Some suggestions;

1.    Remove xsi:schemaLocation from the schema document. It's not needed,
and in fact is not allowed, as far as I can remember

2.    Your instance document specifies a namespace URI for all elements (
http://localhost:8080 ) but your schema document has no corresponding
targetNamespace attribute. Add a targetNamespace='http://localhost:8080' to
your schema document

3.    Your schema document contains various QNames that begin with the
prefix 'j' but you do not provide a namespace declaration for such a prefix.
Add a namespace declaration to your schema document that reads
xmlns:j='http://localhost:8080'

If you make these changes your instance document will be schema-valid per
your schema.
