I know this question has been asked a bunch of times, but none of the suggested solutions work for me.
I have an XML docuement that references a custom DTD:
<!DOCTYPE page_registry SYSTEM 'file:///opt/STT/system/core/docs/dtd/PageRegistry.dtd'>
IDEA tells me that this URI is not registered. So, I enter it into the Resources panel of the IDE Settings using these values:
However, IDEA still tells me that it is not registered.
Is there some other trick to getting this to work? I'm wondering if this has anything to do with the fact that my module is a Java module, not a Web or EJB module. Maybe URI registration doesn't work with Java modules?
Any help would be appreciated as I've been trying to figure this out for several weeks.
