fax4j

fax4j is a reliable and easy-to-use fax library designed to enable Java applications to invoke fax actions.

The fax4j library enables integration with fax services via many different SPI (service provider interface) implementations.

Currently fax4j supports the following implementations: · Windows native fax API (requires windows fax/tapi component installed) · Windows COM fax API (via VBS called from the Java layer, requires windows fax / tapi component installed) · Email (via email servers that enable to send fax message based on incoming email messages) including built-in support for many of the leading vendors. · HTTP · External Processes · HylaFax (via gnu-hylafax library)

In addition the fax4j library also provides the fax bridge API which is a context specific faxing API.  The fax bridge enables to transform emails servers, web servers and more into an online fax service.
