I am facing a strange error with weblogic 12c when deploying a web application with entities.
I ma using hibernate 3 as a JPA provider.
The error I am getting is
Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named
'ssv6PU' must be of type [javax.persistence.EntityManagerFactory], but was actually of
type [weblogic.jdbc.common.internal.RmiDataSource]
My bean is declared as

<jee:jndi-lookup id="ssv6PU" jndi-name="jdbc/ssv6DataSource" />

and the persistence unit as:

</persistence-unit>
what is strange is this works fine in MySQL 5,
is there some configuration I am missing? I think it is a matter of the driver. The Data source in the weblogic server is using the Oracle Thin driver for application continuity for 11.2.0.3 database version.

I have same database schema database_1 and database_2 and want to configuration of these two database(database schema is same) and decide run time which database is use.
My persistence.xml is as below:
<persistence-unit name="first" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.model.AboutUs</class>
<class>com.model.AccessCards</class>
<properties>
<property name="hibernate.dialect" value="com.util.customMySQLDialect" />
<property name="hibernate.hbm2ddl.auto" value="none" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" />
<property name="hibernate.jdbc.batch_size" value="20"/>
<property name="hibernate.cache.use_query_cache" value="true"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
</properties>
</persistence-unit>
Persistence name second configure here as below :
<persistence-unit name="second" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.model.AboutUs</class>
<class>com.model.AccessCards</class>
<properties>
<property name="hibernate.dialect" value="com.util.customMySQLDialect" />
<property name="hibernate.hbm2ddl.auto" value="none" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" />
<property name="hibernate.jdbc.batch_size" value="20"/>
<property name="hibernate.cache.use_query_cache" value="true"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
</properties>
</persistence-unit>
Both persistence units load same classes .
and now my database-configure.xml as where i configure persistence unit with data source. as below first persistence unit name configare with datasource name datasource as :
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="first" />
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${datasource.driverClassName}" />
<property name="jdbcUrl" value="${datasource.url}" />
<property name="user" value="${datasource.username}" />
<property name="password" value="${datasource.password}" />
<property name="acquireIncrement" value="1" />
<property name="acquireRetryAttempts" value="1" />
<property name="maxIdleTime" value="300" />
<property name="maxPoolSize" value="20" />
<property name="minPoolSize" value="3" />
<property name="maxStatements" value="300" />
<property name="testConnectionOnCheckin" value="true" />
</bean>
Now this code for configure second persistence unit name with data source name datasource5 as below :
<bean id="transactionManager5" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory5" />
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource5" />
<property name="persistenceUnitName" value="second" />
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
</bean>
<bean id="dataSource5" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="${datasource.driverClassName}" />
<property name="jdbcUrl" value="${datasource5.url}" />
<property name="user" value="${datasource5.username}" />
<property name="password" value="${datasource5.password}" />
<property name="acquireIncrement" value="1" />
<property name="acquireRetryAttempts" value="1" />
<property name="maxIdleTime" value="300" />
<property name="maxPoolSize" value="20" />
<property name="minPoolSize" value="3" />
<property name="maxStatements" value="300" />
<property name="testConnectionOnCheckin" value="true" />
</bean>
Now i use entity manager for save data in database and i am using mysql database . I got entity manager with persistence unit name first and second .
#PersistenceContext(unitName="first")
private EntityManager entityManager;
#PersistenceContext(unitName="second")
private EntityManager entityManager2;
Now entity manager save data in database using persist( object) method successfully .
entityManager.persist(project);
and entityManager2 save data in database using persist( object ) method successfully (No Exception here). But data does not store in database datbase_2 .
entityManager2.persist(project);
If I change the order of persistence unit first and second in persistence.xml then entityManager2 save data in database and entitymanager does not save data in database .
Any one have idea how i can make multiple entitymanager for same database schema .
There are a few limitations:
#Transactional corresponds to single TransactionManager.
JpaTransactionManager corresponds to single EntityManager(Factory).
Thus use separate methods with #Transactional annotation for each transaction manager:
#Transactional(transactionManager = "tmBeanName")
After that entity managers will work fine.
Also, some workaround exists to break the second limitation (DO NOT USE IT in this case):
It is possible to use single JtaTransactionManager instead of several JpaTransactionManager: distributed transaction will cover both entity managers and they will work fine too.
I want keep 2 datasources for 2 different databases (both are mysql) like below :
<bean id="jpaVendorAdapter"
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
<property name="generateDdl" value="true" />
<property name="database" value="MYSQL" />
</bean>
<bean id="dataSource-A"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url-A}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<bean id="entityManagerFactory-A"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource-A" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<!-- spring based scanning for entity classes -->
<property name="packagesToScan" value="com.package-A" />
</bean>
<bean id="dataSource-B"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url-B}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<bean id="entityManagerFactory-B"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource-B" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<!-- spring based scanning for entity classes -->
<property name="packagesToScan" value="com.package-B" />
</bean>
Now when i do simply this, beanInitializer gives error that entityManagerFactory is not found.
How can i have multiple entityManagerFactory, for multiple data base and what is best way to do in xml.
I googled quite a lot, but none is able to solve my problem.
It works well if i define only one entityManagerFactory, I am just stuck to have miltiple entityManagerFactory in same application context.
Below is the example for keeping multiple persistence unit for different type of database. Similarly 2 unit can be kept for both of your sql databases.

I am using the following persistence configuration with jpa2 (eclipseLink), spring 4.0.2, hibernate 4.3. Somehow the query result is always cached i.e. when I change the database in another application (e.g. direct sql) by inserting a new row, the new row is not returned here unless i restart the server (tomcat7 here). Am I missing anything here? thanks a lot!

I've managed to configure JPA with multiple datasources, but I get the following error when bringing up my server (Websphere liberty):

The application deploys correctly if all the DAO are declared in the same database, but it fails if I move any of them to a second database. Is it possible to used JPA bags (OneToOne, ManyToOne, ManyToMany) with multiple data sources?

I know its too late, but I had the same probleme.
I'm working on Oracle database, the same database with two schemas (users)
My solution was to give the first user access to all tables in the second user schema.
After that, on JPA Entity annotation, precise the schema for each entity.
This way, hibernate generate SQL queries with schema :
select field1, field2 from USER1.Table1 INNER JOIN USER2.TABLE2 ON .....
It work this way because user1 have access to user2 tables with a grant, but the two schemas must be in the same database, otherwise you have to create a dblink and a synonym.
Is there any way to persist cached objects in infinispan Cached store to a relational database Table?Iwas trying to do it as a Cacheloader.

From This keys and values are store in ISPN_STRING_TABLE_TEST_STORE where <namedCache name="TEST_STORE">. it saves keys in ID column and Values in DATA_COLUMN as a Blob.I want to Put this Blob Contain data into a relational database(Not as Object).As a example when I put a Employee object in Cache it should put database table as a Employee table with emplyee properties as a fields in That table.(Emp Name,Age.. etc).Is there a way to Do this?
There's an example in Infinispan Data Grid Platform Book which describes how to configure a JdbcStringBasedCacheStore using MySQL as relational database. In this example a Data source is used in the Connection URL, however it shouldn't be difficult to adapt it to your needs.Hope it helps.
