apogee xfroms and SAX parser questions

Hello, apogee@...!

Sorry my English.

I'm trying build simple OLTP demo application with Apogee XFroms and
Xml-Xindice. Xml instances is stored in Xindice and editing by Apogee
XFroms based on TestSWT document.* files - samples from
org.nuxeo.xforms.ui.tests

Environment:
Eclipse JEE 3.3
JDK 1.6.0_02/1.5.0_12

I'm write code editing document. It works fine without of Xindice
libraries.
//....
            ViewShell view = new ViewShell();
            view.open("");
// ....
public class ViewShell {
   private Shell sShell = null;
   private void createSShell() {/* skipped default code for Shell
creation */}

    private void createXForms(String xmlSource) {
        XInputSource src = new
URLInputSource(this.getClass().getResource("document.xhtml"));
        XFormsProcessor proc = new XFormsProcessor(src);
        if (!xmlSource.equals("")) {
            src = new StringInputSource(xmlSource);
            proc.getForm().getModel().setInstance(src);
        }
        FormViewer viewer = new FormViewer(proc, sShell, true);
    }

    public void open(String xmlSource) {
        createSShell();
        createXForms(xmlSource);
        sShell.pack();
        sShell.open();
    }
}

By adding Xindice libraries I've got errors. Can you help me with it?
Please.
