Setting up NEXUSe2e

Out-of-the-box Installation for Windows

If you are running a Windows system, you can download the Windows installer for NEXUSe2e server in the Download section.

The installer package includes everything you need to run NEXUSe2e server. It includes an Apache Tomcat server, a Java Runtime Environment (JRE) and an embedded database (you should switch to a different SQL database for production).

The installer registers the Tomcat server that runs NEXUSe2e as a Windows service. After the standard installation procedure you will find shortcuts in your start menu, that enable you to start/stop the service.

When the server is started, you can log in to the admin interface by pointing your browser to http://localhost:8080/NEXUSe2e. The default administration account is admin with password admin. Now you can configure the server for messaging. You can find a step-by-step guide below.

Manual Installation


The current version 5.0.x of NEXUSe2e requires:

  • Java 7 (JDK or JRE 1.7.x) or higher
  • A Servlet container supporting the Servlet API version 2.4 or later (e.g. Apache Tomcat 5.5)

NEXUSe2e server comes with an embedded Apache Derby database, for evaluation and development use. We disadvise you from using the embedded database in a production environment. If you want to run NEXUSe2e server in a production environment, you also need:

  • An SQL database that can be accessed through JDCB (e.g. MS SQL Server, Oracle, DB2, MySQL, PostgreSQL)

Installing Your Server

  • Download the WAR file from the Download section
  • Deploy the WAR file in your servlet container.

    To deploy the WAR file please follow the instructions of your Servlet container/Web application server. For Tomcat the deployment is as easy as copying the WAR file into the<Tomcat root>/<webapps> directory and starting Tomcat. This will expand the WAR and start the Web application.

    The default WAR configuration will create a Derby database and pre-populate it with a basic sample configuration. The database will be created in the directory <NEXUSe2e Web app root>/WEB-INF/config/database/derby and be named NEXUSe2eDB.
  • Log in to the admin interface and configure the server.

    Start your web browser and point it to http://<server>:<port>/<deployment_name>. For Tomcat running the default configuration on the local machine, the url is: http://localhost:8080/NEXUSe2e. If you have not chopped the version substring, e.g. _4.5.1, from the war file's name before deployment, you probably need to append it to the URL.

    The default administration account is admin with password admin.
