Samply Common Config

This library offers utilities to find and deserialize configuration files depending on the operating system. It also offers configuration objects that have been created from XSD files with xjc.


The application must use a prefix, which defines the properties and environment variables that are used to find the requested file.

Use the FileFinderUtil to find a configuration file, e.g.

File file = FileFinderUtil.findFile("config.xml", "samply");

The FileFinderUtil will now search for the config.xml file in the following locations:

  • location defined by the Java property samply.confdir (defined at runtime with the -Dsamply.confdir argument)
  • location defined by the environment variable SAMPLY_CONFDIR (defined at runtime with SAMPLY_CONFDIR=)
  • user home directory (~/.config/samply/, e.g. home/paul/.config/samply on Linux, C:\Users\paul\.config\samply on Windows)
  • OS Specific location (e.g. /etc/samply/ for Linux, uses the location defined in the Registry HKEY_LOCAL_MACHINE/SOFTWARE/SAMPLY/ConfDir for Windows Systems)
  • the location defined by the fallback parameter, if there is one

You can also use the JAXBUtil to deserialize an XML file into an object. If possible you should use the ObjectFactory in the JAXBContext, e.g.

Postgresql sql = JAXBUtil.unmarshall(file, JAXBContext.newInstance(ObjectFactory.class), Postgresql.class);

This method will unmarshall the given file into a Postgresql instance.


Use maven to build the jar:

mvn clean package

Use it as a dependency:
