The Database Connector is a web application that allows you to easily integrate your Live Forms forms and flows with your external database. The connector is included in the Live Forms tomcat bundle. A Standalone Bundle is also available.

The Database Connector may function with other servlets and databases only the ones listed on the Supported Platforms page have been certified by frevvo

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

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

Installation Steps

Throughout this documentation we are using the  tomcat bundle as the installation location for the database connector. This documentation assumes that the  tomcat bundle is installed in c:\frevvo. We'll refer to this directory below as <frevvo-home>.

If you have already downloaded the tomcat bundle for  In-house then you already have the database connector. It is located in the unpacked  tomcat bundle in <frevvo-home>\frevvo\ext\connectors and is named database.zip. 

Follow these steps to install the connector:

1) Unpack the database.zip file to a temporary location of your choice: e.g. c:\tmp. This will create a folder c:\tmp\database. We'll refer to this directory below as <db-tmp>

2) Copy <db-tmp>\database.war to <frevvo-home>\tomcat\webapps

  • If  is running this will automatically expand database.war into a <frevvo-home>\webapps\database sub folder

3)  If  is not running, start : Double click <frevvo-home>\start-frevvo

  • This will start  and it will automatically expand database.war into a <frevvo-home>\webapps\database sub folder

4)  Test the connector installation by copying this Url directly into your browser:

If the 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.
  3. If you cannot get the database connector working please see Getting Help to contact  support.

Follow these steps to configure the connector:

If the connector test above was successful you are now ready to configure the database connector to work with your own database.

1)   Copy the JDBC driver appropriate for your database into <frevvo-home>\tomcat\webapps\database\WEB-INF\lib

  • The database connector contains pre-installed drivers for the most popular databases. So you may be able to skip this step. See Install a JDBC driver below

2)    If you did have to copy a JDBC driver into lib you must then Restart frevvo, Double click <frevvo-home>\stop-frevvo. Wait until  stops. Then Double click <frevvo-home>\start-frevvo

3)    Configure your database connector Data Source by editing <frevvo-home>\tomcat\webapps\database\WEB-INF\etc\configuration.xml

4)    Define SQL Statements to read/write to your database by editing <frevvo-home>\tomcat\webapps\database\WEB-INF\etc\configuration.xml.

We recommend that you do not leave your database configuration.xml file in its default locations. See configuration file location below.

Install a JDBC driver

The connector relies on the JDBC API. You can use any relational database as long as you have a JDBC driver for that database. The database connector download database.zip comes with several pre-installed drivers.

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

The  download package comes with several pre-installed drivers. Look in <frevvo-home>/tomcat/lib and you will see (among other jar files) the following pre-installed driver jar files:

  • hsqldb-2.2.4.jar - HSQLDB driver
  • jtds-1.2.5.jar - SQL Server driver
  • postgresql-9.0-801.jdbc4.jar - Postgress driver

If you don't find what you need pre-installed you will need to locate a driver compatible to your database. Usually you can download your driver from the internet. Try one of these locations

Once you have the driver you need, copy it to <frevvo-home>/tomcat/lib. 

It is also appropriate to copy the driver into any location that is in the CLASSPATH of your tomcat installation. Another location would be <CATALINA_HOME>/lib.

Previous Pre-Installed Driver Versions

Previous versions of  include these drivers:

  • hsqldb-1.8.0.7.jar - HSQLDB jdbc driver
  • com.microsoft.sqlserver.jdbc-1.1.3.jar - SQL Server driver
  • jtds-1.2.5.jar - SQL Server driver
  • org.objectweb.rmijdbc-1.0.0.jar - Access driver (also can be used for SQL Server)

If you don't find what you need pre-installed you will need to locate a driver compatible to your database. Usually you can download your driver from the internet. Try one of these locations
