My java code to validate xsd against xml is as follows : -

SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = factory.newSchema(new File("/tmp/checkxsd.xsd"));
    Validator validator = schema.newValidator();
    validator.validate(new StreamSource(new File("/home/my-pc/MyXMLFile.xml"))

Any help is greatly appreciated. I am stuck with this.

Answer 1

The message you are seeing almost invariably means the validator is not loading the schema; in turn, this is almost invariably because it can't find it; this in turn is almost always because of some error in specifying the locations of the schema documents to be processed.

Once the over-long lines in your example are broken and the start-tag for the outermost element can be read conveniently without scrolling right and left, one source of your problem (not necessarily the only one) seems clear. What do you believe is the meaning of the attribute-value specification

xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/
                    http://schemas.xmlsoap.org/soap/envelope/ 
                    /tmp/checkxsd.xsd"> 

(At this point, I expect you either have a head-slap experience or raise your eyebrows in puzzlement. If the latter, I suggest you consult some documentation.)
