Jadice uses dss to validate signed documents. The following jadice module can be integrated for this purpose:

Either add this module to your pom.xml or simply clone the project, adjust it for your needs and build via Apache Maven. Execute mvn install in the project's root folder (where the pom.xml is placed). This should result in a JAR file that will be placed in target folder under project's root folder. Include this JAR in your application's classpath and you will be able to use the included font resources.
