Peter,

I realize that this is probably not the answer you're looking for. The relationship between generic-dao, Spring 3, and Hibernate will need to be reconciled eventually. This is more of a background message since I worked on the upgrades of both.

As of Spring 3, the HibernateDaoSupport / HibernateTemplate stuff is discouraged. Our usage of these is why we couldn't upgrade to Hibernate 4, since they are explicitly for Hibernate 3 and do not support 4.x (or at least I did not see any workaround/bridge). For years, Spring has recommended that you use the Hibernate API directly. The support classes were made before Hibernate 3 so it was easier to integrate Hibernate and Spring transactions. I suppose they were successful, but Hibernate has done this natively, I think, since 3.0.

http://stackoverflow.com/questions/5104765/hibernatedaosupport-is-not-recommended-why
http://docs.spring.io/spring-framework/docs/3.2.x/javadoc-api/org/springframework/orm/hibernate3/HibernateTemplate.html

However, you should still be able to use the org.springframework.orm.hibernate3.support package while we are using Hibernate 3. I'm quite sure that other tools using generic-dao have come over without problems.

While typing this up, it looks like you have found the answer. Including spring-orm should make everything available.

Thanks,
-Noah

I don't think we have changed the stuff in generic-dao (certainly by
removing things) in awhile. What are you trying to do? Can you point
to some code?

Hi Aaron,



Are there any changes for generic-dao for Spring 3.2.3.release version
(Sakai 10)?



The getHibernateTemplate() method is missing for HibernateGeneralGenericDao





Any advice?



Thanks,

Peter

I almost get Sakai  10 environment set up.



I have just noticed that after updated to Spring 3.2.3.relesae, the
getHibernateTemplate() method is missing in generic-dao.



Have you guy already resolved this issue?



Thanks,

Peter

Steve--a request.  The spring dependencies need updating to bring them up to
3.2.3-RELEASE.  Can you deal with that?  Otherwise, I'll work on fixing
them.



Now back to signup to get rid of the ecs deploy pom.



Signup is also being deployed to the sonatype repo.
