 /**
 27  
  * Simply abstracts from the JavaScript callback to a Java object.
 28  
  * 
 29  
  * <p>
 30  
  * The usage is quite easy but can be tricky since varargs are used in the class
 31  
  * constructor.<br/> The requestor expects a JS method callback with variable
 32  
  * arguments size.
 33  
  * </p>
 34  
  * <p>
 35  
  * e.g.
 36  
  * <code>window.parent.OnUploadCompleted(101,'some/url/file.img','file.img','no error');</code>
 37  
  * </p>
 38  
  * <p>
 39  
  * The UploadResponse constructor behaves the same way by simply calling it
 40  
  * with:<br/>
 41  
  * <code>UploadResponse ur = new UploadResonse(SC_SOME_ERROR,"/some/url/file.img","file.img","no error"):</code>
 42
