I am currently migrating an older application from hbm mappings to annotations. I have read numerous places stating that it is possible to do this, including the hibernate docs. I am running into trouble when I try to reference an annotated class from an hbm mapped with a many-to-one relationship.
I am getting the following error complaining about the annotated class.
"nested exception is org.hibernate.MappingException: Association references unmapped class: ...cepis.domain.Note"
Is it possible to achieve what I want here, is there something very basic that I am missing (note like I said I have read numerous times that it is possible so a simple "yes it is possible" will not be of much help)?
My session factory is defined as follows ...
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
scope="singleton">
<property name="dataSource" ref="itc5DataSource" />
<property name="mappingResources">
<list>
<value>edu/uky/cepis/User.hbm.xml</value>...
</list>
</property>
<property name="annotatedClasses">
<list>
<value>edu.uky.cepis.domain.Note</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${itc5.dialect}</prop>
...
</props>
</property>
</bean>
Thank you so much for any help in advance!
have you tried setting _ hibernate.mapping.precedence_ to "class, hbm"?

I've been trying to wrap my head around this issue all day.
Currently our project has setup JPATransactionManager through a Spring Application Context to take care of our various session transactions with the use of #Transactional on all services that take care of persistence and deletions (DAO usage).
Changing over from Hibernate 3 to 5, we wanted to remove our use of a custom audit interceptor and move onto using Hibernate Envers. I have annotated all my classes properly and have the tables being created, but once it actually gets to a point of insertion, the listener throws an error in which it can't find the current transaction given by JPA:
org.hibernate.envers.exception.AuditException: Unable to create revision because of non-active transaction
at org.hibernate.envers.event.spi.BaseEnversEventListener.checkIfTransactionInProgress(BaseEnversEventListener.java:132)

Looking inside the code, it seems that it's basing the transaction status off it's default value of INACTIVE meaning that it's not hooking into the transaction properly. I know that Hibernate Envers also automatically pushes the listeners into hibernate with recent versions so I don't know if this may also be a source of the issue.
I know that its been documented to work with HibernateTransactionManager but we wish to step away from using that in favor of hooking up our transactions and sessions solely via Spring making things easier so it may also be the need of finding an alternative to envers. Does anyone have any advice or solutions to this problem? Or also hit this issue?

<bean
class="path.to.objectDAOImpl">
<property name="sessionFactory">
<ref local="sessionFactory" />
</property>
</bean>
</property>
</bean>
All my services that use the various DAOs are simply hooked up using the #Transactional annotation where we want to have transactions. I've been able to see through trace that my transactions are succeeding in completing and rolling back as well when there are errors. Once I added envers into the mix, the auditing can't find the transaction to join. There must be something I'm missing but I'm not sure what it is.
I don't believe you need to define a txProxyTemplate bean nor a SpringTransactionPolicy from my experience. This functionality has since been superseded with the <tx:/> tags and the use of the #Transactional annotation.
You just need to make sure a JpaTransactionManager has been created and associated as the transactionManager associated with the <tx:annotation-driven/> tag.
I am using spring 3.0.6 Jaxb2Marshaller using below configuration,
<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPaths">
<list>
<value>com.xxx.yyy.schema.external_request.event</value>
<value>com.xxx.yyy.schema.zzz.external_request</value>
</list>
</property>
</bean>
I want to validate xml against against the external_request.xsd which it is not doing. Do I need to explicitly pass the schema property even if the generated sources have the annotation which mentions that element is required something like #XmlElement(name = "abc", required = true). Has any one already faced this issue. Thanks!
Hey may be instead of adding classes to context paths you can try adding it to classesToBeBound proprty
<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>com.xxx.yyy.schema.external_request.event</value>
<value>com.xxx.yyy.schema.zzz.external_request</value>
</list>
</property>

Please rate the answer if it helps.

I have a project with spring and hibernate in GWT,
I am using below applicationcontext.xml,
I was just looking for some best approach of making this file
like all the annotated classes below i.e entity.user, entity.secretQuestion and many more , they all get called when my application runs even if i don't need them , which i guess makes my application quite slow,
so is it possible that only the class which i am calling is getting load in applicationcontext.xml and if yes then would it be a better approach as well ?

