Dear Kishore,
To get the Employee ID you have to create a Adaptive RFC Model (call BAPI) which will return you the employee pernr, for this
1. Create a model using  : BAPI_EMPLOYEE_GETDATA
2. Get User ID using the code
public java.lang.String getUserID( )
    //@@begin getUserID()
     String userID = new String();
          try
                // getting Logged in userid
               IWDClientUser myUser = WDClientUser.getCurrentUser();
               userID = myUser.toString().substring(19).trim();
               StringTokenizer filterdUID = new StringTokenizer(userID,")");
               userID = filterdUID.nextToken();
          catch (WDUMException e)
               e.printStackTrace();
               return userID;
    //@@end
3. Execute the BAPI
public java.lang.String getEmployeeID( java.lang.String userID )
    //@@begin getEmployeeID()
     String employeeID = new String();
          Bapi_Employee_Getdata_Input employeeData = new Bapi_Employee_Getdata_Input();
          Bapi_Employee_Getdata_Output outData = new Bapi_Employee_Getdata_Output();
          Bapip0105B comm = new Bapip0105B();
          com.sap.aii.proxy.framework.core.AbstractList list = new Bapip0105B.Bapip0105B_List();
          list.add(comm);
          employeeData.setUserid(userID);
          Calendar cal = Calendar.getInstance(Locale.UK);
          Date date = new Date(cal.getTimeInMillis());
          employeeData.setDate(date);
          employeeData.setAuthority_Check("");
          employeeData.setCommunication(list);
          outData.addCommunication(comm);
          wdContext.nodeBapi_Employee_Getdata_Input().bind(employeeData);
          wdContext.nodeOutput_BAPI().bind(outData);
        try
               wdContext.nodeBapi_Employee_Getdata_Input().currentBapi_Employee_Getdata_InputElement().modelObject().execute();
               wdContext.nodeOutput_BAPI().invalidate();
        catch (WDDynamicRFCExecuteException e) {printMsg("Failed to Obtain Employee Data");
             e.printStackTrace();
        employeeID = wdContext.nodeBapi_Employee_Getdata_Input().nodeOutput_BAPI().nodeOrg_Assignment().currentOrg_AssignmentElement().getPerno();
        return employeeID;
    //@@end
Hope it Helps!!
Warm Regards
