[Exist-open] RE: Problem with lost namespace in embedded eXist

[KevinBenson <km...@ms...>]

I was wondering if anybody had any ideas on this one.  I did investigate a
little more there is nothing to do with missing a jar.  Just seems to be the
query mechanism in a embedded eXist that is causing that namespace to get
lost.  If it helps my queries are always getting at the vor:Resource for
example normally I declare a bunch of namespaces and do a (for $x in
vor:Resource where vr:identifier='ivo://astrogrid.mssl/fits_trace')  In
general it happens on all the queries I do.

Also I tend to do a getMembersAsResource() method, so I do need to verify by
going into the actual ResourceSet, but I am fairly certain the same thing
will happen.

cheers,
Kevin

Subject: Problem with lost namespace in embedded eXist


I cannot figure out if there is a jar I am missing or something else.  But
in general i store a file very similiar to the one below.  Using XMLdb api
querying in embedded mode.  I tend to lose the namespace of the <table>
element hence the VODataService namespace (also <coverage> element).  The
storage seems to be correct and I can query on the table(and sub elements)
with the VODataService namespace.  But when I receive the xml back it seems
to be gone.

I changed things around to point to a external eXist via xmlrpc and
everything seems to be correct there.  I thought at first it might be a jar
file missing, I noticed a few of the original eXist/lib/endorsed missing
from my web-inf/lib directory, but I have now fixed that and still same
result.

Any ideas? Is there something in the conf.xml that would cause this?  Thank
you for your answers.


Sample XML below, table element essentially gets the vr(VOResource)
namespace on the query in embedded mode (because it has no namespace given
back) it should be the vs namespace (VODataService).  (I believe it is
happening on the coverage element as well, but right now been focused on the
table element.)
