Components from namespace 'null '

Components from namespace 'null '

I am trying to validate the my xml with external schema validation.

My setting are :

parser.setFeature("http://apache.org/xml/features/validation/schema", true);

parser.setProperty("http://apache.org/xml/properties/schema/external-schemaL
ocation","IAR http://localhost:7001/IAR/Transaction.xsd");

My Schema is defined as :

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' targetNamespace="IAR"
elementFormDefault="qualified">
<xs:element name="Transaction">
 <xs:annotation>.

.

.

.

</xs:schema>

When I run I get this error message :

[Error] :1:86: src-resolve.4: Components from namespace 'null' are not
referenceable from schema document
'http://localhost:7001/IAR/Transaction.xsd'.

[Error] :1:86: src-resolve.4: Components from namespace 'null' are not

I get similar error when I run the sample Xerces files (personal.xml and
personal.xsd) as input to my program.



What is that I am doing wrong?



Thanks
