Lucene is supposed to be really powerful.

has some articles related to Lucene. The Javaworld one pretty much put Lucene at the top of the Java based search engine api's.

Explicitly invalidating sessions while users login /logout to Portal
Posted by Asif Jan <as...@cern.ch>.
Hi
I want to explicitly invalidate sessions when users click "logout" on the
portal page. I am using jetspeed action JLogoutUser to logout the users .
And have implemented my CustomAuthentication class which has login and
logout methods . Everything works fine if I dont play with sessions , but if
I try to invalidate session in CustomAuthentication.logout method I get
InvalidSessionState exception.
PLUS
I also need that session shall only be created when a user logs in , where
as jetspeed creates session when we visit the Home screen .
Thanks
Asif

Posted by Joachim Muller <jo...@wemove.com>.
Hi David.
i am working on a project where the user is very restricted
in personalisation terms. in fact only HOME can be personalized.
mostly all other pages are based on screens, not on portlets.
my first idea was to create a spider daemon for every role, indexing
the role specific content. (the spider logs on as the roles default
user.) this seems to be the easiest way to add full text search,
although it's a hack and not perfect (personalised pages are not
indexed correctly, actuality issues due to time lag between spider runs,
performance). but in our case it would be sufficient.
( sorry, i'm just brainstorming now ;-) and i am not a jetspeed
specialist. )
adding only the content that the USER has access to would be much
better. with a mixed screen/portlet application the only way I
can think of is to create a userbased fulltext index with a spider.
with a lot of users this would be a lot of performance loss for
the 'real' users, due to stupid indexing.
to index on publication would be much better. (Add Portlet will only
work with static content.) but this approach can be very complex
(every portlet should register with an index manager and should be
able to report changes. the index manager should check for every
user if the portlet is accessible, construct the appropiate URL
and update the index. changes of the psml should trigger the
indexer as well. user specific indexes are still required.)
maybe another way would be to show only the specific portlet as
the search result and not the psml page. but still user specific
indexes would be required.
(i really would like to know how commercial portal toolkits handle
the user specific indexing issue.)
just read scotts mail
yes that's right the solution could be a indexer interface the
portlet author can implement.

Well my first example Lucene portlet indexes the Jetspeed documentation
online.
The customize view would allow the user to add a URL to the index.
Another idea we are thinking of us indexing the xreg files and adding a
fulltext search to the Add Portlet feature.
Haven't tried that though.
Anyway Im open to ideas and suggestions.
I think every site will have its own content, so the first portlet is
just an example of how it to do it.

this is really good news! :-)
just a question. are you working on searching
lucene indexes from within the portal or do
you also have a concept to CREATE a lucene
index based on the portal content (fulltext)?
the second topic has many questions I am not
able to answer very well:
- personalisable pages with different content
- user specific content
- variable meta tags (INDEX FOLLOW) in the default
templates
- session ID's in the url
did anybody think about that or has experiences
with other solutions (e.g. websphere)?

Torque DataSources and the DatabaseBrowserPortlet?
Posted by jc...@drhorton.com.
Is there any docs or site that discusses how to setup additional data sources for the DatabaseBrowserPortlet? I've setup the primary but I'm kind of unclear how to setup
additional data sources.

We've already started on Lucene integration, see the CVS head under
org.apache.jetspeed.services.lucene. .
Im working on a Lucene Portlet which uses the Lucene service.
It should be committed in the next day or two

I would be very excited to see that portlet in action.

I'd second the use of Lucene. I think it's the most advanced out of the open
source Java search engines. The OnJava.com articles are very good, or if you
