I want to make a test with HQL but the mapping tables is with Annotations.
Hibernate configuration file is in the /WEB-INF/spring-config-ws.xml :::>

When I run a list, I get that you do not find the hibernate cfg:
hibernate.cfg.xml not found
I just want to list a mapped class with annotations, but HQL
I feel my level of English is so low. Thank you
Make sure your hibernate.cfg.xml is inside src/main/resources, if the file is not there you need to specify the right location, so put it inside this folder that your problem will be solved.
Note that we don’t have to explicitly mention the mapping or configuration or properties
files, because the Hibernate runtime looks for default filenames, such as hibernate.
cfg.xml or hibernate.properties, in the classpath and loads them. If we have a nondefault
name, make sure you pass that as an argument—like configure("my-hibcfg.
xml"), for example.

We have an application where we have implemented Abstract Routing Data source feature in dealing multiple data bases of same type mysql (jdbc:mysql://127.0.0.1:3306/test, jdbc:mysql://127.0.0.1:3306/test2).
Now we are going with different database which is DB2. so i was unable to find any samples for this scenario using abstract routing datasource.
Can anyone give any directions ?
This is my code block:
i have defined 3 datasources itemDataSource, custDataSource, orderDb2DataSource in dao.xml .
how to configure the second session factory to the the transaction manager ?
<bean id="dataSource" class="com.test.DatabaseRoutingDataSource">
<property name="targetDataSources">
<map key-type="com.test.dao.DatabaseType">
<entry key="ITEM" value-ref="itemDataSource"/>
<entry key="CUSTOMER" value-ref="custDataSource"/>

I have successfully configured hibernate and I can run transactions but only from the psvm of the DAO class. I want to configure it with my spring app using the same configuration file i.e. hibernate.cfg.xml.
How can I do this? Most tutorials I've read simply neglect the hibernate configuration file.
You can add this code to you xml file to configure hibernate.

The hibernate.cfg.xml file is specified for the LocalEntityManagerFactoryBean, along with your DataSource
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath*:META-INF/hibernate.cfg.xml" />
<property name="dataSource" ref="dataSource" />
</bean>
Here you can find an example of a Spring XML configuration containing some Hibernate configuration
Technologies used:
Spring 3.2 (Java framework)
Hibernate 3.6 (ORM)
HSQLDB (embedded DB)
Current configuration in Spring is as follows:
<!-- Data-source -->
<jdbc:embedded-database id="dataSource" type="HSQL" />
<!-- Session Factory database -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="au.com.afgonline.pce.model" />
<!-- <property name="schemaUpdate" value="true" /> -->
<property name="hibernateProperties">
<props>
<!-- <prop key="hibernate.show_sql">true</prop> -->
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<!-- Transaction Manager -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- Hibernate Template -->
<bean id="hibernateTemplatePce" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
Where do we specify the folder location for HSQLDB to save the data back to the file system?
What is the difference between using datasource and using hibernateProperties. I want to use c3P0 with spring in my app. I found 2 ways to do so but I'm unable to understand the difference between the two
First:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
depends-on="dataSource">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="hibernate.use_sql_comments">false</prop>
</props>
</property>
<bean id="dataSource" destroy-method="close"
class="com.mchange.v2.c3p0.ComboPooledDataSource" >
<property name="maxPoolSize" value="10" />
<property name="numHelperThreads" value="5" />
</bean>
Second:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
>
<property name="hibernateProperties">
<props>
<property name="hibernate.c3p0.maxSize" value="100" />
<property name="hibernate.c3p0.numHelperThreads" value="5" />>
</props>
</property>
</bean>
The first you get a Spring managed datasource, which you can also use for a JdbcTemplate or other work.
The second you get a hibernate managed datasource which is not reusable by Spring.
I strongly suggest the first approach as it also makes it quite easy to replace your datasource for testing (by replacing it with an in-memory database) or to replace it with a JNDI lookup.
I want to rewrite my sessionFactory bean using the p-namespace. I understand how to reference general objects, but I've never dealt with lists, props, etc. How would I go about writing , and so on?
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
<value>/com/mysite/domain/Object.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
This is the code I have so far in p-namespace:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:mappingResources-list="/com/mysite/domain/Object.hbm.xml"
p:hibernateProperties-props=""/>
You cannot do this directly . You could use util:map though. Try
<util:map id="hibernateConfig" >
<entry key="hibernate.hbm2ddl.auto" value="update" />
<entry key="hibernate.show_sql" value="true" />
<!-- Other properties -->
</util:map>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:mappingResources-list="/com/mysite/domain/Object.hbm.xml"
p:hibernateProperties-ref ="hibernateConfig"/>
