How to @Inject values from a .properties file with CDI

How can i inject some values from a properties file? I have a .properties file with some keys and values, i would like to inject those to use on some classes, something like:

@Inject(file = "/WEB-INF/abc.properties",key ="path")
private String path;

So when i use the path it has the value from the properties file, instead of going thorough the entire process of reading the properties and getting the value.

While there has been active discussion about integrating configuration in CDI, the current status is that there won't be a standard Java configuration JSR anytime soon.

In the meantime, configuration integration is provided by third-parties like DeltaSpike, see http://deltaspike.apache.org/documentation/configuration.html so that it is possible to write:

@Inject
@ConfigProperty(name = "endpoint.poll.interval")
private Integer pollInterval;

That relies on the service loader meachanism to extend the configuration sourcing.

The Apache Tamaya project plans to have CDI integration as well.
