The HL7 Transport (New in version 4.0) is available as an installable feature in WSO2 ESB. The user can plug it in if case of necessity and create a Proxy Service with this transport.
Follow the instructions below to create a Proxy Service with HL7 transport.
1. Sign in. Enter your user name and password to log on to the ESB Management Console.
2. Plug in the HL7 transport. See Installing HL7 Transport.
3. Create a Proxy service. See Adding a Proxy Service.
This Proxy will receive HL7-client connections and send them further to HL7-server. It will also receive XML-messages with HTTP/HTTPS, and, transforming in HL7, send them further. On the way back, messages will be transformed into XML.
Note
Add the following parameter to the proxy service:
<parameter name="transport.hl7.Port">9292</parameter>
Otherwise the Proxy will be considered as "faulty" one and the HL7 transport will be switched off.
Note
As an endpoint use the Address Endpoint with the URL such as hl7://localhost:9988. This URL consists of the host and port of HL7-server. For example, localhost:9988
