Drop spot not working

[cmathew]

Hi

I clicked on Drop spot from the "File" drop down menu. It loaded a Java application as shown in the attached image. But dragging and dropping files or folders to it does not do anything. I tested with Firefox 9.0.1 and Safari 5.1.2 on Mac. When using Firefox the following error is reported in server log. But with Safari no error is logged on server.

This is not a bug, please check that your folders tree is EMPTY. This is because you entered with a user without groups or with a group that doesn't have read permission on the root folder.
In this case the applet runs but the server cannot store the files because of no folder was selected.
Please retry with a good user.

The issue persists as admin user too. I was logged in from Firefox as admin user and the server log reported the error I pasted before.

Thanks

[cmathew]

The issue with new user from Safari was indeed permission related. But now that permission is corrected this user exhibits the same issue as admin user - "Server error".

Please completely delete the cache of the Java plugin, and if possible disable the cache at all.
The cache of the java plugin is shared among all installed browsers.

 http://www.java.com/en/download/help/plugin_cache.xml

When done close all the browsers and retry

[cmathew]

I emptied the cache from Java Preferences. And restarted the browser. Upload still fails for both admin user and another user. Same error.
Local Java logs show this as the last event reported:

<message>Upload triggered

Unable to reproduce your case, please send email to support@… to agree on a date and time to connect to your server.
