Guys I’m starting to study Jboss, Maven, etc. However when I run a page I created for tests this error appears:

Could not find backup for factory javax.faces.context.FacesContextFactory

In my project I have a directory called Maven Dependencies and inside it is the . jar javax.faces-api-2. 2.jar Does anyone know what it can be? Thank you

    First of all, if you are in Jboss, you cannot bundle with your JSF application because it is already available within the Jboss itself. In Maven, set JSF to <Scope>provided</Scope>, restart your application, and tell if the error remains the same. It would also be good if you edit the question and put your faces-config.xml, pom.xml and web.xml.

  • That’s right, I put the <Scope>provided</Scope> and it worked. Post this comment as an answer so that I mark as a solution

If you are in Jboss, you cannot pack any jar related to JSF with your application because it is already available inside the Jboss itself (See this link available resources within a JEE 6 container). On Maven, set JSF to provided:

<dependency>
    <groupId>com.sun.faces</groupId>
    <artifactId>jsf-api</artifactId>
    <version>2.2.0</version>
    <scope>provided</scope>
</dependency>
