We have a project that uses Velocity, which uses ExtendedProperties,
which we want to extend to interpolate environmental variables and
system properties.
Does anyone have any objection / suggestion for this ? Is we write the
patch is this something that could be included ?
An alternative is to build a Configuration with Commons Configuration
that performs the interpolation you want, and then turn it into an
ExtendedProperties.
The code would look like this:
CompositeConfiguration config = new CompositeConfiguration();
config.addConfiguration(new SystemConfiguration());
config.addConfiguration(new EnvironmentConfiguration());
config.addConfiguration(new PropertiesConfiguration("conf.properties"));
ExtendedProperties props =
ConfigurationConverter.getExtendedProperties(config);
