Re: [Help:] DWR integrates with jsf(myfaces) failed.

You already asked this question on the list. No you are spamming the
list. "can't be showed" is not a good enough description to tell us what
you are doing wrong.

Have you actually looked at the HTML produced from the jsp (the id of the HTML elements)? Have you tried this from the DWR test page
(http://yourhost:yourport/yourapp/dwr/index.html)? Have you tried using firebug to look at the data being returned? What gets alerted if you uncomment //alert(data);? Try using alert(dwr.util.toDescriptiveString(data, 3)) instead.

The setValue function uses the id of the HTML element so if there is no element with an id of "formLogin:output" it will not populate the element (which is why I told you to look at the generated HTML and make sure this id exists).
dwr.util.setValue("formLogin:output", data);
