Re: refresh views after calculation in thread have finished

Andre,

In reference to your question:

If your Runnable implements Serializable, you can put it in the user's
session with PortletSession.APPLICATION_SCOPE... this will make it
available to servlets as well.  You can then use ajax polling or something
similar to query a servlet and check if the process is complete, and then
update the portlet's view with the result.

HTH,
