Connect through CMIS Liferay 6.1 b4 and Alfresco 4

[Hadrien Mens-Pellen, geändert vor 12 Jahren.]

Hello Liferay forums!

I come to you to seek help because I'm trying to connect Alfresco 4.0 and Liferay 6.1 b4. I noticed a broken functionnality.

I followed Alexander Chow's tutorial : http://www.liferay.com/web/alexander.chow/blog/-/blogs/7670631, to make the connection.

I successfully managed to connect the two and can now browse and add files to Alfresco through liferay. However, when I try to move a document from one folder to another in alfresco (from Liferay) the Documents and Medias portlet crashes. In the logs I can only see that it's an internal servlet error (CMIS).

Do you guys know if ans when a correction is planned for this issue? If not, do you happen to know a workaround for this?

Thanks in advance!

Hadrien

P.S. : Please excuse my bad English

Hi Hadrien,

Sorry to hear of your troubles. At present, this is actually a bug I've been looking into and related to:

• http://issues.liferay.com/browse/LPS-23887
• http://issues.liferay.com/browse/LPS-23407
• http://issues.liferay.com/browse/LPS-23408

It seems as though what's happening is things are not getting refreshed between Alfresco and Liferay and you need to refresh the page before things work properly. It also seems to be an Alfresco 4.0-specific problem as I can't seem to reproduce the bug on Alfresco 3.2. Is this your experience as well?

Hi Alexander!

Thanks a lot for the reply! I'm glad those bugs are being looked into!

I didn't try to connect Liferay to Alfresco 3.2, we wanted to use Solr to search both Liferay indexes and Alfresco indexes.

So you can connect a repository to Alfresco 3.2 and file movement, folder deletion etc. won't be a problem?

It does not seem like this is a problem with Alfresco 3.2. But, like I said, we are still investigating this and may still be able to get things to work with 4.0.

Also, you are aware that Liferay supports Solr out of the box right? See, for example, this wiki article.

[Hadrien Mens-Pellen, geändert vor 12 Jahren.]

It would be great if the connexion could work with Alfresco 4.

Yes I stumbled upon this article, that's why I was enthusiast about Solr as a search engine for both Alfresco and Liferay.

Also, I tried to delete a folder in Alfresco, I get a stack trace in the log, but the folder is successfully deleted in Liferay and Alfresco!

[Alexander Chow, geändert vor 12 Jahren.]

That's our hope too. We want to support integration with as many technologies as possible, but if it is a bug on the Alfresco side, there is little we can control. However, we are trying our best to get to the root cause of things.

And yes, the deletion of folder bug is one of those I listed above, namely LPS-23887.

Thanks a lot!

Hello ,

Since 2 days I try to connect Liferay Alfresco through CMIS protocol following the publication
https://www.liferay.com/fr/web/jonas.yuan/blog/-/blogs/integrating-alfresco-through-cmis-in-liferay .

Here is my config:

session.store.password=true
dl.hook.impl=com.liferay.documentlibrary.util.CMISHook
dl.store.impl=com.liferay.portlet.documentlibrary.store.CMISStore
cmis.credentials.username=admin
cmis.credentials.password=admin
cmis.repository.url=http://localhost:8082/alfresco/service/cmis
cmis.repository.version=1.0
cmis.system.root.dir=Liferay Home

However when I try to upload a file to my portal I get the following error:

java.lang.NoClassDefFoundError : Could not initialize class com.liferay.portlet.documentlibrary.store.CMISStore $ SessionHolder

Note: I tested 2 Version 6.1 and 6.2 in wine.

Thank you for helping me , I am really stuck .</init>

Hey Faissal,

Did u get any solution ? I am facing the same issue.

[Khalil MEZYAOUI, geändert vor 9 Jahren.]

Hi All,

Just fixed the issue with configuration bellow (tested with Liferay 6.2, Alfresco 4):

#in portal-ext.properties:

session.store.password=true
dl.store.impl=com.liferay.portlet.documentlibrary.store.CMISStore
dl.store.cmis.credentials.username=admin
dl.store.cmis.credentials.password=admin
dl.store.cmis.repository.url=http://localhost:8081/alfresco/service/api/cmis
dl.store.cmis.system.root.dir=Liferay Home

#if ever you are behind a proxy:
http.proxyHost=
http.proxyPort=
http.proxyUser=
http.proxyPassword=
http.nonProxyHosts="localhost"

This integration will just transform your Alfresco as a "storage" for Liferay, if you look for more useful ECM integration in Liferay you can try steps here

Regards
khalil
