Thank you Bhakti and Kenny. That worked perfectly. Below is the final code.
Josh
***begin code***
// unmarshall objects
InputStream schemaStream = Main.class.getResourceAsStream("/outlet.xsd");
InputStream xmlStream = Main.class.getResourceAsStream("/xmloutlet.xml");
List<OutletIF> currentConfiguration = null;
Object unmarshalledObject = null;
try {
JAXBContext context = JAXBContext.newInstance(
ic.plugin.pulizzi.outletcontrol.outlet.OutletInfo.class);
final SchemaFactory sf = SchemaFactory
.newInstance("
http://www.w3.org/2001/XMLSchema");
final Schema schema = sf.newSchema(new StreamSource(schemaStream));
Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.setSchema(schema);
unmarshalledObject = unmarshaller.unmarshal(xmlStream);
} catch (Exception ex) {
System.out.println ("Exception: " + ex);
ex.printStackTrace();
System.exit(-1);
}
// check if demarshalled object was null
if (unmarshalledObject == null) {
// null result
System.out.println ("Demarshalling failure. Object was null.");
System.exit(-1);
}
// all good, print out demarshalled objects
final OutletInfo outletInfo = (OutletInfo)unmarshalledObject;
currentConfiguration = outletInfo.getOutlets();
for (OutletIF outlet : currentConfiguration) {
System.out.println(outlet);
}
***end code***
