This guide describes how to install BellaDati WAR on Tomcat. BellaDati supports Tomcat 7.0.6 and higher. We recommend to use Tomcat 9.0.


    Tip for Windows users:
    We recommend using the 32-bit/64-bit Windows Service Installer, which allows you to run BellaDati as a Windows service.

    The BellaDati WAR file is the BellaDati application packaged in a WAR archive. It must be deployed into an existing application server and needs to be connected to a data warehouse running on an existing database server.

    Before You Begin

    Please read the following important notes before you begin installing BellaDati on Tomcat:

    • Make sure you have the right version of Java. See Installing Java for more details.
    • Deploying multiple BellaDati WAR application in a single Tomcat container is not supported. We do not test this configuration and updating any of the applications (even for point releases) is likely to break it.
    • We recommend not deploying any other applications in the same Tomcat container that runs BellaDati, especially if these other applications have large memory requirements or require additional libraries in Tomcat's lib sub-directory. Multiple applications in a container can impact stability as a crash in one application could make the entire container inaccessible. Additionally, in order to update or reconfigure any of the applications, you'll need to restart the whole container.

    1. Setup data warehouse

    Please follow the instructions on the Setting up the PostgreSQL Database page.

    2. Download and extract BellaDati WAR Archive

    Download the BellaDati WAR distribution as a ZIP archive from the BellaDati download page and extract its content using a tool such as 7-Zip for Windows or Linux's GNU tar tools. Only one of the files in the ZIP archive is used for this setup - belladati.war.

    (warning)  Avoid using Windows' built-in file extraction tool! This tool silently fails to extract files with long names. Other users have also reported problems with WinRAR.

    (warning)  Avoid using Solaris' default tar utility! Please use GNU tar on this operating system to extract BellaDati, as GNU tar handles long file names better.

    3. Configure BellaDati WAR

    Since version 2.7.14 there is no special configuration change needed, however, there are several advanced settings (e.g. enforcing the SSL), which are configurable in application.properties only.


    Configuration settings are explained in detail in the BellaDati WAR Configuration Overview.

    4. Configure Tomcat

    4.1 Configure Tomcat Context

    A BellaDati context needs to be set up in Tomcat. To do this:

    1. Create the directory structure conf/Catalina/localhost/ within your Tomcat installation directory if it doesn't already exist.
    2. Create the belladati.xml file and copy it to conf/Catalina/localhost subdirectory of your Tomcat installation directory (created in the previous step).

    3. Update the docBase attribute in the first line as well as urlusername and password in lines 5 and 6 to match your system configuration.

    Here is an example file.

    If you are installing in Windows, make sure that the paths you specify for the location of the WAR file and database are full paths with drive letters (e.g. C:\path\to\belladati.war).

    4.2 Set JAVA Environment


    If you have installed the Tomcat Windows Service, you can skip this step.

    4.2.1 For Linux/Solaris

    Before you start Tomcat, make sure you have configured the JAVA_HOME variable, which points to the installed Java SDK. You can do it in this way:

    Make sure this variable is automatically set after system starts (append it to the .profile).

    You can also specify it in the file $TOMCAT_HOME/bin/setenv.sh file (or create this file if it does not exist):

    4.2.2 For Windows

    Windows users can specify the environment parameters in the Environment Variables window.

    4.3 Set Tomcat Home Directory Permissions

    By default BellaDati is creating several directories within the Tomcat home folder. To allow this, Tomcat needs to run as a user with read and write access to this directory.

    4.4 Configure Memory Settings in Tomcat

    Tomcat memory settings need to be modified to avoid the following issue:

    • BellaDati requires more memory than what Tomcat provides by default. This may lead to OutOfMemory errors when running BellaDati if these memory settings are not increased.

    To prevent this issue, follow the instructions below.


    Please note that the value 2048MB for -Xmx (maximum memory pool) is recommended for evaluation purposes only. Please refer to the Recommended JVM Options article to find suggested settings for production deployments.

    For Linux/Solaris

    Edit $TOMCAT_HOME/bin/setenv.sh file (or create this file if it does not exist) and add the following:

    Alternatively, you can edit the $TOMCAT_HOME/conf/tomcatX.conf or /etc/default/tomcatX.conf file:

    For Windows

    If you are running 32 bit JVM on Windows, you can use max 1344MB (-Xmx1344)

    If Tomcat is not installed as a service:

    • Edit $TOMCAT_HOME/bin/setenv.bat file (or create this file if it does not exist) and add the following:

    If Tomcat is installed and running as a service:

    1. Right-click Tomcat's system tray icon and select Configure from the resulting popup menu, which opens the Apache Tomcat Properties dialog box.
    2. In this dialog box, click on the Java tab and specify the following values (depending on available system memory):



      Java Options (append to the existing value)

      Initial memory pool

      256 MB

      Maximum memory pool

      2048 MB

    For other environments and more information on memory settings, see the System Requirements.

    4.5 Modify Tomcat's server.xml

    In order for BellaDati to correctly display internationalized characters in user and group names, you need to modify the $TOMCAT_HOME/conf/server.xml file in your Tomcat installation directory by specifying the URIEncoding="UTF-8" property within the connector definition for your HTTP protocol.

    The connector definition is specified by the following element in your server.xml file:

    You should modify this element by specifying the URIEncoding="UTF-8" attribute:


    Please Note:

    • Since this property must be specified at the connector level for your application server, this setting will affect all other web applications deployed to the same application server installation running BellaDati. While this setting should not adversely effect these other web applications, you should be aware of this point.
    • BellaDati will run fine without this property set. However, you will run into issues if a user or group is created which contains international characters. Hence, it is recommended that you set this property.

    5. Start or Restart Tomcat

    BellaDati is now ready to run in Tomcat.

    Run as Service

    Start the Tomcat service used for Belladati. Restart it if it's already running.

    Run Manually

    If Tomcat is not running as a service, start (or restart) the Tomcat server with Tomcat's bin/startup.sh or bin/startup.bat scripts.

    6. Run the Setup Wizard

    Point your browser to http://localhost:8080/belladati. This starts the Setup Wizard, which will take you through BellaDati's setup procedure.
