Recommend an ORM for Java applications?

Question

Java

I know about hibernate and datanucleus (I used the latter). But I would like to get more up-to-date information, because. already done a lot.
For example, interested in ObjectDB, OpenJPA (ObjectDB is 2 in one, takes first place almost everywhere on the site www.jpab.org ).
I would be grateful if someone shares their experience.

Answer 1

There is little experience - about six months with OpenJPA, but 2 years ago. Then it was raw, there were a lot of bugs, now I don’t know.

Answer 2

Enhanced Hibernate and standard JDBC features
with
spring jdbc-templates
spring ORM package.
there are a lot of useful things...

Answer 3

ObjectDB looks interesting, but the lack of an external cache, like in hibernate, upsets. For example, in EhCache 2.5 it will be possible to specify the amount of memory for the cache and forget about all other settings. And also enable EhCache BigMemory, on large cache volumes. Or connect a smart BoneCP pool.
The site has been registered since 2003, but for some reason no one has heard of ObjectDB, although I once rummaged through a bunch of frameworks, but I didn’t even come across a mention of this ORM.

Answer 4

In general, I did not see worthwhile replacements for hibernate. I think it makes sense to look for them in lighter ORMs that are closer to SQL, like the ibatis example, but in 2008 I didn’t really like it. Maybe it's better there now.
PS I'm watching ibatis now, but for some reason it's restricted from apache.org

Answer 5

I only like EclipseLink and OpenJPA.
