java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

Question

I included these in the Build Path:

• all Spring libs
• Apache Tomcat 7.0 library

The project still fails during startup:

Answer 1

I used IntelliJ IDEA, compilation is successful, but when starting Tomcat, it says:

Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

In the beginning, I thought the JAR was missing, but it was in place.

Solution: File > Project Structure > Artifacts, in the Output Layout double click in right panel Available Elements the library named like Maven:..., it will be moved to WEB-INF/lib in the left pane.

Accept and restart Tomcat.
