Introduction

Introduction As Mirth Corporation says on their web-site, “Mirth Connect is the Swiss Army knife of

healthcare integration engines, specifically designed for HL7 message integration. It

provides the necessary tools for developing, testing, deploying, and monitoring interfaces.

And because it’s open source, you get all of the advantages of a large community of users

with commercial quality support.”

In addition, “The 2012 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.

The focus of this book is to introduce readers to version 3.x of Mirth Connect to the

point that they confident enough to start building their own healthcare data exchange

interfaces.

As you read this book, you will be implementing a fictitious Eligibility Query Service. Each

connection point (channel) 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 3.0.0.6931 version of the product.

Consequently, other releases may include new features, or features used in this book

may change or disappear. You may also notice some 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

explains things in a more detailed and organized way.

In a book of this size, I cannot cover every feature that Mirth Connect v3.x or previous

versions have; consequently, I assume you already have some familiarity with Mirth

Connect.

9 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, XML Schemas, XPath, XSL

Transformation and SOAP/WSDL.

Before you start reading this book, you should have a basic knowledge of JavaScript and

Java; MS Access and PostgreSQL databases from a database administrator perspective;

and are familiarity with operating system environment variables settings.

You should also have basic knowledge of HL7, the standard that is being used to

exchange healthcare data, both version 2 and version 3.

Who should not 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 associated with Mirth Connect v3.0. This book is

not intended to be a step-by-step comprehensive guide or substitute of any kind to

original training and certification programs provided by Mirth Corporation.

This book is also not a tutorial on a specific messaging or middleware technology

implementation. 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

CHAPTER 1 Getting Started

CHAPTER 2 What is a Channel?

CHAPTER 3 Creating a Channel

15 PART I – MIRTH CONNECT BASICS

CHAPTER 1 Getting Started

Getting Started his chapter outlines the Mirth Connect basic installation procedure. All examples in

this book are based on the Windows version of Mirth Connect v3.0, available to

download at http://www.mirthcorp.com/community/downloads

Make sure your computer meets minimum system requirements before you start:

Sun Java JRE 1.5/5.0 or newer;

1 GB of RAM is recommended;

A web browser.

Installation

There are two possible ways to install Mirth Connect based on what package you have

downloaded or what package is available on the website. In one case, the package is an

archive of all files and classes that you need to run Mirth Connect on your computer. You

simply unzip and copy the package to an appropriate folder, for example to the

C:\Program Files\Mirth Connect\. In the other case, there is a GUI based installer that

you just start and go through the steps in the installation wizard. The installation process

itself is quite straight forward.

In both cases what is installed are 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 will be used by the Mirth Connect Server. By

default it is 8080 for unsecure communication and 8443 for the SSL connection. You can

change it later using the Mirth Connect Server Manager.

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;

Type admin for the user name and repeat admin as the password, click Sign in.

If you see the Dashboard statistics page with, most likely, no channels available, you have

successfully done the installation and ready to continue.

Configuration

The Mirth Connect Server Manager can be used as a single point to launch Mirth

Connect Service, configure ports, allocated memories, and database connections.

However, a fully-fledged configuration description is beyond the scope of this book.

Here is only a recommended step is to add a path to the \custom-lib folder to the

operating system’s CLASSPATH environment variable. This is the folder where you put

your Java classes, libraries and other required files.

Versions 1 and 2 of Mirth Connect were using port 1099 for viewing statistics though the

JMX (Java Management Extensions) and RMI (Remote Method Invocation) interfaces.

This port is no longer used in version 3. Hence, if any of your applications or firewall is

utilizing ports 8080 or 8443 you can either change Mirth’s ports using Mirth Connect

Server Manager or manually modify the configuration file located in

\conf\mirth.properties. Don’t forget to restart the Mirth Connect Server or Service for

any changes to make effect.

Mirth Connect Administrator

The Mirth Connect Administrator is a Java application that is not explicitly installed on a

local computer by default in a distributed environment. It is downloaded from the Mirth

Connect Server. The reason for this is to ensure the Mirth Connect Administrator

matches version of the Mirth Connect Server.

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 the Mirth Connect Administrator;

Click Ok to open the webstart.jnlp;

Type admin for the user name and repeat admin as the password in the Mirth

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 areas of information:

http://www.mirthcorp.com/.../mirth/Mirth+Connect+FAQ


Channels status and statistics - the number of messages Received, Filtered,

Queued, Sent, and Errored. The Dashboard Tasks area on the navigation bar on the

left side has menu items essential for developing channels such as Refresh, Send

Messages, and Remove All Messages. Same menu items can be accessed faster by

right clicking on a channel row.

