On deploying EJB application on Weblogic : 12.2.1 , I am facing the exception :
"weblogic.management.DeploymentException: java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode"
I have the below configuration in persistence.xml to specify persistence provider
<persistence-unit name="entityManager">
<!-- Use Hibernate persistency -->
<provider>org.hibernate.ejb.HibernatePersistence</provider>
and below in weblogic-application.xml
<prefer-application-packages>
<package-name>antlr.*</package-name>
<package-name>javax.persistence.*</package-name>
Before this exception I was facing the exception "Error instantiating Persistence Provider class java.lang.ClassNotFoundException: org.hibernate.ejb.HibernatePersistence" which got resolved from
and since then I am facing this exception
I have provided below jars in the WL_DOMAIN/lib :-
dom4j
Also have provided in the classpath in below files as follows in WL_DOMAIN ---setDomainEnv.cmd
set EXT_PRE_CLASSPATH=C:\Projects\GMPP-CBOSS\MFSS\MFSS\lib\hibernate\slf4j- api.jar;C:\Projects\GMPP-CBOSS\MFSS\MFSS\lib\hibernate\hibernate-jpa-api.jar
---TrivEnv.cmd
set CLASSPATH=C:\oracle\Middleware2\modules\javax.persistence_1.0.0.0_1-0- 2.jar;C:\oracle\Middleware2\modules\com.oracle.jpa2support_1.0.0.0_2- 1.jar;%CLASSPATH%
----commonEnv.cmd -----oracle_common/common/bin

It may be possible that javax.persistence_1.0.0.0_2-0-0.jar was added at the beginning and also at the end of server classpath (in DOMAIN_HOME/lib dir).
As a result of this, two versions of the same jar in the same server classpath cause inconsistencies.
SOLUTION Remove javax.persistence_1.0.0.0_2-0-0.jar from the DOMAIN_HOME/lib dir.
