Spring mvc framework context loaded twice??

Context

I have developed the simple scheduler (task timer) application using spring framework with mvc.
Application only log "Hello!!" string every 10 seconds.

Code example

spring-servlet.xml:



web.xml:






Surprisingly in logs I've noticed double logs with hello string?? WTF?

Looking into context start logs

 Solution

Context was loaded twice from /WEB-INF/springmvc-servlet.xml config file.  

contextConfigLocation is uncorrectly invoke. It should point on spring application context definition (different than servlet definition - springmvc-servlet.xml).

Changing to other applicationConfig.xml should help fix the problem:
