Hibernate 3 with Wildfly 9

[kamal7725]

Hi,

I am migrating from JBoss 6 to Wildfly 9.

My application is using Hibernate3 but Wildfly comes with Hibernate4, and this causing antlr conflict while deployment of the application. I searched the net and find out the way to use Hibernate 3. In my persistence file I added a line <property name="jboss.as.jpa.providerModule" value="org.hibernate:3"></property> and then again started the deployment but failed. Now it is complaining about the "Failed to define class org.jboss.as.jpa.hibernate3.JBossAppServerJtaPlatform in Module "org.jboss.as.jpa.hibernate:3". Can anybody please help me sort out this problem.

Thanks

Hibernate 3 is not tested for compatibility with wildfly 9..It  recommends using the fully supported (bundled) Hibernate 4 release with wildfly 9 as it has been tested for compatibility with wildfly 9. You need to use right hibernate version which is shipped with wildfly release.

It happens due to multiple  version of hibernate libraries are present inside your system class path.

It is possible the application fails due to automatic inclusion of the built-in integration with Hibernate that is part of wildfly

It may be possible to exclude the supported Hibernate libraries by excluding the "org.hibernate module". see the below document how to Exclude  Dependency:
