Installing ONLYOFFICE Document Server

You will need an instance of ONLYOFFICE Document Server that is resolvable and connectable both from Alfresco and any end clients (version 3.0 and later are supported for use with the plugin). If that is not the case, use the official ONLYOFFICE Document Server documentation page: Document Server for Linux. ONLYOFFICE Document Server must also be able to POST to Alfresco directly.

The easiest way to start an instance of ONLYOFFICE Document Server is to use Docker.

Installing ONLYOFFICE Alfresco module package

To start using ONLYOFFICE Document Server with Alfresco, the following steps must be performed for Ubuntu 14.04:

1. The latest stable Oracle Java version is necessary for the successful build. If you do not have it installed, use the following commands to install Oracle Java 8: sudo apt-get update sudo apt-get install openjdk-8-jdk
2. Install latest Maven: Installation process is described here
3. Download the ONLYOFFICE Alfresco module package source code: cd .. git clone https://github.com/ONLYOFFICE/onlyoffice-alfresco.git
4. Compile packages in the repo and share directories: cd onlyoffice-alfresco/ mvn clean install
5. Upload the compiled *.jar packages to directories accordingly for your Alfresco installation:
   • from onlyoffice-alfresco/repo/target/ to the /webapps/alfresco/WEB-INF/lib/ for Alfresco repository,
   • from onlyoffice-alfresco/share/target/ to /webapps/share/WEB-INF/lib/ for Share.
   You can download the already compiled package files here and place them to the respective directories.
6. Make sure that Document Server will be able to POST to Alfresco

   You may need to change these lines in alfresco-global.properties

   alfresco.host=<hostname> alfresco.port=443 alfresco.protocol=https share.host=<hostname> share.port=443 share.protocol=https
   Probably located here /usr/local/tomcat/shared/classes/alfresco-global.properties
7. Restart Alfresco: sudo ./alfresco.sh stop sudo ./alfresco.sh start

The module can be checked in administrator tools at /share/page/console/admin-console/module-package in Alfresco.

Building from docker-compose

Other way to build ONLYOFFICE Alfresco module package is using docker-compose file.

Use this command from project directory:

Configuration

Module configuration can be found inside Alfresco Administration Console or by simply navigating to http://<alfrescohost>/alfresco/s/onlyoffice/onlyoffice-config

JWT

JWT can be configured via configuration page or by adding onlyoffice.jwtsecret in alfresco-global.properties.

The JWT configuration on the Document Server side can be found here.

Convertation

File types that can be converted

• .doc, .odt -> .docx
• .xls, .ods -> .xlsx
• .ppt, .odp -> .pptx

To convert one specific file you can simply select Convert using ONLYOFFICE action. Resulting file will be placed in the same folder. You can also configure rules for a folder, that will automatically convert files on upload or on change. You can read how such rules can be configured here.

How it works

User navigates to a document within Alfresco Share and selects the Edit in ONLYOFFICE menu option.

Alfresco Share makes a request to the repo end (URL of the form: /parashift/onlyoffice/prepare?nodeRef={nodeRef}).

Alfresco Repo end prepares a JSON object for the Share with the following properties:

• url - the URL that ONLYOFFICE Document Server uses to download the document (includes the alf_ticket of the current user);
• callbackUrl - the URL that ONLYOFFICE Document Server informs about status of the document editing;
• onlyofficeUrl - the URL that the client needs to respond to ONLYOFFICE Document Server (provided by the onlyoffice.url property);
• key - the UUID+Modified Timestamp to instruct ONLYOFFICE Document Server whether to download the document again or not;
• title - the document Title (name).

Alfresco Share takes this object and constructs a page from a freemarker template, filling in all of those values so that the client browser can load up the editor.

The client browser makes a request for the javascript library from ONLYOFFICE Document Server and sends ONLYOFFICE Document Server the DocEditor configuration with the above properties.

Then ONLYOFFICE Document Server downloads the document from Alfresco and the user begins editing.

ONLYOFFICE Document Server sends a POST request to the callback URL to inform Alfresco that a user is editing the document.

Alfresco locks the document, but still allows other users with write access the ability to collaborate in real time with ONLYOFFICE Document Server by leaving the Action present.

When all users and client browsers are done with editing, they close the editing window.

After 10 seconds of inactivity, ONLYOFFICE Document Server sends a POST to the callback URL letting Alfresco know that the clients have finished editing the document and closed it.

Alfresco downloads the new version of the document, replacing the old one.
