"JSF - HTTP Status 404 - Not Found" what can it be, even doing the suggested steps?

I’ve been programming for 32 years, but beginner in Java, so whoever votes negative, gentileza comenta o motivo... What may be obvious to you may be unattainable to others.

I started a web project with Maven + JPA/Hibernate + JSF + primefaces.

  • When opening (Tomcat) the index.xhtml file (localhost:8080/new-Hibernate-primefaces/index.xhtml), appear the created Labels, all in a single line, out of formatting..

  • Not even a hello world works (hello.xhtml, when I call hello.jsf)

  • Opening (Tomcat) the index.JSF file (localhost:8080/new-Hibernate-primefaces/index.jsf), causes the error below: Erro 404

ATTEMPTS:

  • I have tried several suggestions from here (en) and from stackoverflow.com, but none of the proposals worked. I’ve also checked the options in properties: "Right click on project", properties, Project Facets --> runtimes: mark: Apache Tomcat V9.0 and DESELECT JRE.

  • I have already deleted and re-configured Tomcat

  • Mark Dynamic Web Module 3.0

  • Select Java, Javascript, Javaserver Faces 2.2, JPA

  • I have also made a new project from scratch and the error persists.

  • An important detail is that, at the time, when I installed Eclipse, I had not marked the "Web Development" option. But now, I’ve added the Webtools packages (I think that’s it).

VERSIONS: Apache Tomcat: 9.0 Eclipse Version: 2020-09 (4.17.0) JDK 11.0.8 (NOT marked in the project, as recommended by the teacher)

Dude, I had a similar problem with you using this version of JSF. When I returned to version 2.2.9 or 2.1.14 of JSF, the problem was quickly resolved. But looking at your code, I realized that the dependencies of Jsf api and impl are with different versions. Try to adjust for identical versions.

<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.2.20</version>
</dependency>
 
<!-- JSF -->
<dependency>

  • Thanks for the attention, @Tguitarful I think, from trying hard, I touched it and did not care to correct, but I did it and continues. http://localhost:8888/new-Hibernate-primefaces/index.jsf -> Error 404 http://localhost:8888/new-Hibernate-primefaces/index.xhtml -> Badly formatted fields

    Dude, I didn’t see any success in version 2.3 of JSF, so much trying, I gave up. I created a pattern in using version 4.0 of the web and 2.2 of JSF and it went smoothly. I’ll take advantage while Tomcat still has support for both.
