Safari for Mac, webpage with Java applet, drag and drop area not working.

Question

At my company, we have a web page that our users access to submit media files, (QuickTime, Audio, images...), for transcoding for delivery.  The web page consists of a java applet, with an area that our users drag and drop media file into.
After updating to Safari 5.1.2, the applet will not work anymore. Instead, the browser will "open" the quicktime and play it, instead of allowing the Java Applet to do it's job.
CAN I TURN THIS FUNCTIONALITY OFF??
I read that Safari 5.1.2, (when it was initially released), broke something with the THEN current version of Java, and everyone was awaiting the latest update (build 1.6.0_29) to fix it. Unfortunately, this update did not fix my issue with the functionality of dragging and dropping media files into the web page.
It seems to me, as if, there is an over-arching functionality setting (or something) that needs to be either turned off, or in some other way DE-prioritized.
Anyone have any ideas?

Answer 1

Thanks for quick reply and help. I am able to drag multiple files but this is giving problem in case of filename with spaces like "abc def.png". Can you please put some thoughts on this.
DataFlavor uriListFlavor = new DataFlavor("text/uri-list;class=java.lang.String");
               Reader in = (Reader)t.getTransferData(DataFlavor.plainTextFlavor);
               BufferedReader br = new BufferedReader(in);
               String uriStr;
               while ((uriStr = br.readLine()) != null)
                   URL url = new URL(uriStr);
                   String category = GalleryUtils.contentsPanel.getCurrentCategoryPath();
                   GalleryUtils.generateILPFromFile(new File(url.getFile()), category);
               }Thanks
