titleOverview

 was designed to integrate with your back end systems. The form server is built using industry standard such as XSD, XML and Restlet. This chapter covers the built-in connectors as well as how to add your own connectors to the form server.

Note
  • frevvo Connectors are an Add on feature with additional costs.
  • frevvo only supports/certifies frevvo connectors running in the Apache Tomcat container. Refer to our Supported Platforms for the list of Application Servers and databases supported/certified by frevvo.

Integrating Connectors with Cloud Server

Excerpt

Connectors are most commonly installed behind your firewall where they can access (connect) to your back end systems in order to read/write data. If you use the frevvo Cloud hosted server you must ensure that your Connectors are accessible from our servers. This is done by opening up one of the following ports on your firewall:

Info

We recommend that you use https and not http. Https is a secure channel.

  • HTTP Ports: 80, 8082 or 19080
  • HTTPs Ports: 443, 8443 or 19443

For customers that use firewall white-listing, also make sure the frevvo cloud outgoing server IP 54.86.85.105 (host outgoing.frevvo.com) is added to the list.

Connector Security

 connectors installed on-premise should only be accessible to the frevvo server i.e. http://localhost:8983/, and should not be remotely accessible. Most customers don’t allow external http access to a server (only https). Since the connector(s) is not exposed over https, remote code execution vulnerability can be mitigated (a remote attacker cannot exploit this vulnerability as it is not exposed). Another option to enhance connector security is to block external access to port 8983, for example using firewall rules.
