небольшой совет о том, как войти в EPES

В данный момент я работаю над фирменным EPES и хотел бы немного информации;

для подписи у меня есть SignerTestBase.java :

public class SignerTestBase extends SignatureServicesTestBase

{

static protected KeyingDataProvider keyingProviderMy;
static protected KeyingDataProvider keyingProviderNist;

static
{
    try
    {
        keyingProviderMy = createFileSystemKeyingDataProvider("pkcs12", "my/LG.pfx", "mykeypass", true);
        keyingProviderNist = createFileSystemKeyingDataProvider("pkcs12", "csrc.nist/test4.p12", "password", false);
    } catch (KeyStoreException e)
    {
        throw new NullPointerException("SignerTestBase init failed: " + e.getMessage());
    }
}
 public static Document getTestDocument() throws Exception
    {
        //return getDocument("document.xml");

        //==that I changed=====================================================================
        **return getDocument("b.xml");**


}

а также :

@Test
public void testSignEPES() throws Exception
{
    System.out.println("signEPES");

    Document doc = getTestDocument();

    Element elemToSign = doc.getDocumentElement();

    SignerEPES signer = (SignerEPES)new XadesEpesSigningProfile(keyingProviderMy, policyInfoProvider).newSigner();
    new Enveloped(signer).sign(elemToSign);

    **outputDocument(doc, "document.signed.epes.xml");**
}

В основном :

System.out.println("============================================================================");          
        System.out.println("XADESTEST : EPES SIGNATURE");
        System.out.println("============================================================================"); 
        System.out.println();

        SignerEPESTest signerEPESTest = new SignerEPESTest();
        System.out.println("signerEPESTest : " + signerEPESTest.toString());


        /**
         *  ==== NOT OK =====
         */

        **signerEPESTest.testSignEPES();**

И в моей консоли, когда я запускаю:

============================================================================
XADESTEST : EPES SIGNATURE
============================================================================

signerEPESTest : xadestest.SignerEPESTest@1c63e8c
signEPES

Please during I am searching, can anybody help me?
