Re: [eclipselink-users] Problem with using xml and annatations
Hi Lukasz,

You could have your entities extends a MappedSuperclass and define a caching strategy there to be applied to all its subclasses.

Cheers,
Guy

wow, thanks! I've been starring at the exception for too long ...
by the way, is there an easier way to specify global expiry time than to add such configuration for each entity?

best regards
Lukasz

There is a mistake in the XML file listing the address class.  The XML uses a class called Addresss, which is different then the actual Address class.  Fix the spelling mistake and it should work.

Best regards,

hi,

I use annotations for my entities but would like to configure eclipselink caching expiry in xml so the entities can be reused with different cache settings.

But when I add eclipselink-orm.xml with this additional configuration I got "Entity name must be unique in a persistence unit." I tried various settings but it looks like I cannot force eclipselink to merge xml stuff with annotations (I have metadata-complete="false").

Can you offer any hint? (I tried versions from 2.3 to 2.5.1 but it behaves similarly) 

best regards
Lukasz
