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

Live Forms

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.
