login.xhtml：请求的资源不可用

Question

I created a Dyamic Web Project in Eclipse to try the login part of the example at http://www.simtay.com/simple-crud-web-application-with-jsf-2-1-primefaces-3-5-maven-and-jpa/ Project Facets I enabled in project properties are:

• CDI
• Dynamic web module
• Java
• JavaScript
• JavaServerFaces
• JPA

and as container I use TomEE.

The moment I try to start the login.xhtml page, I obtain

HTTP Status 404 - /LAI_pezzi_Login/faces/Login.xhtml

type Status report

message /LAI_pezzi_Login/faces/Login.xhtml

description The requested resource is not available.

Apache Tomcat (TomEE)/7.0.37

TomEE console:

SEVERE: StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

PS Can be a problem having libraries in both TomEE and project files? I am forced to do that because when I used Tomcat I missed many libraries and I did not know where to get them, then I moved to TomEE

Answer 1

The webapp's runtime classpath is a mess. The webapp's /WEB-INF/lib seems to contain JSF and JPA libraries which are already provided by TomEE itself as being a Java EE web profile compliant container.

Tomcat is a barebones JSP/Servlet container and does therefore not ship with eg JSF, JPA, EJB, etc. That's exactly why you need to provide and configure JSF, JPA, EJB, etc manually along with the webapp for Tomcat. But for TomEE (and Glassfish, JBoss AS, etc) that's thus absolutely not necessary and would only end up in classloading conflicts because of duplicate different versioned libaries in the runtime classpath.

Get rid of libraries in /WEB-INF/lib which are already provided by the target container itself.
