     final  WebClient webClient  =   new  WebClient();

     //  Get the first page 
     final  HtmlPage page1  =  webClient.getPage( " http://some_url " );

     //  Get the form that we are dealing with and within that form, 
     //  find the submit button and the field that we want to change. 
     final  HtmlForm form  =  page1.getFormByName( " myform " );

     final  HtmlSubmitInput button  =  form.getInputByName( " submitbutton " );
     final  HtmlTextInput textField  =  form.getInputByName( " userid " );

     //  Change the value of the text field 
     textField.setValueAttribute( " root " );

     //  Now submit the form by clicking the button and get back the second page. 
     final  HtmlPage page2  =  button.click();
}
