Introduction

Introduction

Introduction As Mirth Corporation says on their web-site, website, “Mirth “Mirth Connect is the Swiss Army knife of healthcare integration engines, specifically designed for HL7 message integration. It provides provide s the necessary tools for developing, deve loping, testing, t esting, deploying, depl oying, and monitoring interfaces. And because it’s open sou rce, you get all al l of the advantages adva ntages of a large community co mmunity of users with commercial quality support. support.”” In addition, “ The 2014 HL7 Interface Technology Survey Results ” show that Mirth Connect is one of the fastest growing healthcare messaging platforms due to its open-source paradigm, and robust functionality for HL7 messaging and X12 documents. Mirth Connect also speeds up the development of interfaces for data exchange across different formats and diverse healthcare systems environment. environment. This book describes version 3.x of Mirth Connect to the point that reader are confident enough to start building their own healthcare data exchange interfaces using a new set of HL7 standards called FHIR (Fast Healthcare Interoperability Resources). As you read this book, you will be implementing a number of fictitious FHIR related services. Each connection point (channel and destination) is explained in a separate chapter, which in turn provides step-by-step instructions on how to create and code data transformation rules. This book is written using Mirth Connect version 3.4.0.8000. Consequently, other releases may include new features, and features used in this book may change or disappear. You may also notice differences between screen shots provided in the book and those you see when using Mirth Connect.

Who is this book for? I wrote this book primarily for application developers and system integrators who have found the online Mirth Connect documentation lacking and needed a guidebook that covers covers topics in a mor e detailed detailed and organiz o rganized ed way. A book of this size cannot cover every feature in Mirth Connect v3.x; consequently, I assume you already have some familiarity with its main components, functions and use.

Introduction

Assumption This book assumes that you are dealing with applications that use message-oriented middleware products and expects that you have at least a minimal understanding of Web service technologies including, but not limited to, XML, JSON, REST and OAuth. Before you start reading this book, you should have a basic knowledge of Mirth Connect development paradigm, JavaScript, Java and E4X objects; and are familiar with operating system environment environment variable settings. You should also have basic knowledge of HL7, the standard that is being used to exchange exchange healthcare data, both version 2 and FHIR.

Who should not n ot read this book? As mentioned earlier, the purpose of this book is to provide the reader with a high -level overview of the capabilities and features in Mirth Connect v3.x. This book is not intended to be a step-by-step comprehensive guide or substitute of any kind for training and certification certification programs provided by Mirth Corporation. This book is also not a tutorial on a specific messaging or middleware technology. All examples included in this book are for illustrative purposes only. If you are interested in learning more about a specific technology or product, please refer to one of the many on-line resources, or trainings and certifications provided by Mirth Corporation or its affiliates. This book does not cover any specific installation, configuration, deployment or monitoring activities for system administrators.

CHAPTER 1 Mirt Mirth h Connect Basics

Mirth Connect Basics his chapter outlines the Mirth Connect installation procedure and basic concepts. All examples in this book are based on the Windows version of Mirth Connect v3.3, available available for downloading at h ttp://www.mirthcor ttp://www.mirthcorp.com/communit p.com/community/downloads y/downloads Make s ure your computer comput er m eets minimum system sys tem requirements before you start: 

Oracle JRE version 1.7 or higher;



1 GB of RAM is recommended;



A web browser.

Installation You can install Mirth Connect in either of two ways based on which package you downloaded or which package is available on the website. In one case, the package is an archive of all files and classes you need to run Mirth Connect on your computer. You simply unzip and copy the package to an appropriate folder, for example to C:\Program Files\Mirth Connect\ . In the other case, there is a GUI GUI based wizard that you start to

go through the steps in the installation. The installation process itself is quite straight forward. Both methods install Mirth Connect Server, Mirth Connect Server Manager, Mirth Connect Administrator and Mirth Connect Command Line Interface. During the installation you have to decide which port is used by the Mirth Connect Server. The default is 8080 for unsecure communication and 8443 for the SSL connection. You can change the ports later using the Mirth Connect Server Manager, if necessary. To verify the installation: 

Launch the Mirth Connect Server either through the Mirth Connect Server Manager or the Mirth Connect Command Line;



Open the web browser and type localhost:8080 in the address bar;



Click the Access Secure Site button in Web Dashboard Sign In launch In launch page;



Type admin for the user name n ame and repeat r epeat admin as the password, click Sign in. in.

If you see the Dashboard statistics page with, most likely, no channels available, you have successfully installed Mirth Connect and are ready to continue. If not, refer to Mirth Connect 3.1 User Guide written by “the “the same Mirth technical experts who developed the software” software” available at - http://info.mirth.com/Connect_Documentation_Download.html PART I – GETTING STARTED

12

Configuration The Mirth Connect Server Manager can be used as a single point to launch Mirth Connect Service, configure ports, allocate memories, and to establish database connections. However, a fully-fledged configuration description is beyond the scope of this book. As a recommended option, add a path to the \custom-lib folder in the operating system’s CLASSPATH environment variable. This is the folder where you put Java classes, libraries libraries and other required files th at Mirth should be working with. If any application on your computer or firewall uses ports 8080 or 8443 you can either change Mirth’s ports by using Mirth Connect Server Manager or by manually modifying the configuration file located in \conf\mirth.properties . Don’t forget to restart r estart the Mirth Connect Server or Service to activate your changes.

Mirth Connect Administrator The Mirth Connect Administrator is a Java application that, by default, is not explicitly installed on a local computer in a distributed environment. It is downloaded from the Mirth Connect Server. This ensures the Mirth Connect Administrator matches the version of the Mirth Connect Server Server being us ed. To download the Mirth Connect Administrator: 

Start Mirth Connect Server if it is not already running as a service;



Open the web browser;



Type localhost:8080 in the address bar;



Click Launch Mirth Connect Administrator in in the Mirth Connect C onnect Administrator Administrator launch launch page;



Click Ok to to open webstart.jnlp ;



Type admin for the user name and repeat admin as the password in the Mirth Login. Connect Login pop-up window, then click Login.

If everything is done correctly, each time you login, you will see the Dashboard as the initial screen. The Dashboard displays two information panels: 

Channels status and statistics – shows the number of messages Received, Filtered, Queued, Sent, and Errored. The left sidebar of the Dashboard has tasks panel, with menu options related to your current activity. For example, when you are developing a channel, menu options such as Refresh, Refresh, Send Messages, Messages, and Remove All Messages

13


are displayed. These menu items can be also accessed by right clicking on a channel name in the Channel List. 

Logs – Server Log, Log, Connection Log and Log and Global Maps. Maps. The Server Log is used to debug channel development. Double-clicking on a Server Log entry brings a pop-up window where you can view and copy the entire log entry content. The Server Log is stored by Mirth Connect Server in the database; closing and opening the Mirth Connect Administrator brings back all entries not explicitly purged. To clear the Server Log click Clear Displayed Log under Log under the Server Log or Log or Connection Log area. Log area.

Familiarize yourself with other navigation items and tabs since this is the main tool used to develop and configure channels throughout this book.

Channels The Channel is an essential part of Mirth Connect and can be seen as one-to-many abstract unidirectional pipes that decouple components from each other to transfer healthcare data between two or more applications. The channel architecture implemented in Mirth Connect can divide a large message processing task into a sequence of smaller independent steps. This affords developers the flexibility for dependency, maintenance and/or performance. Some of the processing tasks can even be external to Mirth Connect and developed independently.

FIGURE 1-1 Mirth Connect abstract channel architecture

In general, each channel consists of inbound and outbound Connectors, Filters and Transformers. The connector that receives inbound messages from the Sending Application is called the Source. Source. Similarly, the connector that sends outbound messages PART I – GETTING STARTED

14

is called the Destination. Destination . From the Source connector, data is passed through the channel, where filters and transformers perform operations on the data, for example, routing a message to one or another Destinations connector and transforming the data representation. Deciding each channel’s tasks is when wearing an analyst's hat comes into play. Before you create a new channel, you need to elicit the following requirements: 

Type of Application the channel reads data from (Source connector type);



Type of Application the channel sends data to (Destination connector type);



Type and format of the inbound inbound message;



Type and format of the outbound message(s);



Mapping Mapping table(s) betw een een inbound and outboun o utbound d messages mess ages (Transformation). (Transformation).

Connectors In terms of Enterprise Integration, the connector is a Message Endpoint that specifies a particular way or, more accurately, a particular protocol Mirth Connect should use to communicate with an external application or another Mirth Connect channel. Mirth Connect supports sending and receiving messages over a variety of connectors listed here in no particular order: 

TCP/MLLP;



Database (MySQL, PostgreSQL, Oracle, Microsoft SQL Server, ODBC);



File (local file system and network shares);



FHIR;



PDF and RTF documents;



JMS;



HTTP (note that HTTPS is not supported in the free version);



SMTP;



SOAP (over HTTP).

