Mediawiki Integration with Labs (stable)

philnicholls

Hi all,

I think I have had mediawiki successfully integrated with Alfresco labs 3c in the past (i.e. I could browse wiki content, but not edit it, from Alfresco).

I've now moved to labs stable, but I get an install error:

Has anyone successfully managed to get mediawiki to work with Alfresco labs (stable)? [or should I just go back to 3c 🙂 ]
Thanks
Phil

I also spent a few hours this morning trying to get this to work. Got the exact same error.

This was tested on ubuntu 8.10, Tomcat (bundled), MySql, and Java6. Verified that phpIntegration worked before moving on to mediawiki module.

I got the same issue for my fresh installation. Also verified that phpIntegration worked before installing mediawiki amp. Can anyone help?

mederic

Hello

I have looked at the Java source code to see what changed between the 3.0.0c and the 3.0.0stable. These are my conclusions:

In the 3.0.0c, modules were executed using system user credentials. This is not the case with 3.0.0stable: modules are executed using anonymous credentials, and as they are not allowed to, Java exceptions are thrown.
I modified the classes "org.alfresco.repo.module.ModuleComponentHelper", "org.alfresco.repo.module.ModuleServiceImpl", "org.alfresco.repo.admin.registry.RegistryServiceImpl" and several XML files, rewriting the references concerning "AuthenticationComponent" objects which existed on the previous software releases.

It seems to work fine on my development server, but I advice you to wait for a new official release of the software to deploy on your production server, all the more since there is probably a good (security) reason why Alfresco developers removed system user credentials for modules launcher.

Hi Meredic,

thanks for telling us what you found. This is very useful.

It would be interesting to get a response from an Alfresco engineer on this. It sounds like a major bug.
Maybe it should be reported as a bug?

Any rumours on when a new release of Mediawiki will be available?

hanzo

I m also looking for the mediawiki integration for Alfresco Stable. I try the amp file from the http://wiki.alfresco.com/wiki/Labs_3_Final_download_files but i got an install error like the other posting here.

Any ideas?? :roll:

hanzo

Hi,

I try also the amp file from http://dev.alfresco.com/downloads/nightly/dist/ without success. or I have to modifie the classes??

Can anyone help? :roll:

Hello Hanzo,

this is the wrong amp for 3 labs???

Your version of the amp file is the lastest one. But as I said in my previous post, it does not work with Alfresco 3.0.0 stable apparently because of new security rules for external module launch.

or I have to modifie the classes??

I see 2 solutions for you:
- you download the Alfresco source files and you modify the classes as I described in my post (it's been working very fine on my server for almost 1 month)
- you wait for the next release of the software

:arrow: So, my question to Alfresco developers: when will a new version of the software be published?
Thanks,
Mederic

Hi Meredic,

I asked Alfresco engineer MikeH and he said it should be raised as an issue in the JIRA, if not it won't get attention. Since you're the originator it seems best you do it. If not I can do it.

mikeh

Bugs (or suspected bugs) should always be raised in JIRA - that's the only place we prioritise such things.

Thanks,
Mike

This problem is posted on the Jira site here:

https://issues.alfresco.com/jira/browse/ALFCOM-2585

Go out and vote for it if you want it to get prioritized for getting fixed.

Hello

I have looked at the Java source code to see what changed between the 3.0.0c and the 3.0.0stable. These are my conclusions:

In the 3.0.0c, modules were executed using system user credentials. This is not the case with 3.0.0stable: modules are executed using anonymous credentials, and as they are not allowed to, Java exceptions are thrown.
I modified the classes "org.alfresco.repo.module.ModuleComponentHelper", "org.alfresco.repo.module.ModuleServiceImpl", "org.alfresco.repo.admin.registry.RegistryServiceImpl" and several XML files, rewriting the references concerning "AuthenticationComponent" objects which existed on the previous software releases.

It seems to work fine on my development server, but I advice you to wait for a new official release of the software to deploy on your production server, all the more since there is probably a good (security) reason why Alfresco developers removed system user credentials for modules launcher.

Mederic

Medric,
Any chance you could/would share your changes? We need to get moving with a MediaWiki on Alfresco deployment and hate reinventing the wheel.

Thanks in advance,

Hi

I have tried your solution by reverting all the changes in the classes you mentioned, but when I deploy the new classses into alfresco, I get the following error:

It seems I am not setting properties for this right, but I could not find out how or where should I set them. Can you share your changes in several XML files that you mentioned so I can make this work?

Kind Regards
Erdem Bayer

plexi

Did anyone get this working? Could you share a patch?

aluxh

I am looking for the solution to get the Mediawiki work in Labs (Stable) as well. Any kind souls to guide me?

ecmeins

I too am looking to implement the mediawiki amp file against Labs 3 (stable). Vote has been cast in the JIRA for a fix and I will gladly test any patch recipes against my dev install while awaiting an update.

