HTTPClient e AJAX

Fala galera,

Tenho um probleminha.
Estou fazendo uma aplicação que loga em um sistema, clica em um link e após isso vai para uma página que abre uns radio buttons, entretanto, esses radio button aparecem conforme a disponibilidade do sistema, se existe um item disponivel, aparece.
Essa dinamica creio que seja feita em AJAX, eu preciso marcar o primeiro dos radio button.
A linha do código fonte HTML que aparece, quando eu solicito o código fonte, correspondente a chamada do AJAX é:

1. &lt;input type="hidden" id="formPrincipal:idExecutaRefresh" name="formPrincipal:idExecutaRefresh" value="N"&gt;&lt;input type="hidden" name="oracle.adf.faces.FORM" value="formPrincipal"&gt;&lt;span id="_formPrincipal_Postscript"&gt;&lt;input type="hidden" name="oracle.adf.faces.STATE_TOKEN" value="11"&gt;&lt;script&gt;function _formPrincipalValidator(){return true;}var formPrincipal_SF={};&lt;/script&gt;&lt;/span&gt;&lt;script&gt;_submitFormCheck();&lt;/script&gt;&lt;/form&gt;&lt;/body&gt;&lt;!-- Created by Oracle ADF Faces (ADF Faces API - 10_1_3_3_0/ADF Faces Implementation - 10_1_3_3_0), skin:oracle.desktop (oracle) --&gt;

parece que tem um campo hidden, acessando um BD Oracle.

Preciso fazer a aplicação marcar um radio button que só aparece quando está disponivel, em AJAX, mas não sei como, alguém pode ajudar?

Obrigado desde já.

Acabei de descobrir um problema, pela minha aplicação o código do ajax simplesmente não carrega.
Esse é o trecho de código HTML da pagina no qual o navegador me mostra e minha aplicação não.

&lt;span id="formPrincipal:idPainelCarregamento"&gt;<img    >&lt;table cellpadding="0" cellspacing="0" border="0" width="100%" summary=""&gt;&lt;tr&gt;&lt;td style="background-image:url(/transportador/adf/images/cache/ccclts.gif);background-repeat:no-repeat" width="11" height="11"&gt;&lt;div style="margin-top:11px;padding-left:11px"&gt;&lt;/div&gt;&lt;/td&gt;&lt;td width="100%" class="x8x x5z" style="padding-right:10px"&gt;&lt;table cellpadding="0" cellspacing="0" border="0" width="100%" summary=""&gt;&lt;tr&gt;&lt;td width="100%" valign="bottom"&gt;&lt;table cellpadding="0" cellspacing="0" border="0" width="100%" summary=""&gt;&lt;tr&gt;&lt;td&gt;&lt;h1 class="x20 AFHeaderAlias"&gt;Par&acirc;metros&lt;/h1&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td width="100%" height="1" class="x3o"&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="BGAccentLight" height="5" colspan="3"&gt;&lt;div style="margin-top:5px"&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td class="x8x x5q"&gt;<img    >&lt;/td&gt;&lt;td width="100%" class="x8x x5t" style="padding:0px 10px 5px 0px"&gt;&lt;div&gt;&lt;table cellpadding="0" cellspacing="0" border="0" summary=""&gt;&lt;tr&gt;&lt;td&gt;&lt;div&gt;Transportadora&lt;div&gt;&lt;/div&gt;&lt;table id="formPrincipal:idTransportadora__xc_" cellpadding="0" cellspacing="0" border="0" summary=""&gt;&lt;tr&gt;&lt;td class="xe" nowrap&gt;&lt;/td&gt;&lt;td&gt;&lt;/td&gt;&lt;td valign="top" nowrap&gt;&lt;script&gt;var _pprUpdateMode=false;function _adfspu(f,v,e,s,o){_pprUpdateMode=true;if(!o)o=new Object();o.event=(e)?e:'update';if(s)o.source=s;_submitPartialChange(f,v,o);}&lt;/script&gt;&lt;select id="formPrincipal:idTransportadora" name="formPrincipal:idTransportadora" onchange="_adfspu('formPrincipal',1,'formPrincipal:idTransportadora','formPrincipal:idTransportadora');return true;" class="x6" style="width:370px"&gt;&lt;option value="0" selected&gt;M.
