R – Spring + Hibernate bean declaration error

hibernatespring

  <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
  <list>
    <value>product.hbm.xml</value>
  </list>
</property>
<property name="hibernateProperties">
  <value>
    hibernate.dialect=org.hibernate.dialect.HSQLDialect
  </value>
</property>

I have this configuration in my applicationContext.xml file

However I get this error when I try to run my application:

Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'sessionFactory' defined in
ServletContext resource [/WEB-INF/applicationContext.xml]
Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Could not
instantiate bean class
[org.springframework.orm.hibernate3.LocalSessionFactoryBean]:
Constructor threw exception; nested exception is
java.lang.NoClassDefFoundError: org/dom4j/DocumentException

So it seems like it's not recognizing the class LocalSessionFactoryBean. However I when type, import org.springframework.orm.hibernate3.LocalSessionFactoryBean;, eclipse doesn't complain.

Does anybody have an idea why this is happening?

I believe the key is this line:

nested exception is java.lang.NoClassDefFoundError:
org/dom4j/DocumentException

I would check the classpath to ensure that dom4j is there.

Java – What’s the difference between @Component, @Repository & @Service annotations in Spring

From Spring Documentation:

The @Repository annotation is a marker for any class that fulfils the role or stereotype of a repository (also known as Data Access Object or DAO). Among the uses of this marker is the automatic translation of exceptions, as described in Exception Translation.

Spring provides further stereotype annotations: @Component, @Service, and @Controller. @Component is a generic stereotype for any Spring-managed component. @Repository, @Service, and @Controller are specializations of @Component for more specific use cases (in the persistence, service, and presentation layers, respectively). Therefore, you can annotate your component classes with @Component, but, by annotating them with @Repository, @Service, or @Controller instead, your classes are more properly suited for processing by tools or associating with aspects.

For example, these stereotype annotations make ideal targets for pointcuts. @Repository, @Service, and @Controller can also carry additional semantics in future releases of the Spring Framework. Thus, if you are choosing between using @Component or @Service for your service layer, @Service is clearly the better choice. Similarly, as stated earlier, @Repository is already supported as a marker for automatic exception translation in your persistence layer.

Annotation	Meaning
`@Component`	generic stereotype for any Spring-managed component
`@Repository`	stereotype for persistence layer
`@Service`	stereotype for service layer
`@Controller`	stereotype for presentation layer (spring-mvc)

Java – Can’t initialize sessionFactory. Hibernate 3 in Spring

You are missing the dependency to hibernate.

Because the spring-orm artifact handles ORM using plain Hibernate, JPA, JDO and iBatis (and it hardly ever makes sense to use them all), all of these depenencies are marked as optional, which means that you have to reference the dependencies in your pom.xml. Here's how to reference the latest stable version of hibernate core:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>3.6.7.Final</version>
</dependency>
