Extensionless URLs with JSF 2.3 - jsf

Question

JSF 2.3 Extensionless URLs as explained here not working for my enterprise app. When navigating to url without .xhtml extension, FileNotFoundException exception is thrown:
Warning: JSF1091: No mime type could be found for file /pages/najmovi. To resolve this, add a mime-type mapping to the applications web.xml.

Servlet-mappings in web.xml are configured: prefix /app/* and suffix *.xhtml
Also, there is an authentication filter #WebFilter for pattern /app/pages/* (similar to this)
Server: GlassFish ver-5.0; some other JSF 2.3 features are working fine.

Answer 1

I hade the same issue using JBoss EAP 7.0. Although it is claimed you can use extensionless URL's it is not working out of the box with only JSF 2.3 code (like in the blog you mention). I have yet to see a working example which works on all application servers without additional framework.
I use Rewrite because the configuration is simple and works out of the box. An alternative could be Omnifaces, but because we use JBoss EAP 7.0 and Omnifaces needs a (dirty!) workaround to get it running on JBoss EAP 7.0 (Why is WildFly 10 + JSF 2.3 not working with Omnifaces 2.6.1?) we abandoned Omnifaces. The link mentioned Wildfly 10, but it is applicable also to EAP 7.0.x versions.
This is my maven dependency:
<dependency>
<groupId>org.ocpsoft.rewrite</groupId>
<artifactId>rewrite-servlet</artifactId>
<version>3.4.2.Final</version>
</dependency>
This is my Rewrite configuration:
import javax.servlet.ServletContext;
import org.ocpsoft.rewrite.annotation.RewriteConfiguration;
import org.ocpsoft.rewrite.config.Configuration;
import org.ocpsoft.rewrite.config.ConfigurationBuilder;
import org.ocpsoft.rewrite.servlet.config.HttpConfigurationProvider;
import org.ocpsoft.rewrite.servlet.config.rule.Join;
/**
* Configuration file to ensure extensionless url's with Rewrite framework from ocpsoft
*
*
* #since 1.0.0
*
*/
#RewriteConfiguration
public class ExtensionlessConfiguration extends HttpConfigurationProvider {
/*
* (non-Javadoc)
*
* #see org.ocpsoft.common.pattern.Weighted#priority()
*/
#Override
public int priority() {
return 10;
}
/*
* (non-Javadoc)
*
* #see org.ocpsoft.rewrite.config.ConfigurationProvider#getConfiguration(java.lang.Object)
*/
#Override
public Configuration getConfiguration(final ServletContext context) {
return ConfigurationBuilder.begin().addRule(Join.path("/beheer").to("/beheren/welkom.xhtml")).addRule(Join.path("/{param}").to("/{param}.xhtml"))
.addRule(Join.path("/").to("/welkom.xhtml")).addRule(Join.path("/beheren/{param}").to("/beheren/{param}.xhtml"));
}
}
This will map following pages to extensionless URL's:
Basic application URL / will be mapped internally to welkom.xhtml, like in web.xml welcome list, which in turn will be mapped without extension thanks to point 2. So for instance www.inter.it will be mapped internally to www.inter.it/welkom.xhtml.
All pages in root application will be without .xhtml. So for instance www.inter.it/welkom.xhtml will be mapped to www.inter.it/welkom
All pages under /beheren folder will be without .xhtml. So for instance www.inter.it/beheren/team.xhtml will be mapped to www.inter.it/beheren/team
SAML entrypoint URL /beheer will be mapped internally to /beheren/welkom.xhtml, which in turn will be mapped without extension thanks to point 3. So for instance www.inter.it/beheer will be mapped to www.inter.it/beheren/welkom.xhtml
Good luck with it ;-)
