I referred your tutorial "Spring 3 MVC and Hibernate 3 Example" and downloaded your source codes. I created a build.xml and built it using ant. And copied to Jboss server and tried to run the project, but there is a error threw to jboss console which mentioned
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'articleDao': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory net.roseindia.dao.ArticleDaoImpl.sessionFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.
So please help me to solve this problem. I want to know is something missing on your dispatcherservlet-xml file?