The connector that receives the data is called a Reader , for example e xample the MLLP Reader. The connector that sends the data is called a Writer , the Database Writer is an example. Connector types are configured under Source and Source and Destinations tabs Destinations tabs of the channel. Obviously, some settings are common across all connectors while others are unique to a specific connector type.

15


You can develop your own connector if you need one that is not shipped with the Mirth Connect installation package, e.g., HTTPS connector. However, this is out of scope of this book.

Filters In a real world scenario, when numerous applications and channels are connected, a channel may receive messages from several sources and may process these messages differently, based on the message type or other criteria. There are two paradigms for addressing this requirement, a Router and and a Filter : 

Router connects Router connects to multiple outbound channels. T he key benefit of the Router is that the decision criteria for the destination(s) of a message are maintained in a single location.



Filter, Filter, this is what Mirth Connect uses, is built into a message processing mechanism and determines whether or not the message should be processed. The Filter inspects message properties (segments or elements) without removing the message from the message queue. queue. If the t he message cannot be consumed by this pa rticular rticular pipe, pipe , it is returned to the queue unchanged for another pipe to filter or process.

Filters can be as simple as comparing specific elements against a hard coded value or as complex as a scripting language routine. Filters can also be omitted allowing all messages to pass through. Some routing capabilities have been introduced in Mirth Connect v3.1 by using a "destinationSet". If a destination is removed from the destination destination set, this destination will not receive the message. If a single channel needs to process more than one type of message, you can create any number of separate pipes – Destinations Destinations - and specify none, one or more filters for each pipe.

Transformers More often than not, messages are sent between legacy systems, custom applications and third-party solutions, each of which is built around a proprietary data model. Even systems that claim to support a single standard may place specific requirements on data format and content. If we could bring all legacy systems to a single format when a new business requirement is proposed, we would avoid conversion issues. Unfortunately, for most legacy systems, data format, content or data sequence changes are difficult and risky, and simply not feasible.


16

How do we communicate data using different formats then? Mirth Connect does this in a message Transformer that translates one data format into another. As a result, a destination application can receive messages it understands and which can be processed and stored stored in i n the application’s applica tion’s internal data format. Mirth Connect allows message transformation to occur at different levels and to chain message transformers to achieve a required result. Supported transformers are: Message Builder maps Builder maps segments of the inbound message to segments in the



outbound message. Mapper maps Mapper maps segments of the inbound message to internal Mirth Connect variables.



These variables may be used later. External Script, Script, as the name suggests, employs external JavaScript routines to



transform or map the data. 

XSLT Step utilizes Step utilizes the XSL transformation.



JavaScript, JavaScript, along with External Script, is where flexibility comes into play. Here any type of (Rhino) Java Script and Java code can be used.

Scripts Channels also support unique features called Scripts to Scripts to enhance message processing logic. Scripts apply to a channel itself and all messag messag es that are passing through. These scripts scripts are: 

Deploy script is executed each time Mirth Connect Server starts or a channel is redeployed. This is the best place to initialize variables or create class objects.



Attachment script Attachment script deals with a message in a native format and allows extracting part of the message to store as an attachment or to irrevocably modify a message.



Preprocessor script Preprocessor script also allows handling each message in a native format before Mirth Connect starts translating it into the internal format, which is XML.



Filter & Transformer scripts Transformer scripts are the main places for handling the inbound and outbound messages.



Response script, as the name suggests, handles handles the response sent by a destination.



Postprocessor script Postprocessor script is executed after the message has been successfully sent.



Undeploy script Undeploy script is launched each time Mirth Connect Server stops. This is the place to, for example, release memory that was allocated for the classes used by the channel.

17


Mirth Connect uses JavaScript as a scripting language with the ability to extend it by calls of external Java classes. The latter may be one of those included to the Mirth installation package package or user d efined. efined. Besides the channel level, Mirth Connect employs Global Scripts that play the same role as channel scripts and help in separating the business logic. They have the same Deploy , Undeploy , Preprocessor and and Postprocessor scripts; scripts; the only difference is that they apply to all channels. This concludes Mirth Connect introduction section.
