JSF: /WEB-INF/*/javax.faces.resource/theme.xhtml Not Found in ExternalContext as a Resource (Primeface's resource URI has asterisk sign)

Question

Using JSF, Spring, Spring WebFlow, PrimeFaces. I'm trying to open simple 'hello world' page. Page itself is opened, but it throws such exception that it is not able to include Primeface's theme:

Page is being generated with such CSS link which contains also asterisk sign in href:

<link type="text/css" rel="stylesheet" href="/spring/*/javax.faces.resource/theme.css?ln=primefaces-aristo">

CSS itself without asterisk can be opened correctly with following link:

.../spring/javax.faces.resource/theme.css?ln=primefaces-aristo

Answer 1

Solved issue updating url-pattern to:

<servlet-mapping>
        <servlet-name>springFlowApplication</servlet-name>
        <url-pattern>/app/*</url-pattern>
</servlet-mapping>

It would be very good if somebody could explain why needed to add '/app', because now whole URL also contains '../app/..', which is not very nice looking ...
