jsf – java. lang.ClassNotFoundException：javax. faces. webapp. FacesServlet

I received this error when executing JSF and primefaces

I've included these cans,

> jsf-api-2.0. 3.jar, > jsf-impl-2.0. 3.jar, > jstl-1.0. 2. Jar and > primefaces-2.2 RC2. jar

In the web - inf / lib folder

Do I have any lost cans?

Solution

Obviously, you haven't lost anything Just try the following:

>Ensure that the required jars exist in the "lib" project folder; Clean & build;

Finally, you should find the jar contained in the "build" project folder
