A:
"Without having to refresh the page"
That's what Ajax is all about I suggest that you take a look to some Ajax enable JSF framework, like Richfaces, if you're using JSF 2.0 you can use Ajax behavior by default.
With Richfaces you can use the <a4j:poll> to check after some period of time if the asynchronous process have finished, you can then re-render the appropriate message.
<a4j:poll interval="1000" enabled="#{notificationBean.isTaskComplete}"
reRender="completeMessagePanel" />
Thats the general Idea.

yes, that's right, i'm using icefacesi think i could make a function that constantly ask if the process has finish, like an alert system, I thought that could be done from the servlet

Hi, I dont know much icefaces, but it seems that you can have what they call a "server-initiated rendering" http://www.icefaces.org/docs/v1_8_2/htmlguide/devguide/AdvancedTopics2.html#1075177. Probably you can do the same from your managed bean, once and your process have finished.
