Two possible answers   1- You did not include spring-beans and spring-context jars in your lib  If you are using maven   which will help a lot  those two lines will be enough   lt dependency gt    lt groupId gt org springframework lt  groupId gt     lt artifactId gt spring-context lt  artifactId gt      lt version gt 3 1 0 RELEASE lt  version gt   lt  dependency gt   lt dependency gt    lt groupId gt org springframework lt  groupId gt     lt artifactId gt spring-webmvc lt  artifactId gt      lt version gt 3 1 0 RELEASE lt  version gt   lt  dependency gt    2- The necessary jars are in your classpath but are not deployed on tomcat

In my case I get this trouble after using the maven s update project utility  I tried all the workarounds you suggested but nothing seemed to work   At the end the solution was simply to remove the project from the server to ensure that it was clean  and add it again  Then it works  I hope this solution could help any of you

I had this same issue in WebSphere  but couldn t find a solution even though I verified the Spring dependencies were there and it ran in tomcat just fine  I ended up uninstalling the application and was still getting the error so I think WebSphere was hanging onto some corrupt instance   To fix the issue I had to reinstall the application  stop it  uninstall it and then reinstall it

For me it was a mistake in the pom xml - I d set  lt scope gt provided lt scope gt  on my dependencies  and this was making them not get copied during the mvn package stage   My symptoms were the error message the OP posted  and that the jars were not included in the WEB-INF lib path inside the  war after package was run   When I removed the scope  the jars appeared in the output  and all loads up fine now

You can use GlassFish server and the error will be resolved  I tried with tomcat7 and tomcat8 but this error was coming continuously but resolved with GlassFish  I think it s a problem with server   These are the results with tomcat7    Here are the results with GlassFish
