HL7 is being replaced by X12. You may want to move to the next standard.
Just to let you know there is an open source project that will be using
JBoss as its default App Server that supports HL7,X12,Delimited,Fixed,
SQL,Corba,DCOM,XML etc. This interface engine will transform to and from
and is about to be announced in the next couple of months.
It uses JMX,JMS for most of its work and is fully configurable with the hope
of no scripting.
