The richlet-mapping Element

Once a richlet is declared, you could map it to any number of URL by using richlet-mapping as depicted below.

<richlet-mapping>
	<richlet-name>Test</richlet-name>
	<url-pattern>/test</url-pattern>
</richlet-mapping>
<richlet-mapping>
	<richlet-name>Test</richlet-name>
	<url-pattern>/some/more/*</url-pattern>
</richlet-mapping>

When mapping, you should consider the servlet-mapping of ZK Loader in web.xml, for example, if you want the Richlet work with /path/*, you may specify the servlet-mapping in web.xml as follows:

<servlet-mapping>
	<servlet-name>zkLoader</servlet-name>
	<url-pattern>/path/*</url-pattern>
</servlet-mapping>

and specify the richlet-mapping as follows:

<richlet-mapping>
	<richlet-name>Test</richlet-name>
	<url-pattern>/*</url-pattern>
</richlet-mapping>

In this case, both Richlet and ZUL will work great. If you swap the url-pattern of servlet-mapping with richlet-mapping, only the Richlet will work well.

Note: Since ZK 7.0.0 release, when use ZK Richlet Filter, the url-pattern of the richlet-mapping should start with the prefix url-pattern in filter-mapping. For example,

In web.xml

<filter>
	<filter-name>RichletFilter</filter-name>
	<filter-class>org.zkoss.zk.ui.http.RichletFilter</filter-class>
</filter>

<filter-mapping>
	<filter-name>RichletFilter</filter-name>
	<url-pattern>/zk/*</url-pattern>
</filter-mapping>

In zk.xml

<richlet-mapping>
	<richlet-name>Test</richlet-name>
	<url-pattern>/zk/foo/*</url-pattern>
</richlet-mapping>

The URL specified in the url-pattern element must start with /. If the URI ends with /*, then it is matched to all request with the same prefix. To retrieve the real request, you can check the value returned by Page.getRequestPath() of the current page.

 public void service(Page page) {
     if ("/some/more/hi".equals(page.getRequestPath()) {
         ...
     }
 }
