Hi All,

I'm using STS 3.0.0 and I'm having the following error message when starting my mvc-hibernate-declarative transaction application:

ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanDefinitionSt oreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/spring/root-context.xml]; nested exception is org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.springframework.transaction.config.TxNamespace Handler] for namespace [http://www.springframework.org/schema/tx]: problem with handler class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/context/config/AbstractSpecificationBeanDefinitionParser
at org.springframework.beans.factory.xml.XmlBeanDefin itionReader.doLoadBeanDefinitions(XmlBeanDefinitio nReader.java:412)...........



I don't know why this is occurring.

Thank you very much in advance.
