Configure Alfresco 1.4 and Liferay 4.2.0

[icarrara]

Hi!

Since a few days I'm trying to use the Alfresco portlet released from Liferay in the V.4.2.1 of the Liferay Portal, pointing it to an Alfresco V.1.4 on another server….

This Liferay's portlet use the Web Services Sdk of Alfresco V.1.4 server.

I'm able to see the folders structure on the Alfresco server, but I can't read nothing because I get the message "ERROR [ViewAction:80] connect timed out" when I select a file from a folder.

I hope someone could help me on this matter.

Reading Liferay and Alfresco forums, this integration is the most wanted from people but I can't get any comments on this matter …

Thank you in advance!!

Hi,

I also deployed the alfresco.war (1.4) from Liferay into Liferay 4.2.1. The Alfresco portlets works with the Alfresco in the same instance.

What changes should I do so that it connects to Alfresco running on a separate machine? Basically is there a way the portlets use web services to connect to remote Alfresco?

thanks,

Hi,

You don't need to deploy the alfresco.war on the Liferay portal if you have to connect to an already running Alfresco server.

You nee to deploy the alfresco.war only if you will install a complete new Alfresco server inside the same Tomcat instance where Liferay portal is running.

The Liferay portlet included in the Liferay portal is a Web service client based on the Alfresco Web Services Sdk… it access to the Alfresco server via Web services.

In my installation of Liferay portal I can see the remote Alfresco server on another Tomcat server in another phisical location via Internet ….  I can browse the folder structure of the Alfresco server but when I choice a file I get the error "ERROR [ViewAction:80] connect timed out" .

The problem is that no one person on the World can explain me what is this error.

I posted thi problem here in he Alfresco forum and also in the Liferay forum since 20 days but no one replyed me…

The Alfresco and Liferay integration is still a big secret…..

Thanks.

I got this to work. But I get the content only once. Subsequently exception is thrown:

It shows Bad credentials error on Liferay side. The user name / password combo are right as it connects, I see the spaces, I can navigate to remote file and then see it in Content Portlet the first time. Subsequently I get an exception.
