eXo Google Docs Extension

Edit an eXo Platform document directly inside Google Docs

Prerequisite : eXo users must have a valid Google account email (not necessarily a gmail account)

Getting Started

Step 1 : Build

Note : Instead of building from sources, you can download the last stable version on the Downloads page.

Prerequisite : install Maven 3

Clone the project with

git clone https://github.com/exo-addons/google-docs-extension.git
cd google-docs-extension

Build it with

mvn clean package

Step 2 : Deploy

Prerequisite : install eXo Platform 3.5 Tomcat bundle (EXO_TOMCAT_ROOT_FOLDER will be used to designate the eXo Tomcat root folder).

Copy the extension binaries :

cp config/target/googledocs-extension-config*.jar EXO_TOMCAT_ROOT_FOLDER/lib
cp services/target/googledocs-extension-services*.jar EXO_TOMCAT_ROOT_FOLDER/lib
cp webapp/target/googledocs-extension.war EXO_TOMCAT_ROOT_FOLDER/webapp

Create a file called googledocs-extension.xml in EXO_TOMCAT_ROOT_FOLDER/conf/Catalina/localhost with the following content :

<Context path="/googledocs-extension" docBase="googledocs-extension" debug="0" reloadable="true" crossContext="true"/>

Download the Google Drive Java Client and copy the following libs in EXO_TOMCAT_ROOT_FOLDER/lib :

  • google-api-services-drive-v2-rev5-1.7.2-beta.jar
  • google-api-client-1.10.3-beta.jar
  • google-http-client-1.10.3-beta.jar
  • google-oauth-client-1.10.1-beta.jar
  • gson-2.1.jar
  • guava-11.0.1.jar
  • httpclient-4.0.3.jar
  • jackson-core-asl-1.9.4.jar
  • jsr305-1.3.9.jar
  • protobuf-java-2.2.0.jar

Step 3 : Enable Drive API

Google Drive API

  • In the API Access page, click on the "Create an OAuth 2.0 client ID..." button
  • Fill the form with a product name of your choice, an optionnally a product logo and a home page URL
  • Click Next
  • Select the "Service account" option
  • Click on "Create client ID"
  • Download the private key and save it on your eXoPlatform server's file system

Google Drive API Access

Step 4 : Configure the extension

  • Open the file EXO_TOMCAT_ROOT_FOLDER/gatein/conf/configuration.properties of your eXoPlatform server

Add the 3 following variables :

google-docs.serviceEmail=755138841809@developer.gserviceaccount.com
google-docs.accountEmail=mygreatcompany@gmail.com
google-docs.privateKeyFilePath=/path/to/my/private/key/4314ebd80f114feef1f19ad6e8b27ad144847144-privatekey.p12

The google-docs.serviceEmail parameter is the Email address of the service account (available in your Google console, see previous screenshot).
The google-docs.accountEmail parameter is your Google account.
The google-docs.privateKeyFilePath parameter is the path to your previously downloaded private key.

Step 5 : Run

cd EXO_TOMCAT_ROOT_FOLDER 
./start_eXo.sh

Step 6 : Add the Google Docs buttons

  • Connect as an administrator
  • Go to the Content Administration
  • Content Presentation > Manage View
  • Edit the view you want to add the buttons in, for example WCM View
  • Click on the tab you want to add the buttons in, for example Publication
  • Select the 2 buttons "Edit in Google Docs" and "Check In from Google Docs"
