Hi,

I'm looking to upgrade my hibernate API to be aligned with 3.5.4-Final version.

Currently my pom.xml is pointing to:

Code:

        <dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate3</artifactId>
     <version>3.3.2.GA</version>
   </dependency>

My question is:

1. what is the difference between hibernate3 & hibernate-core jar?
2. In order to conduct this upgrade - do i need to replace hiberante3 jar ?

Thanks.

You should change to:

Code:

<dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate-core</artifactId>
     <version>3.5.4-Final</version>
</dependency>

hibernate3 is an obsolete artifact. After successful "mavenizesation" the artifact names are hibernate-core, hibernate-annotations, hibernate-entitymanager, ...

Hi,
after changing the artifact to be hibernate-core - my server (Tomcat 6.0) isn't starting:

I get:

java.lang.ClassNotFoundException: org.hibernate.cache.EhCacheProvider

Please advice.

You need to also add

Code:

<dependency>
     <groupId>org.hibernate</groupId>
     <artifactId>hibernate-ehcache</artifactId>
     <version>3.5.4-Final</version>
</dependency>

If and which cache to use is puggable. You have to explicitly specify your cache provider. Alternative choices are oscache, jbosscache, ...
I think in the hibernate3.jar artifacts ehcache was still included as some sort of default cache.

Thanks - it is ok now.

Should i expect run time errors or is it backwards compatible?

Wouldn't be able to tell out of the top of my head. I recommend you read the release logs.
It will of course also depend on which functionality you are using.
