!!!How to Create an AJAX based file upload progress-bar dialog
This HOWTO shows how i combined [AJAX Struts File Upload Progress Meter|http://kencochrane.blogspot.com/2006/03/ajax-struts-file-upload-progress-meter.html] with a custom tweaked version of [Lightbox Gone Wild!|http://particletree.com/features/lightbox-gone-wild/] to create a user friendly upload progress bar dialog with the web page below faded out.

!Notes for usage on previous Appfuse Versions
At line 159 added 29 lines.
This tutorial can also work on previous versions of Appfuse but you need to include the dependend AJAX framewords (they are by default included in Appfuse 1.9.3). You can grap prototype and scriptaculous from Appfuse 1.9.3 and place the scrips in the same folders as where they are placed in Appfuse 1.9.3. You also need to reference the Ajax frameworks in the decorator default.jsp. Below is an excerpt of the begining of {{default.jsp}} from the Appfuse 1.9.3 project used as basis for this tutorial. You specifically needs the lines that references "prototype.js" and "scriptaculous.js" in that order since "scriptaculous.js" depends on "prototype.js". __It's important to note__ that scriptaculous.js may load additionally js scrips. And this solution in thus tutorial also needs the effects.js to be available. But in order to be safe you should include them all. They are:
*builder.js
*effects.js
*dragdrop.js
*controls.js
*slider.js
__Excerpt of the beginning of default.jsp__

#__{{ExtendedMultiPartRequestHandler.java}}__ - a slightly changed Struts controller (change marked by "Changed this section of code, that is it."). There is one important line here {{{UploadListener listener = new UploadListener(request, 1);}}} The '1' here means delay to 1 millisecond. By increasing this value uploads will take longer time but will also be less CPU intensive.
