A convenience method for binding applications to an ApplicationRouter Information about bindings is read from a file at a specified URL. Each line in the file should have the following format (entries TAB delimited):

message_type trigger_event processing_id version_id app_class

Note that the first four fields can be the wildcard "*", which means any.

For example, if you write an Application called org.yourorganiztion.ADTProcessor that processes several types of ADT messages, and another called org.yourorganization.ResultProcessor that processes result messages, you might have a file that looks like this:

ADT * * * org.yourorganization.ADTProcessor
ORU R01 * * org.yourorganization.ResultProcessor

Each class listed in this file must implement either ca.uhn.hl7v2.app.Application or ca.uhn.hl7v2.protocol.ReceivingApplication, and must have a zero-argument constructor.

Parameters:

theRouter - the ApplicationRouter on which to make the binding

theSource - a URL pointing to the bindings file

Throws:

java.io.IOException

HL7Exception

java.lang.ClassNotFoundException

java.lang.InstantiationException

java.lang.IllegalAccessException
