I'm having a little trouble getting the interpolation to work, I have a
properties file with contents similar to:
---
file.resource.loader.path = ${VELOCITY_TEMPLATE_HOME}
---
Where VELOCITY_TEMPLATE_HOME is an environmental variable that I need to
get expanded , how would I do this ?
Thanks,
Charlie

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);
