Can't read kml #26

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I jsut downloaded the  jak from "http://labs.micromata.de/display/jak/Download";
But i found, i can't read kml, even created by jak.
Here is my piece of code.
public static void main(String[] args) {
        Kml kml = Kml.unmarshal("D:/doc/admod/kml/test.kml");
        Document document = (Document) kml.getFeature();
        JAXBContext j;
        kml.marshal();
    }
And the kml file just created by jak
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<kml xmlns="http://www.opengis.net/kml/2.2" 
xmlns:gx="http://www.google.com/kml/ext/2.2" 
xmlns:atom="http://www.w3.org/2005/Atom" 
xmlns:xal="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0">
    <Document>
        <name>JAK Example1</name>
        <open>1</open>
        <Folder>
            <name>Continents with Earth's surface</name>
            <open>1</open>
        </Folder>
    </Document>
</kml>
When i try to read the file. I got these exceptions.

It's all my fault.
The correct code should be this:
Kml kml = Kml.unmarshal(new 
FileInputStream("E:/software/开发相关/java/javaApiForKml/exampledata/worldBo
rders.kml"));
        Document document = (Document) kml.getFeature();
