Expecting no namespace, but the schema document has a target namespace 2003-01-13 - By sandygao@(protected)
Xerces defers the loading of schemas. That is, a schema is loaded only when
something from its target namespace is required. In your case, your xsd
file will only be read if the namespace "
http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2
" is referenced. I don't think it's referenced, because there is even no
namespace declaration for that namespace.
I also planned to reply your other mail. Here it goes:

Schema locations are specified using one of the xsi schema location
attributes, like what you did for the MM7 schema. A namespace declaration
like the above doesn't mean the parser needs to retrieve a schema for that
namespace, not to mention that the parser doesn't know where to retrieve
such schema.
To fix it, add an xsi:schemaLocation attribute for this namespace. So the
result would something like:
xsi:schemaLocation="mm7_namespace mm7.xsd soap_namespace soap.xsd"
This is also the reason why you are seeing the cvc-elt error. You didn't
provide a location for the soap namespace, so Xerces couldn't find a
declaration for your root element.

If there is no DTD in your instance, then Xerces only does schema
validation. But if you do have a DTD, Xerces validates the instance against
both kinds of grammars. This is not correct as per JAXP. We'll fix it so
that when schemaLanguage==xmlschema, no DTD validation is performed.

Sandy,
Thanks for the reply, but ....
I just changed the my SOAP envelope so that the root document is now, as
you have suggested, like this:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:schemaLocation=
"
http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2
http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-2.xsd
">
But the problem now is it does not even seem to try or perform a schema
validation.
Running a sniffer, no attempt has been made by the parser to retrieve
the schema document from www.3gpp.org.
But I do still get the following error, also reported on my original post:
Error: URI=null Line=8: cvc-elt.1: Cannot find the declaration of
element 'SOAP-ENV:Envelope'.
The only way I could achieve some level of schema validation is by using
xsi: noNamespaceSchemaLocation, as mentioned in here:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPDOM9.html
I would prefer declaring the schemas in the XML document itself ...
rather than assigning them by code.
Any ideas?
Thanks
