Hello,

Having been googling for hours, I realize that users can use either xml file(orm.xml, I suppose?) or annotations in JPA, or both of them at the same time. I'm i correct?
So, My project use the second-level cache, which is not in the JPA specification. And I use annotations like:
@org.hibernate.annotations.Cache(usage =
org.hibernate.annotations.CacheConcurrencyStrategy.READ_WRITE
)
for each entities.
However, I guess that the annotation above doesn't belongs to be JPA annotation, therefore, I don't know if there is anything equivalent in orm.xml? I have had a look at the xml schema of orm.xml, and there is not such hibernate element permitted in the schema.

If I can't do the second-level cache config in the orm.xml, is there any way other than in the annotation? The reason that I don't want to do it the annotation is because I have two applications, one use READ_WRITE concurrency strategy and another use READ_ONLY concurrency strategy.

Thanks in advance!!!
