No declaration can be found for element 'webflow:flow-builder-services'

Question

I'm trying to integrate SWF in Spring mvc application for the first time, but I'm getting this error :

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException in XML document from ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: XX; columnNumber: XX; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'webflow:flow-builder-services'

this is my mvc-dispatcher-servlet.xml file (referenced by contextConfigLocation in web.xml)

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:webflow="http://www.springframework.org/schema/webflow-config"

I'm using spring 3.0.3.RELEASE and spring webflow 2.1.1.RELEASE

Do you have an explanation about this issue ?

Thanks in advance

According to this post http://stackoverflow.com/questions/6058037/the-matching-wildcard-is-strict-but-no-declaration-can-be-found-for-element-tx it can be version mismatch, for axample you declare http://www.springframework.org/schema/beans/spring-beans-2.5.xsd but use spring 3.0.3.RELEASE. — erhun, Jan 20 '14 at 15:21

Change your spring beans schema version. You're using 2.5, but it should be 3.0.

You are right guys !

It was a version mismatch. I also changed my spring webflow schema version to http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.0.xsd as I'm using SWF 2.1.1.RELEASE

PS: It's also important to verify spring jars downloaded by maven, and compare their versions to the ones declared in schema location. (If spring-webflow 2.1.1 is used, the schema location must declare spring-webflow-config-2.0 not spring-webflow-config-2.3, same thing for the other spring jars/schema declarations)
