Hello Vijay,
You can wirte the following code to get the logged in user's ID
try {
          IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
          IUser sapUser = wdClientUser.getSAPUser();
          IUserAccount[] acct = sapUser.getUserAccounts();
          String str = acct[0].getDisplayName();
          wdComponentAPI.getMessageManager().reportSuccess("user "+ str);
     } catch (WDUMException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
     } catch (UMException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
You need security api for using it make sure that is present.
Thanks,
Hope this will help
