java.lang.ClassNotFoundException: org.springframework.web.context.support.StandardServletEnvironment

While upgrading from Spring 3.0.5 to 3.1.1.RELEASE I started getting following exception.

java.lang.ClassNotFoundException: org.springframework.web.context.support.StandardServletEnvironment
	at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714)
	at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559)

After some research I came to conclusion that the file have been factored out into ‘spring-web’ subproject.

So to solve this all we need to do is include ‘spring-web’ dependency

            

         	org.springframework
			spring-web
			${spring.version}
			
				
					commons-logging
					commons-logging
				
			
		

Hope this might help someone save some time.
