[jibx-users] HashMap not working during jibxbind

I'm trying to map a class that has only one, static, element, which is a HashMap from String to another class.

I have the following binding file:

</binding>

Here is the core part of the HelpServices class:

public class HelpServices {

private static HashMap help = new HashMap();
}

The mapped objects are HelpReferences, and the keys are Strings. Here is the core part of the HelpReference class:

public class HelpReference {

private String URL;
private int mapId;
}

When jibxbind runs, I'm getting the following error message:

java.lang.IllegalStateException: Internal error: Expected java.util.HashMap on stack, found com.quest.wcf.core.services.HelpServices
full stack:
0: com.quest.wcf.core.services.HelpServices
1: com.quest.wcf.core.services.HelpServices

Any bright ideas on what I'm doing wrong? Does it have anything to do with the fact that the HashMap element is static? It's really only the HashMap element that I want to marshall / unmarshall, since the class isn't even intended to have any instances.

WAIT ... I'm trying something different. Now my binding is as follows, and jibxbind works OK:

</binding>

But when I run the following code:

private static HashMap help = new HashMap();

static {
    try {
        IBindingFactory bfact = BindingDirectory.getFactory(HashMap.class);
        IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(4);
            mctx.marshalDocument(help, "UTF-8", null,
                new FileOutputStream("HelpReferences.xml"));

    }
    catch (JiBXException je) {
        System.out.println("JiBXException marshalling HelpReferences: " +
                je.getMessage());
    }
    catch (FileNotFoundException fnfe) {
        System.out.println("FileNotFoundException marshalling HelpReferences: " +
                fnfe.getMessage());
    }
}

what happens is the JiBXException is thrown, with the message:

Unable to access binding information for class java.util.HashMap
Make sure the binding has been compiled

Any bright ideas about that? Which approach is more correct?

Thanks.
