I am using Maven to download ICEfaces dependencies:
<dependency>
<groupId>org.icefaces</groupId>
<artifactId>icefaces</artifactId>
<version>3.3.0</version>
</dependency>
<dependency>
<groupId>org.icefaces</groupId>
<artifactId>icefaces-compat</artifactId>
<version>3.3.0</version>
</dependency>
<dependency>
<groupId>org.icefaces</groupId>
<artifactId>icefaces-facelets</artifactId>
<version>1.8.2</version>
</dependency>
I checked the Binaries and the Sources from the official ICEfaces website, both zip files does not contain the xmlhttp folder which contains the CSS files for the themes.
Adding the following in web.xml file doesn't change anything:
<context-param>
<param-name>org.icefaces.ace.theme</param-name>
<param-value>rime</param-value>
</context-param>
