Is Jetspeed appropriate ?

Hi Jetspeeders,

I need to build an intranet portal for a big company (15,000 potential
users, probably more likely to be around 4,000-5,000 active users). I
haven't been following Jetspeed for the past year and I need your help
to know if it can be used on that project.

Let me give you more details on what features I would need. I would very
much appreciate if you could tell me how much I would need to work to
make that happen using a Jetspeed infrastructure ... :-)

Could you rate with the following scale :
* 0 : not possible, 
* 1 : lots of coding to do, this is not a built-in feature,
* 2 : a little coding to do, but very well in the scope of jetspeed and
a known feature
* 3 : exist as a feature, can be used as is or through some
configuration but with no coding required

Features needed :

- Ability to map the authentication and authorizations to an existing
LDAP schema.
- Ability to display portlet list based on user role or other criteria
coming from LDAP (such as the Office Branch of the employee)
- Ability to customize the content of a portlet based on user role,
language, country, and other parameters coming from LDAP (employee
branch, etc)
- Any JAAS support ?
- Page content parsing for URL rewriting : I can see there is already a
URL rewriter (actually a new implementation seem to be in progress). How
much would I need to code/debug/improve to make it a reliable and fast
solution ?
- Fine-grained Portlet caching : per user, per URL (including HTTP
parameters)

Also :

- Performance : All the jetspeed web sites I have seen were not
particularly fast. Is there any known issue WRT performance ? Do all the
performance issues come from aggregated content or is the Jetspeed
framework itself (or Turbine) a bottleneck ? Or is it Tomcat (does it
make a difference running jetspeed on Resin) ? Is there any work going
on at the current time to improve performances ?

- I think IBM is using Jetspeed as the base for WebSphere Portal Server.
If so, is IBM working on a new branch of Jetspeed or are they working on
the same Jakarta CVS version ? 

- We plan to use mostly the WebPage Portlet (with caching of course) and
the JSP portlet. Any issues with these 2 ?

- Has anyone developed any Web SSO feature for the WebPage Portlet (for
example supporting Basic and form-based authentication) ? For example,
for each Application you could configure a SSOWebPagePortlet in the
config file, passing SSO parameters and reading credentials from a
store.

Overall, would you recommend using Jetspeed for a full fledge intranet
of such a size ? Would you use it yourself for that ? Do you foresee any
issue ? 

Lots of questions ... ! 

Thanks a lot for your help
-Vincent

RE: URL rewriter

Posted by David Sean Taylor <da...@bluesunrise.com>.
The new rewriter code is under org.apache.jetspeed.util.rewriter

I haven't yet attached it to a portlet, but there is a SampleRewriter
that you can start with.
The basic idea is to make it more extensible - so that you can customize
the rewriter to your needs.
I've found that I always end up writing little pieces of custom code to
handle specific tags, and that is where the events come in.
You can override the tag events to customize your rewriter behavior.

The current WebPagePortlet doesn't use the new framework yet.

URL rewriter

Posted by Glen Carl - CSC <ca...@csc-monterey.com>.
David,
I recently noticed your post mentioning that you have written an 
improved URL rewriter. Do you have a plan when you are going to 
contribute the source, or a way to access this source?

At the moment, I am in need of URL rewriting functionality for a 
Jetspeed portlet. Currently, I am using the IFramePortlet, but I have 
some requirements for something more similar to the WebPagePortlet.

Thanks,
Glen

I realize this doesn't solve the issue with session vars but...

Have a look at JetpseedResources.properties (I'm using a recent CVS 
version).  There are some settings that may be of interest to you:

# Auto-Account-Disable Feature         
services.JetspeedSecurity.logon.auto.disable=true

# 3 logon strikes per 300 seconds and your out
services.JetspeedSecurity.logon.strike.count=3
services.JetspeedSecurity.logon.strike.interval=300
# dont allow more than 10 over any time period
services.JetspeedSecurity.logon.strike.max=10

Have you tried setting "logon.strike.max=3"?

RunData Obect & Sessions

Posted by Anthony Smith <an...@fedex.com>.
In JLoginUser if I add some stuff to a session do I have to add it using the
RunData object?


I am setting some stuff in a session and I used:
data.getSession().setAttribute(current_username, "username");

and it workd but I send it back to the login page do a new submit and hence
I loose the sessions variables I created, how can I keep them.

Basically I am doing something where after 3 bad login attempts for a user
they are disabled, and they are returned back to the login page telling them
that, but each time I return to the login page after less than 3 login
attempts the counter for number of bad login attempts gets lost.

Yes, 'this summer' sounds just vague enough ;)

Yes sorry to say. 
I don't want to go into comparing app servers though since I work in the
application server biz...
Recommend doing your own benchmarks

It can be improved, hopefully easily, but its hard to say until you
actually profile it.
Part of the 1.4 release plan is to improve performance.

It isn't finalized but it is coming along (Im on the expert group)
We plan to base Jetspeed 2.0 on the spec. when it is available hopefully
sometime later this year

I might be able to help if we choose to go ahead with Jetspeed :-). But
don't count too much on it at this point. The client will decide within

Yes, but I believe the most useful ones are there already, I think. I
think the biggest work is probably on SSO-enabling the WebPage one. It
would be nice to make sure that the JAAS implementation is easily
accessible from Portlets so that we can plug-in authentication schemes
for HTTP connections for example.

Yes, but that's probably not soon enough ... We'll be in production when
this happens ... (if everything goes fine !). It's not before Jetespeed
2.0, right ? And anyways, the JSR is not yet finalized.

Im working on a JAAS proposal and will start coding sometime next week.
The plan is to completely decouple Turbine Security, and make security
more pluggable.
Will implement a default Jetspeed JAAS Security manager.
For the default implementation, I wasn't planning on using LDAP, but Im
open to suggestions.

As another approach, you can consider keeping Turbine-2 security and
find a LDAP implementation.
Im not sure, but I thought that someone implemented a LDAP service for
Turbine.
Check the Turbine list.

There is the WebPagePortlet using the old URL rewriter. 
I have recently written a second URL rewriter, which is better than the
first.
You may also want to try out the IFramePortlet 

2 or 3

For the upcoming release, we will tune Jetspeed for performance.
Ive ran Jetspeed on Weblogic and other web servers.
Im also running it on Apache with several Tomcat nodes.
I think performance is something we can improve on, and is not a major
issue.

I think so. Check the mailing list. I believe David Powers has done this

Yes I would.

Issues: 
- there's a lack of diverse out of the box portlets. With the
standardization of portlets coming soon, Jetspeed will be able to use
any standard portlet.
