+ year old article “Migrating Java CAPS 5/6 Assets to Oracle SOA Suite 11g – HL7 JCD to Spring Component Migration”, at http://blogs.czapski.id.au/2010/10/migrating-java-caps-56-assets-to-oracle-soa-suite-11g-hl7-jcd-to-spring-component-migration,  and presents a different method of reusing “HL7 Transformer JCD” code in a SOA or OSB solution. This method uses SOA Suite for healthcare integration, slightly modified Java code for a “HL7 Transformer JCD” and WebLogic JMS. The Java CAPS part of the discussion is substantially the same, except the JCD code is wrapped in a SOA Suite for healthcare integration Callout, rather than being converted to a Spring Component embedded in a SOA Campsite. The “HL7 Adapter” part of the article is different in that SOA Suite for healthcare integration is used instead of the SOA Suite B2B HL7 functionality.
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 or the Oracle Service Bus. 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 migration. The adapter part of the HL7 solution is provided by the SOA Suite for healthcare integration. This makes the method domain-specific.
Discussion in this article addresses a subset of technologies available in the Java CAPS and in the SOA Suite for healthcare integration. Specifically, the Java Collaboration Definitions supported in Java CAPS 5.x and in Java CAPS 6/Repository, and the SOA Suite for healthcare integration (part of the SOA Suite 11g R1 PS5).
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 an Oracle SOA Suite solution.
The HL7 eWay and JCD based Java CAPS solution will be ported to the Oracle SOA Suite for healthcare integration and Java-based environment. HL7 Adapters will be replaced with the HL7 endpoints provided by the Oracle SOA Suite for healthcare integration infrastructure. What minimal routing is used will be provided by the Mediator component via JMS Queues. Transformation logic will be ported to the Java POJO (Plain Old Java Object) and will be embedded in the endpoint as a document callout.
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 SOA Suite for healthcare integration callout and finally reproducing Java CAPS HL7 solution functionality in an equivalent SOA Suite for healthcare integration solution.

SOA Suite for healthcare integration Series – HL7 v2 solution using JMS “the Java CAPS way”

This article may be of interest to these who would like to use the “SOA Suite for healthcare integration” HL7 v2 delimited message handling functionality in solutions similarly to how Oracle Java CAPS HL7 eWay-based solutions were built, perhaps as endpoints in a “Service Bus”-based infrastructure, or to these who would like to use the HL7 messaging handing functionality in OSB environments. In essence, for these unfamiliar with the Java CAPS pattern of use, there were the “Inbound HL7 eWay” and the “Outbound HL7 eWay” patterns. An inbound HL7 v2 Adapter (eWay) would receive a HL7 message, perform all (minimal) validation and acknowledgement processing and store the incoming message in a persistent JMS Queue for some downstream component to process the message as necessary. An Outbound HL7 v2 Adapter (eWay) would read a HL7 message from a JMS Queue (where it was deposited by some upstream component) and send it out to the external system, performing any HL7 ACK processing that might have been required.
In the prior articles in this series we used direct integration between the HL7 v2 endpoints and SOA Suite Composites which provided processing logic. While in my articles JMS is used implicitly as an internal mechanism (via B2B_IN_QUEUE and B2B_OUT_QUEUE JMS queues) the SOA Suite composite did not explicitly use JMS adapters.
It is possible to configure SOA Suite for healthcare integration endpoints in such a way that messages the inbound endpoint receives will be deposited in a particular JMS destination (queue or topic other than the B2B_IN_QUEUE) associated with the endpoint, and messages to be sent by an outbound endpoint will originate in a specific JMS destination (queue or topic other than the B2B_OUT_QUEUE). This will allow such endpoints to be used in Oracle Service Bus-based or other ESB-based solutions as services with JMS interfaces.
In this article we will develop and exercise an inbound-to-JMS and JMS-to-outbound HL7 v2 delimited message processing solutions to demonstrate this capability.

SOA Suite for healthcare integration Series – Implement an A19 Query Processor

While most HL7 v2 messaging is of the store-and-forward kind, where a sender sends a message to a partner, receives a positive acknowledgement and forgets the transaction, there are circumstances where a sender wants to query the receiver and get and process a response. For ADT-related queries A19 transaction serves this function. A client application can send an A19 QRY message, with a patient identifier and assigning authority and request patient demographic information to be returned using the A19 ADR response message.
In this article we will develop and exercise an A19 Query Processor solution.

SOA Suite for healthcare integration Series – Externalise, Repair and Resubmit “Broken” Messages

Every now and then a situation may arise where a message sent to a downstream system is rejected or a message arriving from an external system, is rejected. Some of the possible issue could be “fixable” and others not. If message is “fixable”, in the sense that its content or structure can be modified and the re-submitted modified message will be accepted, then the operator must follow the steps necessary to extract, repair and resubmit the message. In other circumstances it may be necessary to resubmit a specific batch of messages to an external system, for a particular time period or of particular kind.

In this article we will walk through the process of externalizing a message, “fixing” it and resubmitting it for processing. We will also briefly touch on other uses of the resubmit utility.

More details on the technical aspects of this topic can be found in the Oracle “Technical Note: 11g_005 Command-Line Utilities”, section “Resubmit Utility”, available at http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/326860.pdf.

SOA Suite for healthcare integration Series – Domain Value Map (DVM) – On-the-fly Code Mapping

In this article the routing and transformation solution developed in the article entitled “SOA Suite for healthcare integration Series – Routing and Transformation using XSL Solution, will be extended to add an on-the-fly code mapping. This does not have anything to do with HL7 or HL7 processing, or indeed SOA Suite for healthcare integration infrastructure, but since the task is a pretty common one in the HL7 messaging world, it will be discussed and illustrated.

SOA Suite for healthcare integration Series – Creating a Canonical HL7 v2 Message Model

Each different domain, covered by HL7 v2 standard, has a set of message definitions which support message exchanges for a particular domain. Most of the message definitions for a domain share certain segments. Many of the segments are optional and perhaps not used in a particular messaging environment.
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.
It is common for integrating specialists, if the tooling which they use permits, to develop one or few generalised message structures which can be used to represent more than one distinct message from a domain they work with. These are typically called canonical models. The overriding purpose is to standardise the message payload being passed around between integration components, enabling reuse and reducing complexity. The Canonical Message model (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, standardizing as much as possible, payload structure within the integration domain.
The article, whose full text is available at http://blogs.czapski.id.au/wp-content/uploads/2012/09/SOASuiteHCI_ch5_CanonicalMessage_v0.1.0.pdf, works through the mechanics of deriving a Canonical Message Model for the series of articles on SOA Suite for healthcare integration using the “Oracle SOA Suite for healthcare integration” tooling. It contains an abridged version of the article “Healthcare Enterprise – IT Architecture Building Blocks – Canonical Message Model for a HL7 Enterprise”, available at http://blogs.czapski.id.au/2010/10/healthcare-enterprise-%e2%80%93-it-architecture-building-blocks-canonical-message-model-for-a-hl7-enterprise, but adds new material related to testing the canonical structure against sample data and modifying the structure to accommodate data idiosyncrasies.
