portlet alfresco2.0

I'm very interested too.
Any news?

Hi, if you want, you just have to download the alfresco.war, add it the 3 xml files and deploy it with the Liferay auto deploy.

Good luck

It's done but I've the following errors :

Any idea?

Oh, i think your error is a duplicate librairy in your tomcat app server.

So you should remove "portlet-api-lib.jar" from "webapps\alfresco\WEB-INF\lib" and try to restart your Tomcat.

I hope it is that…

Thanks a lot for your advice.
It works perfectly now.

Thanks again SÃ©bastien.

Hi, if you want, you just have to download the alfresco.war, add it the 3 xml files and deploy it with the Liferay auto deploy.

Is this for alfresco 2.0? i canÂ´t find xml files for portlet definitions!
where are they?

Thanks!

yes, it is for Alfresco 2.0. So you can take the Alfresco 1.4 xml file to use them with 2.0.. it works fine.

Good luck.

Hello all,
we are starting a project where we are going to develop a set of portlets exposing Alfresco ECM (and possibly WCM) contents through Liferay portal.

The main application which will be used for inserting content will be Alfresco Web Client while the portlets will deliver the published content.

One of our open points is the alfresco APIs that we will use to develop the portlets which access the alfresco ECM managed content.
We want to be able to phisically decouple alfresco from liferay, thus our portlet should be able to access one content repository possibly shared by multiple portal servers (front office) and multiple alfresco web clients (back office).

One option is to use Alfresco Web Services. They allow to have alfresco and liferay on different servers, but at the moment they do not expose the full set of available functionalities. In addition the SOAP protocol could introduce some overhead. The roadmap of the 2.1 release states that the full set of web services will be available. Could you confirm this ?

It looks that the Alfresco Foundation Services API would allow to exploit the full set of available services, but we do not know if it is possible to deploy portlets (in general on more servers) which access the same content repository (shared also by the alfresco Web Client application) by using the Alfresco Foundation Services API.
If we understand correctly, this architecture looks feasible according to the http://wiki.alfresco.com/wiki/Alfresco_Repository_Architecture, deployment Option 3 "Clustered Repository Server", where each web server could be one liferay instance with our portlets or an Alfresco Web Client.

Is our interpretation correct ?
In general, which API do you suggest to use ? (or would you use to develop the Portlet SDK you are mentioning?)

Thanks,
Adriano

adriano

Thank you very mutch for your quick answer.
Actually it looks that web scripts could allow us to develop most of our content delivery needs.
Just one question…
Could you anticipate when Web Scripts service will be available, at least for starting the developments (the wiki refer to the 2.1, scheduled as beta version for mid of April) ?

yes, it is for Alfresco 2.0. So you can take the Alfresco 1.4 xml file to use them with 2.0.. it works fine.

Good luck.

I have copied portlet.xml, liferay-display.xml and liferay-portlet.xml but the error is:

Not very descriptive…

Hi, remove portlet-api.jar from your tomcat lib and it will be fine.

Thanks Sebastien! now the portlets are registered!

But another error iÂ´m working on now:

IÂ´ll take a look and post solution here, I hope…

This exception happens in Windows, but now we have deployed on Linux and everything is fine!
At the end, we have Liferay and alfresco 2.0 portlets. Now we will try single sign-on. Can someone give me some guidelines or links? Thanks!

I'm very interested too, but it seems to be a hard job.
Have a look to :
http://wiki.liferay.com/index.php/Single_SignOn_-_Integrating_Liferay_With_CAS_Server

Maybe it can help you…

Arnaud

Hi, it looks like very hard…

So, integrate CAS filter with Liferay is fine but the auto login in SSO with Alfresco portlet is hard.

You have to read the authentication protocol in CAS and you will be afraid of the implementation of the filters. I explain. the filter are called when a login url is called for exemple…ok… the filter CAS ask to the CAS api if there is a ticket for that webapp and for that httpsession. So CAS server say no and redirect the user to the cas login page…. al is fine.
You write login/password on the login form, CAS server make a ticker for Liferay (or Alfresco) webapp and redirect the user to the CAS filter. The cas filter is just looking for a "CAS user name" in the httpsession.

So, it should get the ticket number in the httprequest and validate it with the cas server… this is not done in the CAS filter.

So ther is a lot of work to perform a good CAS implementation , an Alfresco autologin and a CAS filter for alfresco portlet…

I am working on…

Good luck.

Hi Sebastien,

yes, it looks difficult, is there another way to enable SSO without CAS? another way we could investigate at the same time and share experience about both methods in the forum.

I mean, maybe itÂ´s possible to create an alfresco URL to login and do in some hidden way to user…

Thanks!
