I have Login.xhtml
and Home.xhtml
. I configured the url pattern in web.xml
as follows
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>Login.xhtml</welcome-file>
</welcome-file-list>
When I run the whole project, the login page URL
is like this http://localhost:8080/fran/Login.xhtml
, here fran
is my project name..
However, I would like it to be http://localhost:8080/fran/Login/
instead of http://localhost:8080/fran/Login.xhtml
.
How can I achieve this? Is it possible to customize the <url-pattern>
for every page to get rid of the .xhtml
extension?
If your sole reason is to get rid of the .xhtml
extension, then there are various ways depending on the JSF version you're using.
JSF 2.3 offers a new API to collect all views: the ViewHandler#getViews()
. Combine this with ServletRegistration#addMapping()
in a ServletContextListener
as below.
@FacesConfig
@WebListener
public class ApplicationConfig implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent event) {
addExtensionLessMappings(event.getServletContext(), FacesContext.getCurrentInstance());
}
private void addExtensionLessMappings(ServletContext servletContext, FacesContext facesContext) {
servletContext
.getServletRegistrations().values().stream()
.filter(servlet -> servlet.getClassName().equals(FacesServlet.class.getName()))
.findAny()
.ifPresent(facesServlet -> facesContext
.getApplication()
.getViewHandler()
.getViews(facesContext, "/", ViewVisitOption.RETURN_AS_MINIMAL_IMPLICIT_OUTCOME)
.forEach(view -> facesServlet.addMapping(view))
);
}
}
Effectively, this is an oneliner. Source: Arjan Tijms' Blog and The Definitive Guide to JSF.
If you're using MyFaces as JSF 2.3 implementation, then this can be transparently activated by solely the following web.xml
context parameter:
<context-param>
<param-name>org.apache.myfaces.AUTOMATIC_EXTENSIONLESS_MAPPING</param-name>
<param-value>true</param-value>
</context-param>
Mojarra does not have an equivalent yet.
Use OmniFaces FacesViews. It offers a zero-configuration way to achieve that by placing the view files in /WEB-INF/faces-views/
folder. Otherwise, if you intend to not modify your project structure and want to keep your view files at the usual place and still benefit of extensionless URLs, then it's a matter of adding the following context parameter:
<context-param>
<param-name>org.omnifaces.FACES_VIEWS_SCAN_PATHS</param-name>
<param-value>/*.xhtml</param-value>
</context-param>
In case you don't want to use OmniFaces, but rather want to homegrow your own, just look at source code of OmniFaces. It's open source under Apache 2.0 License. It's only not an oneliner.