You might be looking for something called "lazy loading"
Please take a look at these threads;
Help needed with Spring/Hibernate Lazy-loading
What is lazy loading in Hibernate?
how does spring allow for lazy-loading?
I have a requirement to log business activities that can also map to the audit trail data generated. I use Hibernate envers as the audit trail mechanism.
The way I have implemented the activities log is
I have service classes that are proxied using concrete classes
(using CGLIB) and extend TransactionProxyFactoryBean . This is what
provides the transaction aspect.
My method either has the base object carrying the activity data as
a return type or argument of the service.
The assumption is that when I apply a pre-interceptor on the
TransactionProxyFactoryBean ; its AfterReturningAdvice method
should be called after the transaction is completed.
As per my understanding the pre and post interceptors for the TransactionProxyFactoryBean should behave as follows based on the assumptions that the interceptors are added on the stack.
The pre-interceptors before advice method run
Spring starts the transaction
The post-interceptors before advice method runs
The main service method runs
The post-interceptors after returning advice method runs
Spring commits the transaction
The pre-interceptors after returning advice method runs
However when I de-bugged the application I found that the pre-interceptor's after returning advice method runs before the transaction is commited.
Can anyone please guide me as to what am I doing wrong?

We use the Spring OpenSessionInViewFilter to share the same Hibernate session across the HTTP thread request that comes to the application/web server from GWT.
We also require to have Hibernate sessions available for the cron jobs that are launched using Quartz scheduler. These threads can't use the Hibernate session made available through the OpenSessionInViewFilter and the TransactionProxyFactoryBean proxy that we use to proxy the transactions fails. Hence we needed to use an additional org.springframework.aop.framework.autoproxy.BeanNa meAutoProxyCreator to proxy the polling and SV rule service so that they can be called from the Quartz scheduler.
Because we now had 2 transactional proxies for the same bean; Spring functionality like having pre-interceptor etc was not working as expected because the interceptor was applied on the proxy created with BeanNameAutoProxyCreator and NOT TransactionProxyFactoryBean.
The solution was to move to Spring 2.x transactions using AOP and TX namespace that resulted in creating a single proxy that was utilized by both the OpenSessionInViewFilter and the Quartz scheduler.
Your understanding matches mine.
Would switching to an Around advice (MethodInterceptor) for ActivityLogInterceptor help? If that resolves the issue you may have a bug to report.
greetings all
i am using velocity templates when sending emails
and i want to read texts dynamically from property files depending on user locale
the xml config:
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>classpath:messages</value>
<value>classpath:messages_ar</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8"/>
</bean>
<bean id="velocityEngine"
class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">class</prop>
<prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop>
<prop key="velocimacro.library">org/springframework/web/servlet/view/velocity/spring.vm</prop>
</props>
</property>
</bean>
<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/classes/com/spacerdv/mailTemplates"/>
</bean>
<!--
View resolvers can also be configured with ResourceBundles or XML files. If you need
different view resolving based on Locale, you have to use the resource bundle resolver.
-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".vm"/>
<!-- if you want to use the Spring Velocity macros, set this property to true -->
<property name="exposeSpringMacroHelpers" value="true"/>
</bean>
and when trying to read the text from property file like :
<span>#springMessage("hi.message")</span>
it doesn't read any thing, or prints the default value, just prints:
$springMacroRequestContext.getMessage($code)
i don't know why? , am i missing something ?, any help ?
When using the velocity engine for sending emails, you may have to configure your engine tu use the velocimacro librabry shipped within spring.
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">class</prop>
<prop key="class.resource.loader.class">org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader</prop>
<prop key="velocimacro.library">org/springframework/web/servlet/view/velocity/spring.vm</prop>
</props>
</property>
</bean>
You can check the example in spring documentation.
If Spring doesn't inject automatically the $springMacroRequestContext variable into your model, you should put it yourself:
model.put("springMacroRequestContext", new RequestContext(request, response, getServletContext(), model));
That's basically what they do in the AbstractTemplateView class. I guess you won't be able to do it, since you're handling emails here, and not web requests. But that's definitely a hint on what you can do to get it working.
macros can't be used outside web app like in email templates, so a solution would be to pass messageSource to the vm file and read from the property file by it like the answer in here:
Is it possible to read static text dynamically from property files in velocity template?
