What does it mean? class for namespace does not implement the interface

[NewToSpring99]

Hi,

I'm getting this error when I go to the address in a new browser (I'm deploying a project using spring security in Servicemix Fuse ESB osgi container).

Error 500

Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/config/springsecurity.xml]; nested exception is org.springframework.beans.FatalBeanException: Class [org.springframework.security.config.SecurityNamesp aceHandler] for namespace [http://www.springframework.org/schema/security] does not implement the [org.springframework.beans.factory.xml.NamespaceHan dler] interface


Can anyone help me understand what it means, and how I should go about solving it?

Just a thought, but it may be an idea to post your question on one of the OSGI forums because the error sounds osgi related
