I have a very weird problem.
Have an application using Hibernate and spring.I have an entitymanger defined which uses a JNDI lookup .It looks something like this
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="ConfigAPPPersist" />
<property name="jpaVendorAdapter">
<bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
<property name="generateDdl" value="false" />
<property name="databasePlatform"
value="org.hibernate.dialect.Oracle9Dialect" />
</bean>
</property>
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.WebSphereDataSourceAdapter">
<property name="targetDataSource">
<bean
class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/pmp" />
</bean>
</property>
</bean>
This application runs
fine in DEV.
But when we move to higher envs the team that deploys this application does it successfully initially but after a few restarts of the application the entitymanager starts giving this problem
Caused by: javax.persistence.PersistenceException: [PersistenceUnit: ConfigAPPPersist] Unable to build EntityManagerFactory

Caused by: org.hibernate.MappingException: **property mapping has wrong number of columns**: com.***.***.jpa.marketing.entity.MarketBrands.$performasure_j2eeInfo type: object
Now you would say this
is pretty obvious the entity MarketBrands
is incorrect. But its not it maps to the table just
fine. And the same code works on DEV.
Also the jndi cannot be incorrect since it deploys and works
fine initially but throws uo this error after a restart.
This
is weird and not very logical.
But if someone has faced this or has any idea on what might be causing this Please!! help
The persistence.xml for the persitence unit has very little
