Betreff: Re: Custom HL7 Handlers: How are they recognized by OpenMRS

Hi Martin,

There are two HL7 handlers defined in OpenMRS core here: \
https://github.com/openmrs/openmrs-core/blob/master/api/src/main/resources/applicationContext-service.xml#L368


What that example module code does is append more handlers to this list.

(I fixed the link in the wiki page you reference to point to the correct module code \
in github. Though it's still old-school pre-maven code.)

we need to support some other HL7 message types, so we want to implement some custom \
handlers.

According to this page: https://wiki.openmrs.org/display/docs/Custom+HL7+Handlers I \
assume that OpenMRS reads the message type from the MSH segment and then looks up \
which handler to call.

But in the bean xml code

<bean factory-method="getInstance">
  <property name="HL7Handlers">
    <map>
      <entry key="ADR_A19"><bean/></entry>
      <entry key="XXX_YYY"><bean/></entry>
    </map>
  </property>
</bean>

there is no map from the type, e.g. ADT_A04, to the intended handler class.

My question for now is how does OpenMRS know which handler should be called when \
reading a message from the hl7_in_queue?


Any explanation is appreciated.

Thanks for your answers.

Kind Regards,

Martin Wettig
