I'm looking over some of what you said. I'm trying to meet a deadline, so right now, I'd just like to get the XSD working with the mapping. However, I do plan on looking into the XML code generator next week.
I've changed a few things around, but I'm still having issues. For some reason, http://www.castor.org/how-to-enable-xml-validation.html just isn't clicking. *castor.xml*: <?xml version="1.0"?> <!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN" "http://castor.org/mapping.dtd";> <mapping xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="db-config-1.0.xsd"> *db-config-1.0.xsd*: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";> *db-config-sample.xml*: <?xml version="1.0" encoding="UTF-8"?> <dataSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="db-config-1.0.xsd"> This is the error I get when I try to unmarshal: java.lang.RuntimeException: org.exolab.castor.mapping.MappingException: Nested error: org.exolab.castor.xml.MarshalException: Attribute "xmlns:xsi" must be declared for element type "mapping".{File: [not available]; line: 6; column: 52} Can you tell me what I'm doing wrong here?
