Spring 3.1 - Unable to locate Spring NamespaceHandler - spring

Question

I'm having some Spring 3.1 Namespace problem when I try to run an app on Tomcat 6:
GRAVE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/tx]

All JARs are under WEB-INF/lib and the XML configs are under WEB-INF. Any thoughts?
Thanks in advance, André

Answer 1

Looks like a lib issue . open up the war , search if any spring-tx jar exists . If it exists, and there are no duplicates , open the jar and move to org.springframework.transaction.config and see if the spring-tx-3.1.xsd exists . This is where Spring loads the schema from. If you don't find the jar , it hasn't gotten into your classpath - check the .classpath file . Also keep in mind the duplicates from previous versions .
