[HAPI-devel] How to use XML-binding to generate library classes for hapi parser?

[Iouri L. <il...@mo...>]

Good day developers.

Recently I've started playing with hapi framework. I have a question
relating to configuration of messages.

Let' say we have a very common scenario - a user wants his custom segment
ZUSER with some custom datatype MY_DT. I see the only way to do it - make
new Java files. I have to create a new ZUSER.java in  segment package and a
new MY_DT.java in datatype package. Then I have to go to message package and
change message ADT_x.java file in order to make it work with these new
segment and datatype. Job that definitely requires skills of a Java
programmer.

My question relates to ways of descriptive programming. Is there a way in
the current hapi implementations to describe the content of my new segment
and datatype not in .java file but rather in some XML file or in w3 XML
Schema file then run that xml instance through a binding parser which will
generate classes ZUSER.class and MY_DT.class which can be used directly by
Pipe parser? Something in line with JAXB - XML binding.  If there is a way,
then how to do it, if there's none - any idea how to make it  happen?
