Subject Re: Is it possible to property placeholders in blueprint configuration file
Date Mon, 12 Apr 2010 14:37:23 GMT

org.apache.aries.blueprint.sample in our trunk demonstrated this
capability where the sample sets the property key.b to -1 and have the
property value injected to the bean called foo.
