Question

i downloaded the 3.3.1-SNAPSHOT version to make generic url
regarding this post:

Pretty Faces: Generic URL mapping

my configuration is as follows:

the following line keeps repeating in terminal:

Mika,

This is not something that PrettyFaces supports using the URL-mapping construct, you must instead use a custom rewrite rule:

<rewrite match="/(.*)" substitute="/faces/$1.xhtml" />

However, consider the impact of such a rule (similar to the one you defined above.) Of course there will be an infinite loop, because “*” also matches “/faces/XXX.xhtml”. You need to make your match pattern more restrictive.

<rewrite match="^/(.*)(?<!\.xhtml)$" substitute="/faces/$1.xhtml" />

I also suggest you read up on Regular expressions, because “/*” is not a regular expression that will do what you seem to think it will do: http://ocpsoft.com/opensource/guide-to-regular-expressions-in-java-part-2/#lookaround

However, if you want a URL-rewriting tool which was designed specifically to perform tasks like this, then I suggest you look at OCPsoft Rewrite: http://ocpsoft.com/rewrite/, a much more powerful (but more difficult to use) URL-rewriting tool.

It allows you to do things like this:

       .addRule(Join.path("/{page}")
                .to("/pages/{page}.xhtml")
                .when(Resource.exists("/pages/{page}.xhtml"))
                .where("page").matches("(?!RES_NOT_FOUND)[^/]+"))
