I found javacript that gets current username, how do I set a variable in the servlet to the javascript variable?

<script type="text/javascript">
$(document).ready(function(){
var userLogin = $().SPServices.SPGetCurrentUser({
fieldName: 'Name',
debug: true
});
$('#login').text(userLogin.toString());
});
</script>
...
public String getUserName()
{
return userLogin;
}

In simple words: you can not, Javascript and servlets are totally different, one runs in browser and one on server.
You can use ajax or a simple GET/POST to send the variable value to server.

Return the value in the Servlet as the value of a hidden control and access it using JavaScript.

It may work better if the textfield was hidden, unless of course you want the user to see this textfield on the screen.
