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

Same thing happens to me from time to time when using Eclipse WDT. Its specialy frustrating when this happens to a unmodified and previously working project. This is what I do to fix it in this last scenario:

1. Stop Tomcat (if it's running)
2. Open the "Servers" view: Window > Show view > Other > Server > Servers
3. Right Click on Tomcat Server > Clean Tomcat Work Directory.
4. Right Click on Tomcat Server > Clean
5. Restart the server

This usually fixes the issue you mention.
