Refreshing Discoverer Portlets

Question

Using 9iAS R2, we have set up discoverer portlets on our intranet and have serveral scheduled worksheets which display within portlets.
On one report I have scheduled it to run once an hour and I have also set the Discoverer worksheet porlet to refresh on an hourly basis - which it seems to do.
However, the data is not updating at all. It is only when we actually open the worksheet using Discoverer Plus and save that data in the Portlet refreshes.
When users click on the 'view worksheet' link and open Discoverer Viewer the correct data appears
Perhaps I have missed something . . is there another way to ensure that the data shown in the portlets is refreshed?

Answer 1

I believe that the refresh is set as a DBMS_JOB in the database, however, I have no clue where this is set, obviously somewhere in the product and/or identity metadata database depending on your configuration. Something that might be an easier solution is use something like HTTPClient from the Apache Foundation (http://jakarta.apache.org/commons/httpclient/) and write a small app that logs into portal as an administrator and then calls each portlet's refresh URL in order. It know its a workaround, however, it should work, that being said I've never tried it. I don't know if I'll get time to write it, but if someone gets a chance to write it before I do please shoot me the code :P
