jsf 2 - JSF commandButton - passing POST params to an external site -

I need a link that redirects me to a different site and sends the POST parameter. Something like this:

  & lt; H: form & gt; & Lt; H: command button value = "submit" action = "http://example.com" & gt; & Lt; F: Ultimate name = "user" value = "roxan" & gt; & Lt; / H: CommandButton & gt; & Lt; / H: form & gt;   
 The above code does not work at all.  
 I want to get it in HTML:  
  & lt; Form action = "http://example.com" method = "POST" & gt; & Lt; Input type = "hidden" name = "user" value = "robson" & gt; & Lt; Input type = "submit" value = "submit" & gt; & Lt; / Form & gt;   
 Is this possible?   
 
 
 Vanilla HTML  & lt; Form & gt;  tag, if you are going to send form data to a non-JSF target, then not the JSF tag.  
 The operation is designed to facilitate, so it has no "action" attribute.
