[infinispan-dev] A tool for adjusting configuration

[Galder Zamarreño]

Before you start messing with XML itself, you might want to see what we do in Hibernate 2L.

We first load the XML configuration [1], and using the ConfigurationBuilderHolder we can swap cache configurations, we can tweak them...etc, and eventually we create a cache manager out of that.

>From the tweaked configuration, you could potentiallt chuck out XML. That's a better approach IMO than using XPath or similar tech.
