This guide helps you get started with Meveo. It covers server configuration and use of the default database. Advanced deployment options are not covered. For a deeper description of features or configuration options, consult the other reference guides.


Installation Guide

This guide is intended for Windows users. Minor changes to the instructions must be done to become applicable to other operating systems.


  1. Install or extract the OpenJDK in your PC.

  2. Set the environment variable JAVA_HOME, make sure it points to where you installed the OpenJDK. In Windows explorer, right click on This PC / Properties / Advance system settings / Environment variables / New. Refer to this guide.

  3. Add %JAVA_HOME%\bin in the Windows Path environment variable. Refer to this guide.

  4. Open a Windows command prompt and type "java -version", hit enter. The Java version installed on your system should be shown.


  1. Download and install Git.


  1. Download and extract the maven archive into your PC.

  2. Add the M2_HOME with value pointing to where you extract maven to your Windows environment variable. See what we did in Java above. Add the %M2_HOME%\bin folder to your Windows environment path just as we did with Java above.

  3. Open a Windows command prompt and type "mvn -version", hit enter. Just like Java it should give us the version of maven installed.


  1. Download and install PostgreSQL. Take note of the admin password as we will use it later.


  1. Download and install PGAdmin.

  2. Open PGAdmin, it might ask you for a master password. Enter a password and make sure to remember it.

  3. In the left panel, expand Servers / PostgreSQL 9.5.

  4. Right click Login/Group Roles and select Create / Login/Group Role.

  5. Under General tab set Name=meveo.

  6. Under Description tab set Password=meveo.

  7. Under Privileges tab toggle Can login and Superuser.

  8. Hit Save.

  9. Back in the left panel, right click on Databases and select Create / Database.

  10. Under database tab set Database=meveo, Owner=meveo.

  11. Hit Save.

Wildfly and Keycloak Installation

Option 1 - Installing as Standalone Serversw.

  1. Download and extract Keycloak to your PC. Let’s call the folder where you extracted the files KEYCLOAK_HOME.

  2. Open the file KEYCLOAK_HOME/standalone/configuration/standalone.xml.

  3. Find this line <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}"> and replace the port-offset:0 with port-offset:1. This means 1 will be added to all default ports. Making the oauth url available at port 8081.

  4. To start the server run KEYCLOAK_HOME\bin\standalone.exe.

  5. Try accessing http://localhost:8081 from your web browser.

  6. Create an initial admin user by entering a username and password and proceed to login. You should be able to arrive at the Keycloak admin interface.

  7. In the left panel, hover on Master and click Add Realm.

  8. In the right panel, click Select a file and choose meveo-realm.json file. Meveo Realm

  9. Click create. The Meveo realm should be created and it should now be the selected realm.

  10. Back in the left panel, click Import / Select a file and select meveo-users-0.json file. Meveo Users

  11. Hit import.

To check if meveo realm is correctly configured:

  • Click the Users menu and you should see 9 users.

  • Click the Clients menu and you should see meveo-web.

In the eclipse section, we will discuss how we can integrate Keycloak so we can start it from there.

  1. Download the PostgreSQL driver.

  2. Download and extract Wildfly into your PC. Let’s call the folder where you extracted the files WILDFLY_HOME.

  3. Inside WILDFLY_HOME/modules folder create this folder hierarchy org/postgresql/main.

  4. Navigate to this folder.

  5. Copy and paste the PostgreSQL driver (postgresql-42.2.4.jar) here.

  6. Create a new file module.xml with the content below.

<?xml version='1.0' encoding='UTF-8'?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
        <resource-root path="postgresql-42.2.4.jar"/>

        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
Add the Keycloak Adapter to Wildfly
  1. Download the Keycloak Adapter with the same version as the downloaded Keycloak Server.

  2. Copy the downloaded file into WILDFLY_HOME and extract.

  3. Run command prompt and navigate to WILDFLY_HOME\bin folder.

  4. Open WILDFLY_HOME\bin\adapter-install-offline.cli and change the standalone to standalone-full.

  5. Execute: jboss-cli.bat --file=adapter-install-offline.cli.

  6. A success message should be shown.

Add System Properties
