Hello,
i'm moving now from geotoolkit to Apache SIS, progressively, by using
Geotk 4.0-M1 which uses some apache SIS modules (0.3-jdk7), and in the
meantime, moving from jdk6 to jdk7.
What i have is a class that extends the DefaultMetadata.
I have a marshaller unit test that works fine. And the main application
of my program works fine to marshall the metadata when i use it directly
from Eclipse.
To use the my tool outside Eclipse, i've built a shaded Jar with Maven
to embedd all dependencies.
But when i try to to run it the main application from command line, i
get an error dealing with JAXB context.
I was previously using similar code with geotk, and it was working properly.
The first error i get deals with the missing annotation
@XmlRootElement(name = "MD_Metadata") for my subclass

After adding the missing annotation, everything still works (tests, main
app in Eclipse)
If i try to run the app with the shaded jar, i get the following error:
/Exception in thread "main" java.lang.Exception: Fail to publish

Do you have any idea what is wrong? (and also why would i need to add
/xmlRootElement/? )
What are the differences between the geotk JAXB xml marshaller and the
Apache SIS one?
I would be very grateful if you could advice how to solve this...
Many thanks in advance
Kind regards
