JAXB on Android (was: Google Summer of Code projects accepted)

In my understanding of [1], [2] and [3], we are allowed to use stax-api
and jaxb-api under CDDL license provided that:
* We do not modify the source code (or at least not in the Apache SIS
project).
* We redistribute only the binaries (e.g. as Maven dependencies), not
the source.
If I'm understanding right, fasterxml is under Apache 2 license, is that
right? If so, then I think there is no objection in trying to use it on
Android if it works.

Understood. Then the initial proposal (fasterxml with JAXB annotations
under CDDL license) would be nice if it works. Otherwise SimpleXML seems
fine to me.

It is needed only at runtime.

Hello Sisinda
Thanks for the report. I think that using original JAXB implementation
under CCDL license is fine, and would probably be the easiest approach
for us. Is the aalto-xml library needed only at runtime, or is it needed
at compile-time too?

Hello Martin,
Sorry for the delay. While I was working on the org.apache.sis.xml package,
I tried jaxb unmarshalling again and I
managed to make it work by additionally including aalto-xml library (Apache
license 2.0) from fasterxml project.
So is it ok to keep the original jaxb implementation in the SIS library as
there are no
conflicts with the licenses?

Yes, here it is https://github.com/dinush/sis
I will commit to a new branch named Android2

Thanks, all the information you provided looks good. I think you have a
GitHub repository for this work, is it right? (sorry if you already
provided the link and I forgot it)

Hello Martin
* It is not a modified version. I included dependencies from maven
repository.
These are the packages included,
1. javax.xml.bind/jaxb-api
2. javax.xml.stream/stax-api
3. javax.activation/activation
4. com.sun.xml.bind/jaxb-core
5. com.sun.xml.bind/jaxb-impl
* I used FasterXML xml object mapper and FasterXML jaxbAnnoationModule
together with javax.xml.bind.annotation classes

Hello Sisinda
Thanks for the update. Just to clarify my understanding:
* In the first case, you tested with JAXB API together with JAXB
Reference Implementation (RI), or was it a modified version of JAXB RI?
* In the second case, you tested with JAXB API (annotations and
adapters) together with FasterXML as an implementation of that API?
In any case, your experiment sound encouraging!

Ok, I have created a simple Android app with 2 JAXB annotated classes. I
was able to marshal those classes with JAXB marshaller. But unmarshalling
generated errors (org.xml.sax.SAXNotRecognizedException). Then I changed to
fasterxml with existing JAXB annotations and it worked for both marshalling
and unmarshalling with similar xml output provided by JAXB. So I will try
to find a solution for the JAXB unmarshalling error, and in case it failed,
I will implement with fasterxml.
