To enable a new skin, you must add the ‘yfc-ui-skin' context parameter in the INSTALL_DIR/repository/eardata/platform/descriptors/weblogic/WAR/WEB-INF/web.xml file. The name of the new skin should be specified as value of this parameter. For example, the entry in the web.xml file will look like this:
<context-param>
<param-name>yfc-ui-skin</param-name>
<param-value>skin_name</param-value>
</context-param>
