The Database Connector is a web application that allows you to easily integrate your frevvo forms and workflows with your external database. The connector can be added to your frevvo 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, database and On Premise customers can choose to:

  • install the Database Connector in your frevvo 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-tomcatBundleInstructionstomcat 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 frevvo server installation. Follow the StandaloneBundleInstructions Standalone Bundle Instructions

The Database Connector requires a JDBC driver for your database. Some pre-installed drivers are included with the connector. See InstallaJDBCdriver 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.

These instructions assume that your frevvo-tomcat bundle is already installed and running successfully.

  1. Stop your frevvo server.
  2. Download Database Connector war file that is compatible with the version of frevvo that you are running to <frevvo-home>\tomcat\webapps.
  3. Rename the downloaded file to database.war
  4. InstallaJDBCDriverInstall a JDBC Driver

  5. Start your frevvo server

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

  7. If the status returns failures or disabled:

    1. Review the previous installation steps.

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

  8. When the status returns Passed for each queryset, your installation is complete
  9. Follow the Connector Configuration Instructions with the detailed steps to integrate the connector with your database.

...

  1. Install the Driver
    1. If your database uses a preinstalled drive, you can skip this step. The preinstalled drivers are:
      1. MS SQL driver - This is embedded in the database.war file with the standalone bundle; however, however it is not embedded in the frevvo-tomcat bundle.
      2. DERBY driver
    2. If your database driver is not preinstalled, you will have to locate a compatible driver from the internet. Try these locations.
      1. Oracle
      2. MySQL
  2. Locate the driver (i.e. mysql-connector-java-<version>-bin.jar or ojdbc6.jar) among the files that were installed. For example, on the location may be: Windows C:\Program Files (x86)\MySQL\MySQL Connector J\mysql-connector-java-8.0.19-bin.jar.
  3. Copy your driver to
    • Tomcat Bundle <frevvo-home>/tomcat/lib, or 
    • Standalone Bundle <db-home>\database-connector-2.5.x\lib 

...

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

Follow the steps below to deploy the connector in the the frevvo-tomcat bundle and you can get started very quickly

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 latest frevvo-tomcat bundle from the frevvo website.

  2. Download the Database Connector war file. Rename it to database.war.

  3. Extract the tomcat bundle zipfile to a location of your choice. We will refer to this directory as <frevvo-home>.

  4. Copy database.war to <frevvo-home>\tomcat\webapps.

  5. Start the Insight server, then start frevvo.

  6. Test the connector installation by copying this URL directly into your browser:
    http://localhost:8082/database/status
    After performing these steps you will have: successfully installed the frevvo database connector and retrieved data from the built-in test database
  7. Log into frevvo as the superuser (admin@d, admin). Create a tenant.
  8. Create a designer user in the tenant
  9. Download the Database Connector Project, then upload it to your designer user. This project includes some example forms that demonstrate the power of the Database Connector using built-in databases.
