Question

I am trying to post image to user wall using javascript FB.api. Image is generated from a java servlet dynamically, but due to asynchronous behavior before the image is generated it passes control below the block to post image to Facebook part.
I want either

1. how can I make fb.api post to Facebook call from servlet?
2. how to deal with this behavior so that control will not passes below before image generation?

note servlet is working file and generating image .

var imgURL="http://xxx.xxx.xxx.xxx:8084/myapps/app1?monthly="+monthly+"&recent="+recent+"&likes="+likes;

//var imgURL="http://xxx.2xx.xx6.1x8:8084/WebApplication6/image";
alert('image');
//var imgURL="https://graph.facebook.com/100000329585395/picture";
var img = document.createElement('img');
img.src =imgURL;
document.body.appendChild(img);


FB.api('/me/photos', 'post', {
message:'image',
url:imgURL        
                       }, function(response){
                           alert('here');

if (!response || response.error) {
    alert('Error occured'+response.error);
} else {
    var postId = response.id;
     alert(postId);}


});

Check RESTFB Api which is a Java API. You can use this instead of Javascript API.
