The HL7 Transport (New in Carbon 4.0) allows you to handle Health Level 7 International (HL7) messages. It is available when you install the Axis2 Transport HL7 feature. After you install the HL7 transport, it is configured in <ESB_HOME>/repository/conf/axis2/axis2.xml as follows:
...
6. Set the Java system property "ca.uhn.hl7v2.llp.charset" to control the encoding type of incoming messages.
Setting Application-Acknowledgement
User has to define a property in the sequence to make system to identify the "application-acknowledgement" configuration.
eg: <property name="HL7_APPLICATION_ACK" value="true" scope="axis2"/>

User has to define this property in the InSequence, to make the system, to wait for response from the backend application or to generate the Accept-Acknowledgement messages. |
Configuring the TIMEOUT period for waiting response from backend application
In general, we don't depend on the backend application's response. What we do is, sending back an "Accept-Acknowledgement" message to client. But in some usecases, user wants to depend on the "Application-Acknowledgement". In such cases,the request thread has to wait till the backend application returns the response. We can configure that, TIMEOUT period at transport level.
eg: <parameter name="transport.hl7.TimeOut">1000</parameter>

<transportReceiver name="hl7" class="org.wso2.carbon.business.messaging.hl7.transport.HL7TransportListener"> Please note that Timeout value has to be provided in Milliseconds. |
