Here is a list of supported preferences that ZK recognizes.

To define a preference, you can configure it in WEB-INF/zk.xml1. The preferences are similar to the library properties: they are application-specific name/value pairs. You could use them to configure your application and ZK engine. However, unlike the library properties, preferences are stored in org.zkoss.zk.ui.util.Configuration and can be retrieved by use of org.zkoss.zk.ui.util.Configuration#getPreference(java.lang.String, java.lang.String).

For example,

<preference>
    <name>org.zkoss.zk.ui.WebApp.name</name>
    <value>My Killer Application</value>
</preference>
