Datanucleus XmlMetaDataEntityResolver - how do you disable XML entity resolving? #487

Closed minfrin closed 1 year ago

minfrin commented 1 year ago

By default, org.datanucleus.metadata.xml.XmlMetaDataEntityResolver.resolveEntity attempts to resolve XML entities over the internet.

How do you switch XML entity resolving off?

If you put an XSD in an XML file as a URL then you get internet-based validation ... which you could easily have avoided by specifying a STANDARD persistence.xml location as per the docs. Or look at datanucleus.metadata.xml.validate

BUT then an ISSUE TRACKER is not the place to ask questions, it is for ISSUES. That is what Gitter / groups.io are for
