An XSL-FO processor plug-in is used by process commands in (and more specifically element
processFO in ) to invoke a third-party XSL-FO processor. For example, an XSL-FO processor such as Apache FOP is used to convert to PDF the XSL-FO intermediate file created by the → → process command.
Like all plug-ins, an XSL-FO processor plug-in is not declared anywhere. It is dynamically discovered and loaded during the startup of XXE (more info in Section 1, “Dynamic discovery of add-ons” in ) provided that it complies with the following conventions:
The code of the XSL-FO processor plug-in must be contained in a JAR file having a name ending with "
This JAR file must contain a
META-INF/services/com.xmlmind.foprocessor.FOProcessor file containing the name of the class implementing interface
META-INF/services/com.xmlmind.foprocessor.FOProcessor which contains
If you plan to implement an XSL-FO processor plug-in and need an example showing how this can be done, please send an email to
