I implemented the Richlet example:
(I am using apache-tomcat-7.0.8 with zk-5.0.7.1)

1 package hpcgateway.workspace.worker;
2
3 import org.zkoss.zk.ui.Page;
4 import org.zkoss.zk.ui.GenericRichlet;
5 import org.zkoss.zk.ui.event.*;
6 import org.zkoss.zul.*;
7
8
9 public class Main extends GenericRichlet {
10 public void service(Page page) {
11 page.setTitle("Hpcgateway Workspace");
12 final Window w = new Window("main window", "normal", false);
13 new Label("start").setParent(w);
14 final Label l = new Label();
15 l.setParent(w);
16
17 final Button b = new Button("change");
18 b.addEventListener(Events.ON_CLICK, new EventListener() {
19 int count;
20 public void onEvent(Event et) {
21 l.setValue("" + count);
22 }
23 });
24 b.setParent(w);
25 w.setPage(page);
26 }
27 }

and zk.xml:
1 <?xml version="1.0" encoding="UTF-8"?>
2 <zk>
3 <richlet>
4 <richlet-name>Test</richlet-name>
5 <richlet-class>hpcgateway.workspace.worker.Main</richlet-class>
6 </richlet>
7 <richlet-mapping>
8 <richlet-name>Test</richlet-name>
9 <url-pattern>/test</url-pattern>
10 </richlet-mapping>
11 </zk>

web.xml:
....
39 <servlet-name>zkLoader</servlet-name>
40 <url-pattern>/do/*</url-pattern>
41 </servlet-mapping>
....

but when access the address http://localhost/services/do/test
it reports an exception:
