Unable to open or read KML files

[GoogleCodeExporter]

I just tried setting up a little Java application to read and write KML files 
with this library. I am using the latest Eclipse version on Win XP x32. I 
started with a very simple class looking like this:

import de.micromata.opengis.kml.v_2_2_0.*;

public class Main {
    public static void main(String[] args) {
        Kml kml = new Kml();
        kml = Kml.unmarshal(("borabora.kml"));
        Document document = (Document) kml.getFeature();
    }
}

In the proect properties, I added references to:
- jaxb-impl-2.1.9-sources.jar
- JavaAPIforKml-sources.jar

Eclipse does not show any errors or warnings before trying to compile, but when 
I try to compile I receive the following exceptions:

javax.xml.bind.JAXBException
 - with linked exception:

    ... 5 more

I have already opened jaxb-impl-2.1.9-sources.jar with WinRar and I found the 
class com.sun.xml.bind.v2.ContextFactory where it's supposed to be. (Actually 
no class seems to be missing.)
I did not try to read attributes from the file, because I was not yet able to 
open any file at all.

What am I doing wrong?

It seems to be working now. Trying to include the sources seemed to be the 
problem.
Added the compiled libraries to the project now (these containing the .class 
files) and can now read and write KML files.

Regards.
