Creating an HL7 Proxy Service

After you install the HL7 transport, you can create a proxy service that uses this transport to connect to an HL7 server. This proxy service will receive HL7-client connections and send them to the HL7 server. It can also receive XML messages over HTTP/HTTPS and transform them into HL7 before sending them to the server, and it will transform the HL7 responses back into XML.

To create the HL7 proxy service:

1. In the Management Console, create a custom proxy service (see Adding a Proxy Service).

2. In the transports list, specify https, http, and hl7.

3. Create an Address Endpoint with the URL of the HL7 server host and port, such as: hl7://localhost:9988

4. Add the following parameter to the proxy service (required to enable the transport):
   <parameter name="transport.hl7.Port">9292</parameter>

For example:

<proxy xmlns="http://ws.apache.org/ns/synapse" name="hl7testproxy" transports="https,http,hl7" statistics="disable" trace="disable" startOnLoad="true">
       <target>
          <inSequence>
             <log level="full" />
          </inSequence>
          <outSequence>
             <log level="full" />
             <send />
          </outSequence>
          <endpoint name="endpoint_urn_uuid_9CB8D06C91A1E996796270828144799-1418795938">
             <address uri="hl7://localhost:9988" />
          </endpoint>
       </target>
       <parameter name="transport.hl7.Port">9292</parameter>
    </proxy>
