Which portlet class are you using? One from the distribution or a portlet
class of your own? I am using Jetspeed on an Intranet; one of the portlets
on the users home page is a summary of their daily schedule - this requires
an update every time the page is refreshed, ie, it cannot be cached. I'll
share with you our solution (though be warned that the PortletAPI
discussions may - or may not - alter this in the future)
Assuming you are using an existing portlet class, here is what I would
suggest. (I'll use RSSPortlet as an example):
- copy \src\java\org\apache\jetspeed\portal\portlets\RSSPortlet.java to
...\RSSCurrentPortlet.java
- Modify the RSSCurrentPortlet.java. Add the following method to the class.
/* tells jetspeed not to cache this content*/
public boolean isCacheable ( )
{
return false;
}
- modify the jetspeedconfig.jcfg to use RSSCurrentPortlet instead of
RSSPortlet
- Run the build scripts to create your jar/war file(s).
Now you won't have to sacrifice the performance of the entire system to
support this single portlet! I had actually modified many of the portlets so
I can pass a parameter indicating whether the portlet should be cached.
(Basically, read the parameter in the init() method, then return that value
in the isCacheable() method rather than always returning false)
HTH,
