Seam Client for Alfresco rivet

rivetlogic — Mon, 17 Nov 2008 23:37:39 GMT

SCArSCAr (Seam Client for Alfresco rivet) is a production-ready demo application for accessing an Alfresco document management repository. SCAr is built with JBoss Richfaces, JBoss Seam and RAAr (http://wiki.rivetlogic.org/display/RAAR/).A demo site can be accessed at http://scar.rivetlogic.com.SCAr

Hi Jan,

Thanks for the catching that. I updated the wiki.

Hi,

I have installed SCAr on serverA, accessed using http://serverA_IP:8080/scar
Whereas, my alfresco is running on serverB, accessed using http://serverB_IP:8080/alfresco

I have installed CMA and SCAr amps onto the alfresco installation.

How do i point SCAr to my alfresco installation?

Also, How do i implement SSO on SCAr?

Hi,

There's an xml config file (app-config.xml) that you need to add to your app server's shared classpath. It contains all of SCAr's configuration. I added instructions on how to do that on SCAr's documentation wiki page:

http://wiki.rivetlogic.com/display/SCAr/Documentation

Look for the Configuration section.

The value for <repository-url>http://localhost:8080/alfresco</repository-url> is what you need to change to point SCAr to your Alfresco repository.

Regarding SSO we have not implemented that yet. This is probably a topic for a dedicated thread but one quick and dirty idea would be to write a custom Alfresco authentication component that takes an SSO ticket as its password value that is in turn validated by that component during the execution of an authentication chain (which would be triggered by a call to the RAAr authenticate method). This of course implies that the SSO solution in place allows for that type of validation and considers it kosher.

The more correct approach for supporting SSO would differ depending on whether or not you need to have the ability to login to Alfresco using Alfresco's web-client via the same SSO mechanism.

If there is no such need then it is possible to make SCAr itself support the SSO solution (i.e. have the ability to validate an SSO ticket and extract a username out of it) and use the method mentioned above to log the user into Alfresco without a password. You'd still need to implement some means via which the custom authentication component can trust the RAAr client, which shouldn't be too difficult.

Hope this helps,

Thanks for the solution, SCAr can authenticate with Alfresco now.

I can see the client page, but my folders are missing.

I get following big Exception on login though (Sorry for cut and pasting a big chunk of the log file)

Hi,

It seems that you're not using the correct SCAr/RAAr version combination. Please follow this compatibility matrix:

http://wiki.rivetlogic.com/display/SCAr/SCAr+to+RAAr+Dependencies

The reason is that for every SCAr release we try to use the latest version of RAAr to stay current.

Hi,

I was using cma-alfresco-1.9.0.amp but now I have re-installed Alfresco with cma-alfresco-1.8.1.amp

I get following error messages

13:22:32,536 ERROR [LoginAction] Authentication failed for user: admin
13:22:32,611 ERROR [LoginAction] Authentication failed for user: admin

This is without the DEBUG log.

Re: Seam Client for Alfresco rivet

rivetlogic — Tue, 23 Dec 2008 13:32:36 GMT

The error suggests that RAAr is unable to authenticate the admin user. I'm assuming you're using the right password so maybe it has to do with the way Alfresco's authentication is configured.

Are you authenticating against the Alfresco database or are you using a different type of auth?

–Alaaeldin

Re: Seam Client for Alfresco rivet

amitoj — Tue, 23 Dec 2008 13:38:32 GMT

I am authenticating against Alfresco database and I can access Alfresco using the Alfresco default login page.

Also, the version of Alfresco I am using is
Alfresco started (Labs): Current version 3.0.0 (c 1342) schema 1000 - Installed version 3.0.0 (c 1342) schema 1000

Everything is same except the version of CMA amp, which is now 1.8.1 instead of 1.9.0

I have just re-run the jboss using DEBUG log and the output is huge. Is there a way I can email you the log file?

Re: Seam Client for Alfresco rivet

rivetlogic — Tue, 23 Dec 2008 13:52:10 GMT

I see. That's the problem. RAAr also has a compatibility matrix with Alfresco version which you can find here:

http://wiki.rivetlogic.com/display/RAAR/Compatibility+Matrix

The reason this is the case is because sometimes the Alfresco Foundation Services' APIs change from one release to the next.

We would need to release a new version of SCAr that uses RAAr 1.9.0 in order for it to work with Alfresco 3.0.x

Is this something you need soon?

Re: Seam Client for Alfresco rivet

amitoj — Tue, 23 Dec 2008 13:58:34 GMT

Yes, I need to give a 'proof of concept' demo by 2nd week of January.
My original plan was to use the Alfresco UI, but there is too much unwanted functionality in it.

SCAr has a very neat UI compared to Alfresco and I would like to implement it.

What is the best possible ETA?

Re: Seam Client for Alfresco rivet

Re: Seam Client for Alfresco rivet

rivetlogic — Mon, 29 Dec 2008 14:35:07 GMT

Hi,

Your app-config.xml file looks ok. The paths used in that file are the same one you use in Alfresco lucene queries.

The error you're getting is this:

11:51:53,840 ERROR [TreeUtil] A CMA runtime exception occurred:
com.rivetlogic.core.cma.exception.CmaRuntimeException: java.lang.NoSuchMethodError: org.alfresco.service.cmr.security.Acc
essPermission.getPosition()I

getPoisition() is a new method added in Alfresco 3.0 which implies that you're not using RAAr 1.9.0.

The versions you should be using are:

Alfresco 3.0
RAAr 1.9.0 AMP
SCAr Alfresco 1.0.3 AMP
SCAr 1.0.3

Are these the versions you're using?

Also make sure when you apply the amps to use the -verbose argument to make sure the AMPs are being installed correctly.

–Alaaeldin

Re: Seam Client for Alfresco rivet

amitoj — Mon, 29 Dec 2008 14:41:30 GMT

The versions I am using are correct

Re: Seam Client for Alfresco rivet

rivetlogic — Mon, 29 Dec 2008 16:32:00 GMT

Hi,

We looked into this issue and found that Alfresco's 3.0 Community version (downloaded from the Alfresco website) is missing the following method:

org.alfresco.service.cmr.security.AccessPermission.getPosition()

This method is available in the Enterprise version which is what we test RAAr against.

It seems that your options are:

- Get a free trial Alfresco Enterprise 3.0 version for your proof of concept

OR

- Checkout the HEAD of the Alfresco Community source from SVN and verify that this method is there, then compile/build alfresco.war

Hope this helps,