Logs – Server Log and Connection Log. The former - Server Log - is used a lot to

debug channels 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 and therefore closing and opening

the Mirth Connect Administrator brings back all entries not previously explicitly

purged. To clear the Server Log click Clear Displayed Log under the Server Log or

Connection Log area.

Logging Level

Channel’s log level can be configured manually by changing \conf\log4j.properties

entries. Available options are: ERROR, WARN, INFO, DEBUG, and TRACE with DEBUG

selected by default. Log levels may be configured separately for filters, transformers,

postprocessors and other scripts that are explained later in this book.

FIGURE 1-1 Mirth Connect Administrator window by default

Familiarize yourself with other navigation items and tabs since this is the main tool used

to develop channels throughout this book.


CHAPTER 2 What is a Channel?

What is a Channel? he Channel is an essential part of Mirth Connect and can be seen as one-to-many

abstract unidirectional pipes to 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 flex ibility for

dependency, maintenance and/or performance. Some of the processing tasks can even

be external to Mirth Connect and developed independently.

FIGURE 2-1 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. Similarly, the connector that sends outbound messages

is called the 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 Destination connector and transforming the data

representation. Deciding 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 message;

Type and format of the outbound message(s);

T


Mapping table(s) between inbound and outbound messages (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);

PDF and RTF documents;

JMS;

FTP/SFTP;

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

SMTP;

SOAP (over HTTP).

The connector receiving the data is called a Reader, for example the MLLP Reader. The

connector sending the data is called a Writer, the Database Writer as an example.

Connector types are configured under Source and Destination tabs of the Channel, which

is explained later in this chapter. As should be obvious, some settings are common

across all connectors while others are unique to a specific connector type.

If you need a connector that is not shipped with the Mirth Connect installation package,

you can develop your own one (such as a custom HTTPS connector). Some templates

and developer’s level documentation for such development are in the chapter dedicated

to Mirth extensions.

Filters

In a real world scenario, when numerous applications and channels are connected, a

channel may receive messages from several sources and these messages may have to be

processed differently, based on the message type or other criteria.

There are two paradigms for solving this problem, a Router and a Filter:


Router connects to multiple outbound channels. The key benefit of the Router is that

the decision criteria for the destination(s) of a message are maintained in a single

location.

Filter, this is what Mirth Connect uses, is built into a message processing mechanism

and is responsible for determining whether the message should be processed or not.

The Filter inspects message properties (segments or elements) without removing the

message from the message queue. If the message cannot be consumed by this

particular pipe, it is returned to the queue unchanged for another pipe to filter or

process.

Filters can be as simple as specific elements comparison against a hard coded value or as

complex as JavaScript scripts and external Java classes. Filters can also be omitted

allowing all messages to pass through.

If a single channel needs to process more than one type of message, you can create any

number of separate pipes – Destinations - and specify none, one or more filters for each

of them.

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.

How do we communicate data using different formats then? In Mirth Connect this is

done by a message Transformer that translates one data format into another. As a result,

a destination application expects to receive messages it understands which can be

processed and stored in the application’s internal data format.

Mirth Connect allows message translation to occur at different levels, and to chain

message transformers to achieve a required result.

Supported transformers are:

Message Builder maps segments of the inbound message to segments in the

outbound message.


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

These variables may be used later.

External Script, as the name suggests, employs external JavaScripts to transform or

map the data.

XSLT Step utilizes the XSL transformation.

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 enhance the message processing

logic. Scripts apply to a channel itself and all messages that are passing through.

These 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 deals with a message in a native format and allows extracting a

part of the message to store as an attachment or to irrevocably modify a message.

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 are the main places where you handle the inbound and

outbound messages.

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

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

Shutdown 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.

Scripts are performed in the following order:

1. Global Deploy script;

2. Deploy;

3. Attachment script;

4. Global Preprocessor script;

5. Preprocessor script;

6. Source connector Filters script;

7. Source connector Transformer script or mapping;

8. Destination 1 connector Filters script;

9. Destination 1 connector Transformer script or mapping;

10. Destination N connector Filters script;


11. Destination N connector Transformer script or mapping;

12. Response 1 Transformer script or mapping;

13. Response N transformer script or mapping;

14. Postprocessor script;

15. Global Postprocessor script;

16. Shutdown;

17. Global Shutdown script.

When you create a channel, by default, all scripts are empty and do nothing.

Deploy and Shutdown scripts are performed only once, when a channel is deployed or

undeployed, respectively. It is important to note that Global Deploy and Shutdown

scripts are also executed every time a channel is redeployed.

All other scripts are performed every time a message is sent through a channel or an

acknowledgement is received. Notice that the Global Preprocessor script is executed

before the channel’s Preprocessor script is executed. Similarly, after the channel’s

Postprocessor script completes, the Global Postprocessor script is run.

Next, we will explore each of these steps in detail.
