  <p>Presumably the error is occurring because the MyFaces jar files are not in the class path however I cannot figure out where I’m going wrong as the build path in Eclipse contains the required jars. I’ve also tried copying the jar files into the WEB-INF/lib directory but to no avail.</p>
  
  <p>The screenshot below shows the project structure along with the libraries.</p>

  <p>Is there something specific I need to do either in Eclipse or WASCE to include the jar files or does the problem lie elsewhere?</p>
