        HTTPServiceDescriptor descriptor = new HTTPServiceDescriptor();
        descriptor.setURL("https://chemicalize.com/tomcat-files/datapage.jsp");
    
        descriptor.addArgument(ServiceArgument.createArgument("mol", ""));
        descriptor.addArgument(ServiceArgument.createArgument("special", ""));
        descriptor.addArgument(ServiceArgument.createArgument("pka_width", 0));
     
        Object result = null;
        try {
            result = descriptor.getServiceHandler().callService(descriptor, "c1ccnccc1", "pka", 300);
        } catch (ServiceException e) {
           System.err.println("Service call failed.");
        }
        System.out.println("Synchronized call returned: " + String.valueOf(result));
     
    
        descriptor.getServiceHandler().callService(descriptor, new AsyncCallback<String>() {
     
            @Override
            public void onSuccess(String result) {
                System.out.println("Aynchronous call returned: " + result);
            }
     
            @Override
