The Database Connector is a web application that allows you to easily integrate your forms and can be deployed under any Servlet container or run in a simple Standalone mode. The connector relies on the JDBC API. You can use any relational database as long as you have a JDBC driver for that databaseflows with your external database. The connector can be added to your  tomcat bundle. A Standalone Bundle is also available.

Info

frevvo only supports/certifies the Database Connector running in the tomcat container. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified by frevvo.

Cloud customers, who are integrating with their database in their on-premise installation and in-house customers, can choose to:

  • install the Database Connector in your tomcat bundle on their in-house server OR
  • install the Standalone Bundle on their in-house server

We recommend the frevvo-tomcat bundle for in-house customers. Follow the frevvo-tomcat bundle Instructions.

We recommend the Standalone bundle for cloud customers as no additional servlet container is needed. Standalone is also useful for in-house customers who want to run the connector on a different server than the server installation. Follow the Standalone Bundle Instructions

The Database Connector requires a JDBC driver for your database. Some pre-installed drivers are included with the connector. See Install a JDBC driver to see if the driver for your database is provided.

The Database Connector contains a working sample Derby database with BIRT and MyStore query sets and some test data. This makes it very easy to test if the DB Connector is up and running when your installation is complete.

When you complete the Installation instructions then follow the Connector Configuration Instructions - detailed steps to integrate the connector with your database.

Cloud customers must also verify connector connectivity to the frevvo Cloud Server.

  4. Locate the database-X.X.X.war file in the temp directory. Replace the X.X.X with the version of the Database Connector.
  5. Rename the database-X.X.X.war to database.war.  Replace the X.X.X with the version of the Database Connector.
  6. Copy database.war to <frevvo-home>\tomcat\webapps.
  7. Install the JDBC driver

  8. Start your server

  9. Browsehttp://<host>:<port>/database/status

  10. If the status returns failures or disabled:

    1. Review the previous installation steps.

    2. See starting and testing the connector installation for troubleshooting.

  11. When the status returns Passed for each queryset, your installation is complete

Note

Review Supported Platforms. Verify that the certified version of Java is installed and the Java_Home environment variable has been configured .

  1. Download the Database Connector Standalone bundle.
  2. Unzip the database.zip file to a location of your choice. We will refer to this directory as <db-home>
  3. Install the JDBC Driver
  4. Choose one of these methods to start the connector:

    • Method 1: Using java in a command window
      1. Navigate to <db-home>\database-connector-2.5.x .Type java -jar database.war
    • Method 2: for Windows OS

      1. Double click the <db-home>\database-connector-2.5.x\Install-Service.bat file to install the connector as a Windows service. Click the Start-DBConnector-Service.bat to start it

        Excerpt

        The Standalone Database Connector bundle includes the files shown in the image:

        Note the files in the database-connector-2.5.x directory that are used to manage the Database Connector as services on *nix and Windows operating systems: These files should be run as an administrator.

        • Install-Service.bat - installs the Database Connector on a Windows system as a service named frevvo Database Connector.

        • Uninstall-service.bat - uninstalls the frevvo Database Connector on a Windows operating system

        • Start-DB Connector-Service.bat - starts the frevvo Database Connector on a Windows operating system

        • Start-DBConnector.sh - starts the frevvo Database Connector as a *nix console instance.

        • Restart-DBConnector-Service.bat - restarts the frevvo Database Connector on a Windows operating system

        • Restart-DBConnector.sh - restarts the frevvo Database Connector as a *nix console instance.

        • Stop-DBConnector-Service.bat - stops the frevvo Database Connector on a Windows operating system.

        • Stop-DbConnector.sh - stops the frevvo Database Connector *nix console instance.

    • Method 3 for *nix OS
      1. Execute the  DB Connector.sh shell script for Unix/Linux operating systems.
    • Method 4 for Linux
      1. The Database Connector can also run as a service under Linux systemd

    It is possible to manage the Database Connector using systemd ‘service’ scripts.

    1. Copy the sample service file located in /bin/dbconnector.service to /etc/systemd/system
    2. Review it's contents and
    3. Make sure it is executable.

    You can now use systemd to manage the dbconnector service:

    • systemctl start dbconnector.service

    • systemctl stop dbconnector.service

    • systemctl restart dbconnector.service

    • systemctl status dbconnector.service

    To flag the service to start automatically on system boot use the following command:

    Code Block
    systemctl enable dbconnector.service

    Consult the service unit configuration man page for more details.

  5. Browse http://<host>:<port>/database/status - Note the standalone connector defaults to port 8081.

  6. If the status returns failures or disabled Connector Test failed then:

    1. Review the previous installation steps
    2. See starting and testing the connector installation for more detailed instructions and common problems.
     

  7. When the status returns Passed for each queryset, your installation is complete
  8. Cloud customers must also verify connector connectivity to the frevvo Cloud Server.
  9. Follow the Connector Configuration Instructions with the detailed steps to integrate the connector with your database.

...

The connector relies on the JDBC API. You can use any relational database as long as you must have a JDBC driver for that your database. Refer to Supported Platforms for the list of databases certified by frevvo.

Warning

You MUST use a JDBC4 type driver, version 5.1.26 or later.

...

Info
  • You MUST copy the MS SQL (sqljdbc.jar) to the <frevvo-home>/tomcat/lib directory when running the connector in the frevvo-tomcat bundle AND using MS SQL as your external database
  • The jTDS driver requires an adidtional property, Refer to Datasource Definition Datasource  Examples  for information
  • It is also appropriate to You can copy the driver into any location that is in the CLASSPATH of your servlet container. In a the tomcat installation another . Another location would be <CATALINA_HOME>/lib 

DB Connector Quick Demo

The BIRT (ClassicModels) and myStore querySets are preloaded with in-memory Derby databases and test data.  This make it very easy to try out the connector.  No configuration is necessary.
