Annotation x Local Session FactoryBean

[csantos]

Hello,

I'm changing an existing working webapplication to use Annotation Session FactoryBean instead of Local Session FactoryBean.
When i try to compile and run the existent tests, which worked before my changes, i get this Error:

Error creating bean with name 'sessionFactory' defined in class path resource [spring/persistence.spring.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.cfg.AnnotationConfiguration

I use maven to declare my dependencies, then i think i have already all necessary jar files.

The SessionFactory was declared as:

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotati on.AnnotationSessionFactoryBean">
<property name="annotatedClasses">
<list>
<value>....</value>
<value>....</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${database.dialect}</prop>
<prop key="hibernate.cache.provider_class">
org.hibernate.cache.EhCacheProvider
</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
</props>
<property name="dataSource" ref="dataSource" />
</bean>

Does anyone has an idea how to solve this problem?
thanks in advance,

I am also having the same issue. I am getting the "Could not initialize class org.hibernate.cfg.AnnotationConfiguration" error. Here is how my xml configuration for AnnotationSessionFactoryBean looks-

<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotati on.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.search.default.indexBase">./lucene/indexes</prop>
<prop key="hibernate.search.default.directory_provider"> org.hibernate.search.store.FSDirectoryProvider</prop>
</props>
</property>

<property name="annotatedClasses">
<list>
<value>demo.myproduct.SearchBean</value>
</list>
</property>

<property name="annotatedPackages">
<list>
<value>demo.myproduct</value>
</list>
</property>

</bean>

NoClassDefFoundError - means that there is not required library in classpath.
Do you have hibernate-annotations.jar in classpath?

[cooljava]

Andrei, I have verified that the hibernate-annotations.jar is there in the classpath. I am still getting this error. I am using maven and this is how the classpath looks-

<classpathentry kind="var" path="M2_REPO/org/springframework/spring/2.5.4/spring-2.5.4.jar" sourcepath="M2_REPO/org/springframework/spring/2.5.4/spring-2.5.4-sources.jar"/>
<classpathentry kind="var" path="M2_REPO/org/hibernate/hibernate/3.2.4.ga/hibernate-3.2.4.ga.jar"/>
<classpathentry kind="var" path="M2_REPO/org/hibernate/hibernate-annotations/3.4.0.GA/hibernate-annotations-3.4.0.GA.jar"/>

Can you check whether jar really is deployed?
tomcat\webapps\app\WEB-INF\lib

Eclipse has "Java EE Module Dependencies" feature. jar can be in classpath but won't be deployed.

And can you show full exception stack trace?

[cooljava]

I can see the jar files in tomcat deployment folder, so that probably is not a problem. Here is the stack trace-

Probably issue with hibernate library:

<classpathentry kind="var" path="M2_REPO/org/hibernate/hibernate/3.2.4.ga/hibernate-3.2.4.ga.jar"/>

hibernate-annotations declare dependency on hibernate-core 3.3.0.SP1
http://repository.jboss.org/maven2/o...s-3.4.0.GA.pom


I have tried to instantiate AnnotationConfiguration as BeanUtils does. And it is created successfully with libraries in classpath:

dom4j-1.6.1.jar
hibernate-annotations-3.4.0.GA.jar
hibernate-core-3.3.1.GA.jar
hibernate-commons-annotations-3.1.0.GA.jar
log4j-1.2.15.jar
slf4j-api-1.5.6.jar
slf4j-log4j12-1.5.6.jar

public class A {
	public static void main(String[] args) throws Exception {
		instantiateClass(org.hibernate.cfg.AnnotationConfiguration.class);
	}

	public static Object instantiateClass(Class clazz) throws Exception {
			return instantiateClass(clazz.getDeclaredConstructor((Class[]) null), null);
	}

	public static Object instantiateClass(Constructor ctor, Object[] args) throws Exception {
			ctor.setAccessible(true);
			return ctor.newInstance(args);
	}
}

Thanks Andrei,

It was an issue with missing entries in classpath. Once I downloaded missing jars and defined classpath correctly, everything worked as expected.

A good lesson too - always verify against the dependency POM to make sure everything is in place.

Thanks again!

I also get this exception when I run a test in a Spring project which used to use an Ant build but which I am now trying to use Maven.

etc.

I can see the class in the hibernate-annotations-3.4.0.GA.jar file, and I assume it is in the classpath since it is listed in the project's pom.xml.

Below is the pom.xml for my project. Can anyone see what I'm missing? The build (compile) works fine, but running the tests from within Eclipse, NetBeans, or Maven at the command line gives me the above error.

The tests were running fine before, but now this exception is killing all of them. Does anyone have any suggestions on where to look or what to try next? Thanks in advance for any ideas, I'm stumped.

Make sure you have following in classpath -

dom4j-1.6.1.jar
hibernate-annotations-3.4.0.GA.jar
hibernate-core-3.3.1.GA.jar
hibernate-commons-annotations-3.1.0.GA.jar
log4j-1.2.15.jar
slf4j-api-1.5.6.jar
slf4j-log4j12-1.5.6.jar

I had the same issue, but after correcting classpath for above mentioned entries I was able to resolve this.
