Hibernate listerner : Could not instantiate requested listener

layoup Dec 18, 2019 7:58 AM

Hi,

I try to migrate applications from an Glassfish 3.1.2.2 to an Wildfly 18 server.

Applications are quite old and use hibernate 3.6.8 Final.

I read that Wildfly come with different versions of hibernate in modules. I decided to use the most recent available version package with Wildfly 18, 5.3.13 Final.

So I tried to migrate one of my applications. I modified pom.xml of this application to have an dependancie to hibernate 5.3.13.Final with provided scope.

I modified my persistence.xml and fix some classes. Now my project compile fine.

Here is my perrsistence.xml

<?xml version="1.0" encoding="UTF-8"?>

Nevertheless when I tried to deploy my project, deployement stops with this message :

I think that is an classloader issue. Hibernate can't reached my application classes because of classloader hierarchy.

Someone clould me explain how to deals with this situation ?

To solve this issue, I am trying to install an wildfly module with application's hibernate listener.

My module configuration is :

<?xml version="1.0" encoding="UTF-8"?>


<module name="fr.onf.socle.hibernate.listener" xmlns="urn:jboss:module:1.5">


    <resources>
        <resource-root path="hibernate-listener-0.0.1-SNAPSHOT.jar"/>
    </resources>


    <dependencies>
        <module name="org.hibernate" slot="5.3" />
    </dependencies>
</module>

I put this module.xml and jar with my 2 listeners in directory $JBOSS_HOME/modules/fr/onf/socle/hibernate/listener/main

In my application I created an jboss-deployment-structure with this content :

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="fr.onf.socle.hibernate.listener" />            
        </dependencies>
    </deployment>
</jboss-deployment-structure>

Sadly, it doesn't work but I am sur that is a good approach.

What is your opinion ?

Do you see any error in the logs starting with *HHH* ? If yes, can you please attach the logs ?

No log with level Error starting with HHH*. Only Warn (about generator duplicate name and composite-id without equals and hashCode) and Info.

Error is always :

Thanks a lot for your help.

What I don't understand is how to give to Hibernate acces to my project's classes.

I try to install an module with an jar including all my hibernate listener but it doesn't work.

How to be sure that a module is effectively load on deployment ?

How to be sure that my module is accessible by Hibernate module ?

Best regards

Hi,

My understanding is that hibernate module doesn't find you listeners.
Could you try the following: modify hibernate module and add your module into dependencies inside hibernate, just to check it

Thanks,
Vlad

Hello,
Already tried but Wildfly doesn't start.
I will try another time because of I perhaps made a mistake first time.
Thanks for your reply

First time, I installed my custom module by hand but I made an mistake. I deleted what I did and use jboss-cli to create my custom module.
Now when I add my module as an dependency of hibernate module, wildfly start well but I have always an class not found for my listeners.
So only to try I removed my custom module from dependencies and added my jar as an resource root of wildfly's hibernate module.
It doesn't work !!!! Always an class not found.
I checked my jar and my two listeners are in.
I do not understand anything.

Hi,

If you can extract your custom module that contains listeners, I can try to play locally with it.

Thanks,
