Receiving Custom XML Messages via HL7

Purpose

This application demonstrates how to configure WSO2 Integrator: SI Tooling to receive Hl7 events in XML format to the hl7Stream via MLLP protocol and log the events in xmlStream to the output console.

Prerequisites

  1. Install the HAPI testpanel
  2. Save this sample. If there is no syntax error, the following message is shown on the console:
    • Siddhi App ReceiveHl7InXmlFormat successfully deployed.

Executing the Sample

  1. Start the Siddhi application by clicking on 'Run'.
  2. If the Siddhi application starts successfully, the following messages will be shown on the console.
    • Starting SimpleServer running on port 4000
    • ReceiveHl7InXmlFormat.siddhi - Started Successfully!

Testing the Sample

  1. In the HAPI testpanel create a sending connection with the port that is provided in the Siddhi app.
  2. Send the following message from the HAPI testpanel. MSH|^~\&|sendingSystemA|senderFacilityA|receivingSystemB|receivingFacilityB|20080925161613||ADT^A01|589888ADT30502184808|P|2.3

Viewing the Results

See the output.

The following message will be shown on the console if you publish events.
