Hi Tony, You can actually add a custom segment to messages at runtime fairly easily, there is a method called "addCustomSegment(String name)" on the Group class, which is the superclass of Message. Using that, you could add a custom segment fairly easily, and I'm fairly sure (though not positive) that this method existed in the 0.4 release.
The one caviat is that this method adds the segment to the end of the group or message, so you don't have much control over where the segment ends up. The upcoming 1.0 release actually improves this functionality quite a bit, allowing you to choose where in the message a custom segment added at runtime ends up. In addition, very shortly it will be possible to generate custom message structures or segments using the Message Workbench Tool and have HAPI generate custom message classes (this is in CVS already, but documentation isn't yet written. If anyone wants to know more, I'm happy to explain further). If I may ask, why is upgrading the library a lot of coding? Definitely one of our design goals is that new versions should be backwards compatible, so I'm wondering if there's something that needs fixing. The one thing that I can think of that broks backwards compatibiity between 0.4 and 0.5 was that 0.4 had incorrect segment group names for HL7 2.4 and 2.5 message types. Is that the source of your issue? I'm thinking it might be possible to produce structures jars for the newest version of HAPI that used the old structures names if that was it..
