Login From Other Site form

[minduba_br]

Hi, I´m new on Spring. I made a webapp with java/tomcat/spring to a client. Now, the client wants to put a form on his webpage, to login to my app. But the app it´s located on my server, and his webpage it´s on his server. I tried a Ajax request based on url of acgei security.

function AjaxPost()
{
var xmlhttp = objectXML(); //Creates XML Request Object
var data = "j_username=login&j_password=pass&acegiAjaxLogin=t rue";
xmlhttp.open("POST", "http://www.mydomain.com/j_acegi_security_check", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); // Setando Content-type
xmlhttp.setRequestHeader("Content-length", dados_a_enviar.length); // Comprimento do conteúdo=comprimento dos dados a enviar
xmlhttp.send(data);
}

I set my spring-security.xml authentication processing filter to


<property name="filterProcessesUrl">
<value>/j_acegi_security_check</value>
</property>
<property name="authenticationFailureUrl">
<value>/login.html?login_error=1</value>
</property>
<property name="defaultTargetUrl">
<value>/index.html</value>
</property>
<property name="authenticationManager">
<ref bean="authenticationManager"/>
</property>

The Post is made correctly (Receives 200 response). Tomcat creates a session after the post, but my ajax request is empty.
I know that I have to do something to receives the session created, but how can I do that ?
How can I do a login from a external site ?

Thanks,
