Good morning!

Is there already a ready-to-use table/mapping I oversee? I want to know,
which
xsd documents are cached inside this jar. Other I'll cache in the
application...

Regards,
Christian

I'm not quite sure what you are asking. A few "meta schemas" are cached in
xsd.resourses.jar, i.e., the ones that appear in the org.eclipse.xsd/cache
directory. If there are schemas out on the web or elsewhere for which you
would like to provide a local copy, you can use a URIConverter's URI Map,
either the global one or the one in a particular resource set, to map a
logical namespace to a physical cached location (or to map a resolved
schemaLocation to a local cached location).

Yepp. I just wondered, whether there is a listing of those "few" schemata
which is also supplied within that jar.

My goal is to present the user a dialog where he/she sees all used/loaded/
included/... schemas. An additional info for each schema in that list is
if it is cached locally or not. And if not, the dialogs offers a download
button. (...) The download button should be disabled, if the schema
namespace
is already cached.

Christian

Dumping all Map.Entry items of different maps results in the following:

-----------------------------
dump(URIConverter.URI_MAP);
-----------------------------
Map is empty.

-----------------------------
dump(XSDSchemaImpl.getGlobalResourceSet().getURIConverter(). getURIMap());
-----------------------------
http://www.w3.org/2001/xml.xsd -> jar:file:/D:/Workspace/ \
schemaprof/ext/xsd_2.0.0_20040127_1738SL.resources.jar! \
/org/eclipse/xsd/cache/www.w3.org/2001/xml.xsd

-----------------------------
dump(XSDSchemaImpl.createResourceSet().getURIConverter().get URIMap());
-----------------------------
Map is empty.

-----------------------------
dump(new ResourceSetImpl().getURIConverter().getURIMap());
-----------------------------
Map is empty.


So the only set, which has ONE mapping installed is the global one
managed by XSDSchemaImpl. Where are the entries for other "often
-used" schema files that are also inside the resource.jar? Are they
mapped "magically" and are never put into an accessable map?

Next question is, which ResourceSet should be used to "load" schema
in general? The global one? A fresh instance provided by "XSDSchemaImpl.
XSDSchemaImpl.createResourceSet()" or via hand with "new
ResourceSetImpl()".
Where is the difference between the last two ways?

Regards,
Christian

Christian,

The global XSD resource set should be used to load schemas only by the XSD
implementation. The schema for schemas is loaded magically from the "jar"ed
location. Its import of the XML namespace schema uses an absolute
schemaLocation so that one mapping is added local to the global XSD resource set
to redirect that back into the "jar"ed location.

You should avoid using any of the Impl classes directly so you should just new a
ResourceSetImpl and add manually any registrations needed to it.

-----------------------------

So the only set, which has ONE mapping installed is the global one
managed by XSDSchemaImpl. Where are the entries for other "often

The global XSD resource set should be used to load schemas only by the XSD
implementation. The schema for schemas is loaded magically from the "jar"ed
location. Its import of the XML namespace schema uses an absolute
schemaLocation so that one mapping is added local to the global XSD resource set
to redirect that back into the "jar"ed location.

ResourceSetImpl and add manually any registrations needed to it.
