SCAN

Hi all,

I just tried to add a del.icio.us account to SCAN 1.3 (running in Linux with Java 1.6) for the first time, but am getting an error message:

> "Error retrieving location! The > service in unavailable or busy. Try > again later. Response parsing error."

On the command line it also shows:

Any ideas?

Thanks! Keith

Hi,

This is a known issue with Del.icio.us. In brief: Delicious server sends an unrecognizable response to your computer.

It usually means what it says: "The service is unavailable or busy" but also may be caused by throttling in the API (see http://delicious.com/help/api). Note that your account may still be working via the web, but the API service that SCAN plugin uses is a bit different thing - sometimes it goes down unless everything is ok with the web-interface.

Another attempt of adding the location after some time usually works. I however think that Delicious plugin could more smart in this situation - like to make few repeating attempts automatically before it gives up.

Hi Alexeya,

Thanks for the reply and explanation. I tried again today and sure enough it worked well :)

Perhaps an even simpler message would be to hide the error output and exception-related messages, and simply display something along the lines of "Del.icio.us is currently not responding. This is normal, and the best solution is to simply try again later."
