[jacorb-developer] Are there IDL constructs Similar to Java Annotations?

[Rob Ratcliff]

Kujtim (et al),

I thought you might be interested in this thread I started a few years
ago regarding improving the flexibility of the IDL to language mapping
using annotations similar to JAXB and ICE:
https://groups.google.com/d/topic/comp.object.corba/viO06npeT9c/discussion

Based on this discussion it looked like the only mechanism to do this in
IDL was #pragma. Embedding an annotation into a comment could work as
well without having to change the IDL specification similar to XDoclet
(http://xdoclet.sourceforge.net/xdoclet/using.html ).

I think providing a way for developer to create custom mappings from IDL
to their Java or C++ code would make CORBA more attractive to
developers. JAXB is a great example of doing this for Java and
XML-schema-based messaging implementations. (I prototyped a conversion
tool that created IDL from JPA annotated Java code, transformed the
original Java classes into the CORBA classes and vice-a-versa using
Reflection: https://kenai.com/projects/transmogrify  . Ideally an
approach like this could be moved into the JacORB code generator to
remove the need to transform the classes, but an approach like this
could be a way to experiment with mappings in the short term.)

Anybody associated with the OMG heard of any movement to do add custom
mappings to the specification?

Thanks,

Rob

My question is: are there constructs in IDL elements specification like annotations in Java to give an element (operation, attribute, ...) some metadata to process with external tools or JacORB generated modified Java code?
