AsyncCallback

Hi everyone!
Using rpc I call the method which must return Long type.

    private final ServerManagementAsync serverManagementSvc = GWT.create(ServerManagement.class);

   public ContentPanel createChart(final String customerId){


       final Long queueSize;
       AsyncCallback<Long> ac = new AsyncCallback<Long>() {
           @Override
           public void onFailure(Throwable throwable) {
               //To change body of implemented methods use File | Settings | File Templates.
           }


           @Override
           public void onSuccess(Long aLong) {
               //To change body of implemented methods use File | Settings | File Templates.
           }
       };
       
       //here I need to add this value to queueSize
       serverManagementSvc.getMessageQueueSize(customerId, ac);

but is sais that this method returns the void type
here is the method itself

public Long getMessageQueueSize(final String customerId) throws Exception{        RuntimeStats rs = mi.getStats(customerId);
        return rs.getQueueSize();
    }

here is it is in interface

Long getMessageQueueSize(String customerId) throws Exception;

Oh, the solution differs from what I thought. But I've found it
