Hello,
There's this use case in front of me that involves metadata of resources in a hierarchy (e.g. a filesystem). I was thinking of implementing this as follows:
* Create an XML document describing this hierarchy and the associated metadata.
* Use XPath to query for metadata for a given resource.
Can someone please advice on how safe and efficient is the use of a single document instance for concurrent XPath queries (in a J2EE environment). Is it safe and efficient to share a single instance across the application threads (again, for readonly access)?
Many thanks in advance,
Manos
