I need help with Exercise 1 of Lab 4945

[Fernando Aguada]

Hi all,

I followed exercise 1 of lab 4945 step to step, I applied the indications said by Sang, but it didn't work yet.
The error message is next:

SEVERE: Error configurando escuchador de aplicación de clase org.springframework.web.context.ContextLoaderListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
    at java.lang.Thread.run(Thread.java:724)

Also, I attached a picture with libraries. You can see that the libraries are in the project.
Which could be the problem?, any idea?

Thanks in advance.
Fernando

The above error typically occurs when "maven install" is not done (in other words, no compilation
was done).

Please try the following

-remove the app from the server
-perform "maven clean"
-perform "maven install"
-run the app
