Spring 3.1 contextInitializerClasses not Working on WebLogic 10.3.6 using web.xml Context-Param
The name of the context-param is I think wrong, it should be contextInitializerClasses not contextInitializerClass , that could be the reason why your ApplicationContextInitializer is not getting picked up
Also you seem to be missing the entry for ContextLoaderListener in your web.xml file, try adding that too:
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>This is the one which loads up the bean configuration xml file specified in the contextConfigLocation tag
