Good Day all ,
I am having this problem since many days now , I was able to successfully deploy JPA2.0 appliaction on weblogic 10.3.3 , the application can run select queries using JPA. But when I try to run a create or update information on the same table I get below exception
[code]
java.lang.ClassCastException: org.eclipse.persistence.jpa.PersistenceProvider cannot be cast to javax.persistence.spi.PersistenceProvider
[/code]
This is very strange because in my persistence.xml I have provided hibernate as JPA provider , the persistence unit defined is like below
[code]
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<!--
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
-->
<property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>
<!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
<property name="hibernate.hbm2ddl.auto" value="validate"/>
<property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
<property name="hibernate.connection.charSet" value="UTF-8"/>
<!-- Uncomment the following two properties for JBoss only -->
<!-- property name="hibernate.validator.apply_to_ddl" value="false" /-->
<!-- property name="hibernate.validator.autoregister_listeners" value="false" /-->
</properties>
</persistence-unit>
[/code]
And I have also provided the package level preferences in my weblogic.xml , below is my weblogic.xml file. As you can see I have explicitly told weblogic to prefer web app packages still it’s trying to load org.eclipse.persistence.jpa.PersistenceProvider instead of a persistenceProvider from hibernate jar.Please help me out here I am stuck at this point

I have asked the same question on below two forums in search for quick help.
https://forums.oracle.com/forums/thread.jspa?threadID=2474374&stqc=true
https://www.coderanch.com/t/599976/BEA-Weblogic/Weblogic-load-PersistenceProvider-wrong-jar
I finally figured a workaround for this problem , and now JPA2.0 application is running fine on Weblogic10.3.3 server.
I found out that the problem was actully relted to hibernate validator , In my JPA method code I had a “@Valid” annotation along with the object I was getting , I was trying to use hibernate validator to validate the object before persisting it , there I was getting all these exceptions.
To get my application running on server I had to remove those @valid annotations from my JPA code and now everything is working fine. But now I am relying on page level validation which in my case is good enough.
However the ideal solution would be to find a compatable hibernat validator jar and keep the @valid annotations in your project for the sake of better validation.
For now this solution is working for me , ASA I get time I will try to find the hibernate validator jar which can work with this version on server we have and will love to have server side validation as well.
I hope this workaround will save some days of someone out there :).
