zk.xml

WEB-INF/zk.xml is the configuration descriptor of ZK. This file optional. If you need to configure ZK differently from the default, you could provide a file called zk.xml under the WEB-INF directory.

The root element must be <zk>. Then, you could specify any combination of the following element under the root element.

File Location

You can place zk.xml in either a WAR file or a JAR file.

WEB-INF/zk.xml

zk.xml is usually packed with a Web application and it shall be located under WEB-INF.

metainfo/zk/zk.xml

[since 3.6.0]

For library providers, zk.xml is better to be packed with a JAR file. It can be done by placing zk.xml in the metainfo/zk directory identifiable by classpath (i.e., in a JAR file).

Notice that zk.xml found in the classpath is parsed first. It means WEB-INF/zk.xml has higher priority (since it overrides metainfo/zk/zk.xml if conflicts).
