Adding JSF in java project

Question

I created a Maven project in Intellij IDEA 2016.2, defined it as a Web Application, and later installed JSF.

Before installing the JSF the framework added the index.jsp file, which works normally, after adding the JSF created a new file called index.xhtml, but when trying to open it the Tomcat returns me:

HTTP Status 404 - type Status report

message

Description The requested Resource is not available.

Answer 1

Well, I don’t understand the version of your JSF dependency. Try replacing it with the following (or you can choose another one from the Maven repository).

<dependency>
    <groupId>javax.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.1</version>
</dependency>

Another thing I noticed is that if it’s a Maven project, your views shouldn’t be in the folder webapp?

Following the directory logic:

• src/main/java: package-organized application source code;
• src/main/Resources: resources the application needs;
• src/main/webapp: directory for web applications, web.xml, images,
  HTML and XHTM’s;
• src/test/java: unit tests;

Also check if in the configuration file web.xml is this way:

  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>

The *.xhtml says that the index to be searched will be the index.xhtml and not the .jsp

PS - The JSF -Java Server Faces not installed, it is only a specification. It is in charge of the implementations, for example Mojarra and Myfaces, make available their libraries that meet this JCP standard.
