More than one fragment with the name [spring_web] was found. This is not legal with relative ordering

add <absolute-ordering /> tag to your web.xml just under the <display-name> tag. should work.

Sounds like you have two different versions of Spring, check your dependencies to see if you have a dependency to another Spring-version.

mvn dependency:tree -Dverbose -Dincludes=groupId:artifactId

Cleaning the server worked for me. Just do the following :

Right click on the server -> Clean.

Then redeploy the app on the server.
