javax.faces.context.FacesContextFactory Exception while embedding Undertow with JSF application - jsf

Question

I am trying to build a simple JSF web application using embedded Undertow server.
Gradle dependencies for the project:
dependencies {
compile group: 'io.undertow', name: 'undertow-core', version: '1.4.0.CR3'
compile group: 'io.undertow', name: 'undertow-servlet', version: '1.4.0.CR3'
compile group: 'javax', name: 'javaee-api', version: '7.0'
compile group: 'org.glassfish', name: 'javax.faces', version: '2.2.11'
}
Sample Undertow Server Code:
public class HelloWorldServer {
public static void main(final String[] args) throws ServletException {
DeploymentInfo servletContainer=Servlets.deployment()
.setClassLoader(HelloWorldServer.class.getClassLoader())
.setDeploymentName("helloWorld.war")
.setContextPath("")
.addServlet(Servlets.servlet("javax.faces.webapp.FacesServlet",FacesServlet.class)
.addMappings("/faces/*","/javax.faces.resource/*")
.setLoadOnStartup(1));
DeploymentManager manager=Servlets.defaultContainer().addDeployment(servletContainer);
manager.deploy();
HttpHandler servletHandler=manager.start();
PathHandler path = Handlers.path(Handlers.redirect(""))
.addPrefixPath("/", servletHandler);
Undertow server = Undertow.builder()
.addHttpListener(8080, "localhost")
.setHandler(path)
.build();
server.start();
}
}
When i start the server,following error comes:
Mar 07, 2017 6:04:49 PM javax.faces.FactoryFinder$FactoryManager copyInjectionProviderFromFacesContext
SEVERE: Unable to obtain InjectionProvider from init time FacesContext. Does this container implement the Mojarra Injection SPI?

Answer 1

Finally i found a solution.
For JSF bootstrap process we must add Two additional init parameter to Undertow DeploymentInfo class.
com.sun.faces.forceLoadConfiguration = TRUE
com.sun.faces.expressionFactory = com.sun.el.ExpressionFactoryImpl
Also we must add two more extra dependency other than JSF.
el-api
el-impl
