Tomcat 7 “SEVERE: A child container failed during start”

Question

Basically, I\'ve written a springMVC application (with a relatively shotgun my way first-timer approach with regards to Spring). The project works fine on Tomc

Answer 1

I have seen this exception while tomcat started and it almost took many hours to figure out the reason. Finally I found out that there were some Spring JARs of a lower version in the lib folder in addition to the Spring jars in the Maven dependencies. The JARs in the lib were automatically added by Eclipse when I added a new Spring Rest controller. I removed those from the lib folder and then let Maven handle the JARs/dependancies and it was fine. Bottom line is if the JARS managed by maven and jars in the WEB-INF/lib causes a classpath issues, you may encounter this error.
