Is there any way to avoid using hardcoded URLs in the ChangeSet resource XML file? I'd like to be able to parameterize that bit of data and substitute the actual value at runtime. For example, something like this would be nice: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd'> <add> <resource source='${rules.url}' type='DRL' /> </add> </change-set> ${rules.url} would be read from a resource bundle (i.e. property file) at runtime. Is there some extension point that I can use to implement this behavior? ----------------------------------------- This e-mail and any attachments may contain CONFIDENTIAL information, including PROTECTED HEALTH INFORMATION.