Thanks,

Eric

philnicholls

Wow, I'm sort of a bit gobsmacked that it's nine months later, we're now on Alfresco v3.2, and this is still broken.

If it's not been fixed, then why is the amp file included in the download area? Or am I missing something?

miudon

Hi!
Unfortunately, I have the same problem with Alfresco Community 3.3.0 (2765) schema 4009 - Originally installed version 3.3.0 (2765).

mfischer

Same for me (3.2r, 3.3g) - would be fine if anyone could upload the modified class-files…

mfischer

Attention: I'm not a developer, just only a sysadmin, i.e. I don't really know if this opens security holes. It should not affect other Alfresco components, but rmember - you've to do this at your own risk!

For those who still want to try the MediaWiki extension with the actual ALF CE releases: This way I got the extension running with ALF CE 3.2r and 3.3g (the hint came from the JIRA-ticket:

At first setup a SVN environment as discribed here or there (did this a few month in the past, don't remember the exact steps

), I use Eclipse Galileo with a complete HEAD copy, but it should be possible with the pure mediawiki extension sources from the SVN, but you will have to write your own build.xml-file, I guess. If you commonly deal with Java you might be able to use the pure sources with "javac" executable at the commandline.

Important is the MediaWiki Integration-tree, where the MediaWiki extension is located. In this subtree look at source/java/org/alfresco/module/mediawikiintegration/MediaWikiService.java. This is the module which has to be modified.

But at first have a look at the tree, none of its components must show red symbols at its icons (this belongs only to this special tree, it doesn't matter what other trees are showing). If there are some, you have to resolve these errors first, usually by correcting pathes or java compiler settings. For more information about this use the Alfresco Developer Guide.
To setup Eclipse to compile modules automatically makes things more easier.

Load the MediaWikiService.java into the editor by double click on it. Search for the following string: "public void onCreateNode" or klick "onCreateNode" in the object browser on the right side. This is the first procedure we want to change. Add the following lines:

&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;// Added for repairing the broken MW amp
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;AuthenticationUtil.setRunAsUserSystem();
‍‍‍‍

Now it should look like this:

&nbsp;&nbsp;&nbsp; public void onCreateNode(ChildAssociationRef childAssocRef)
&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Added for repairing the broken MW amp
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; AuthenticationUtil.setRunAsUserSystem();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // The newly created mediawiki space
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NodeRef mediawiki = childAssocRef.getChildRef();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Set the default values for the various configuration properties
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String wikiName = (String)this.nodeService.getProperty(mediawiki, ContentModel.PROP_NAME);
…
‍‍‍‍‍‍‍‍‍‍‍‍

After saving the document Eclipse recompiles the class file automatically (if setted up to do this, otherwise do it manually).

Now it would be possible to implement the extension to a running Alfresco installation, but for working with it there is another necessary, otherwise you would not be able do delete wiki spaces later.

Go to the onDeleteNode procedure and add the code as shown above, it should look like this (the original procedure is empty):

&nbsp;&nbsp;&nbsp; public void onDeleteNode(ChildAssociationRef childAssocRef,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; boolean isNodeArchived)
&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Added for repairing the broken MW amp
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; AuthenticationUtil.setRunAsUserSystem();
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; }
‍‍‍‍‍‍‍‍‍

Save (and compile) it again, change to a file manager and look for the file "MediaWikiService.class" in the Eclipse workspace path. In my installation it is located at "c:\workspace_alfresco\alfresco\HEAD\root\modules\MediaWiki Integration\build\classes\org\alfresco\module\mediawikiintegration\", but that depends on how you configured your dev-environment.

This file has now to be inserted into the alfresco-mediawiki-integration-<ALF-VERSION>.jar-file, which is part of the MediaWiki-AMP. download the AMP-File for your Alfresco version, for 3.3g you can use the 3.4dev-version from here, because no official package for 3.3g has been released.

Open the AMP-file with a zip program like 7-zip and got to the "lib"-folder. Open the the JAR-file (7-zip can do this without unpacking it) and copy the newly compiled "MediaWikiServices.class" into the subfolder "\org\alfresco\module\mediawikiintegration\" by overwriting the old file. Close the zip program and confirm the request for saving the changes.

Copy the modified AMP-file to your Alfresco server and install it the common way (don't forget to install the php integration module first) or inject it in a running - but broken by MediaWiki - Alfresco instance.
After installing it and cleaning the Tomcat working directories start Tomcat and have a look at the system/catalina log: it should show some database commands instead of java errors. If you can see this, you're done
