Michael,
In the attached java file, it resolves all the dependent schemas but while
validation it fails. If I move any dependent schmemas, it clearly throws error
but I do not know why validation fails ?
java SchemaReader Company.xsd Company.xml throws following error
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of
element 'Company'.
What should I do to get working ?
Regards
Ajay
