Hello. Help, please, to solve a problem.

Wrote an application on EJB. I displayed variables on the page using jsf
index.xhtml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html">
<h:head>
    <title>JSF 2.0</title>
</h:head>
<h:body>
    <h3>Enter tariff title</h3>
    <h:form>
        <h:inputText value="#{beanController.tariff}"></h:inputText>
        <br/>
        <br/>
        <h:commandButton value="Get report" action="#{beanController.getInfo}"></h:commandButton>
    </h:form>
</h:body>
</html>

However, I need to re-render this page. An example of design is in jsp. And this is where the problems begin. If you rename xhtml to jsp , jsf stops working, if vice versa, then jsp.
What is the correct way to make jsf tags work in jsp files?

In my opinion JSP and JSF are 2 different versions of the same thing. Those. You need to use one. If we take JSP, then we need to use JSTL . We change the sign '#' to '$' and live happily ever after.

It can be done, but as Eugene noted above, it does not make practical sense. The only case I can think of is the gradual migration of a project from jsp to jsf or vice versa.
Try configuring DEFAULT_SUFFIX and FACELETS_VIEW_MAPPINGS by adding to web.xml

<web-app>
    <context-param>
        <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
        <param-value>.jsp</param-value>
    </context-param>

    <!-- Facelets pages will use the .xhtml extension -->
    <context-param>
        <param-name>facelets.VIEW_MAPPINGS</param-name>
        <param-value>*.xhtml</param-value>
    </context-param>     

    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    </servlet>

    <!-- Use prefix mapping for Facelets pages, e.g. http://localhost:8080/webapp/faces/mypage.xhtml -->
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
</web-app>

Although I can't say how much this will help without seeing the code in the controllers. Still, these are different ways of building applications.
