JavaScript Reader

This source connector executes a custom user-defined JavaScript script on a specified schedule. This can be used in a wide variety of ways, such as calling out to external Java libraries or invoking a local OS shell script. You can return a message (or list of messages) to dispatch to the channel, or simply use the script as a scheduled job that doesn't necessarily produce messages. For example, you can use tools like ChannelUtil to programmatically start/stop/deploy channels from within the script.

Source Map Variables

If this connector receives a message from a Channel Writer, the following source map variables will be available: Key Description sourceChannelId The unique ID of the channel that dispatched a message to the current channel. sourceMessageId The ID of the message from which the current message dispatch originated. sourceChannelIds If there are more than two channels in a Channel Writer -> Reader chain, this will be a List containing the IDs of all channels in the chain. sourceMessageIds If there are more than two channels in a Channel Writer -> Reader chain, this will be a List containing the IDs of all messages in the chain.

Connector-Specific Properties

Every connector has its own custom set of properties. The properties you configure for a TCP Listener will be different from a Database Writer and so on. Here is a list of source and destination connectors supported by Mirth® Connect: Source Connectors Channel Reader DICOM Listener Database Reader File Reader HTTP Listener JMS Listener JavaScript Reader TCP Listener Web Service Listener Destination Connectors Channel Writer DICOM Sender Database Writer Document Writer File Writer HTTP Sender JMS Sender JavaScript Writer SMTP Sender TCP Sender Web Service Sender Additional connectors are made available as extensions: Email Reader Serial Connector NextGen Results CDR Connector FHIR Connector Interoperability Connector Suite Parent topic: Connector Components

Channel Writer

The Channel Writer is a connector that simply dispatches messages to other internal channels. This can be useful if you split your message workflow into multiple channels, where one sends to another. If no target channel is specified, the connector acts as a "sink" where no message dispatching is done. Note that a channel does not need to use a Channel Reader source for a Channel Writer to be able to send messages to it. The connector also has options to inject source map variables into the downstream message of the target channel. Supported property groups: Destination Settings Item Name Default Value Description A Channel Id <None> The unique ID of the target channel to send messages to. This may be a hard-coded ID, or may be a Velocity Variable Replacement. Use the drop-down menu to the right to quickly select a particular channel. If <None> is selected, the destination will act as a "sink" where messages are not dispatched anywhere. B Message Metadata The map variables entered here

JMS Listener

This source connector connects to an external JMS provider and reads messages from a queue or topic. It supports both JNDI and specifying a specific connection factory, as well as fine-tuned queries through a configurable selector. Once this connector is started, it will attempt to keep a persistent open connection to the JMS provider. If for any reason the connection is dropped, the connector will automatically reconnect without any intervention needed. The properties view also includes a mechanism to save configuration templates for common provider types, so that creating a new JMS Listener is as quick and easy as possible. Note: Depending on the JMS connection provider you are using, you may need to include some external libraries (JARs) as a Library Resource and include them using the Set Dependencies dialog on the Channel Summary tab. For example, to use connection templates included for ActiveMQ and JBoss, you should download the libraries from their official site in order to use

HTTP Listener

This source connector acts as an HTTP server, listening for requests from one or more remote clients. The messages sent to the channel can be the raw payload, or an XML document allowing multipart payloads to be parsed in a consistent and easy-to-use way. The HTTP payload can be either Base64 encoded or converted using a charset, depending on the Content-Type. Responses that go back to each client can be fully configured, including custom response headers. Finally, static resources or directories can be automatically hosted, to allow the connector to act as a simple web server that serves specific content. Additional options are available with the SSL Manager extension. Supported property groups: Listener Settings Source Settings HTTP Authentication Settings Item Name Default Value Description A Base Context Path The context path for the HTTP Listener URL. Note: If this is specified, any requests made at this base context path must have a trailing slash in the request URI. B Receive Ti
