Java: Connecting to Quality Center using qcutils4j.jar

Question

I have developed a runner module for my automation framework which will allow testers author and execute the tests using Eclipse IDE.

Now I am looking to add a module to connect to QC and upload my tests to the respective test plan. For this I am using qcutils.jar.

My Code:

public static void QCConnect()
{
    File fUser = new File("lib");
    File fNat = new File(fUser, "jacob-1.18-x64.dll");
    // Set java library path at runtime

    String javaPath = System.getProperty("java.library.path");
    javaPath = javaPath+";"+fUser.getAbsolutePath()+";";
    System.setProperty("java.library.path", javaPath);
    String javaPath1 = System.getProperty("java.library.path");

   //       Load dll

    System.load(fUser.getAbsolutePath()+"\\jacob-1.18-x64.dll");


    IQcConnection conn = QcConnectionFactory.createConnection("https://<myqc>/qcbin");
    conn.connect("user", "pass", "domain", "project");
    TestClient tc = conn.getTestClient();

    Test t = new Test();
    t.setTestFolder(TestFolder.ROOT_FOLDER + "\\Demo");
    t.setDescription("This is a QcTools4j Test");

    t.setStatus("Design");
    t.setName("myTest");
    tc.saveTest(t)
   }

Encountered Exception:

 org.qctools4j.utils.DllLoader loadLibrary
 SEVERE: DLL not found in the class path!
 Exception in thread "main" org.qctools4j.exception.QcException: Can't get  object clsid from progid

I am a looking for a solution on handling QC using java, I do not mind using any other java package.

Thanks in Advance!
