How to create user-friendly and seo-friendly urls in jsf?

For example, I have class Article with methods getTitle () and getContent ().

I also have ArticlesService with method getAllArticles (). How to create a list of links with meaningful names (formed with #{article.title})? Like:

http://mysiteaddress.com/article/first-article-title
http://mysiteaddress.com/article/how-to-make-links-in-jsf

..or something similar.

I can create links with all necessary functionality with <h:commandLink>, but I don't know how to make nice 'href' for it: it always has href '#'.

I can create nice links with <h:outputLink> but I don't know how to add necessary functionality to it.


In jsp I created my own front-controller, which parsed urls from requests and then performed redirection to correspondent jsp-page.

How to achieve the same functionality in JSF?

If this is intended as an improvement of an existing application, then you basically need a Filter which detects "dirty" and "friendly" URLs. When it detects a "dirty" URL, then it should redirect the request to a "friendly" URL by HttpServletResponse#sendRedirect(). When it detects a "friendly" URL, then it should forward the request to the "dirty" URL by RequestDispatcher#forward(). An example can be found in this related question: How to use a servlet filter in Java to change an incoming servlet request url?

Further, you also need a custom ViewHandler to produce the desired "friendly" URL for JSF <h:form>, <h:link>, etc. An example can be found here: Dynamic Directory in Java EE Web Application.

If this is a new application or an application which is open to changes, you could consider any of the existing pretty URL libraries instead of reinventing the wheel:

  • PrettyFaces, which is a complete URL rewrite solution. It requires an additional XML configuration file pretty-config.xml. This library is useful if you want to completely change URLs and/or want to configure redirects from old to new URLs.
  • FacesViews of OmniFaces library, which makes existing URLs just extensionless by a single web.xml context param. It also supports "MultiViews" whereby path parameters can declaratively be injected in managed beans. E.g. /foo/bar/baz can point to /foo.xhtml and the values bar and baz can be injected by @Param(pathIndex).

There's also the experimental PrettyUrlPhaseListener of Mojarra Scales library, but it's an old library and PrettyFaces is largely based on it, so it's not worth the effort.

Did you tried PrettyFaces?

Simple, effective, bookmark, JSF

PrettyFaces is an OpenSource extension for JSF1.2 and JSF2.0, which enables creation of bookmark-able, pretty URLs. PrettyFaces solves this problem elegantly, including features such as: page-load actions, seamless integration with faces navigation, dynamic view-id assignment, managed parameter parsing, and configuration-free compatibility with other JSF frameworks.

SEO and Consistency:

Any business knows how important Search Engine Optimization can be for sales. PrettyFaces allows SEO-friendly URLs, and improved customer experience. Give your site a uniform, well understood feeling, from the address bar to the buy button.
