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.

Do you want to set a value of a servlet member in javascript ? if so.. try this... I have not tested it though..

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

It is sorta covered in the JavaRanch Style Guide.
