DHtmlUpdateServlet
[Required] Class: DHtmlUpdateServlet
ZK AU Engine, aka., ZK Update Engine, is a servlet that handles AJAX requests asynchronously and automatically.
Notice that the URL pattern mapped to this engine must be consistent with the update-uri parameter of ZK Loader.
Here is a complete sample.
The Initial Parameters
| compress | [Optional][Default:true][since 3.6.3]
<init-param>
<param-name>compress</param-name>
<param-value>false</param-value>
</init-param>
|
| extension0
extension1 extension2 ... |
[Optional] [since 5.0]
It specifies an AU extension The first processor must be specified with the name called The syntax of the value is /prefix=class For example, <init-param>
<param-name>extension0</param-name>
<param-value>/upload=com.super.MyUploader</param-value>
</init-param>
<init-param>
<param-name>extension1</param-name>
<param-value>/extra=com.super.MyExtra</param-value>

Map URL to ZK AU Engine
Mapping URL to ZK AU Engine is straightforward:
<servlet>
<servlet-name>auEngine</servlet-name>
<servlet-class>org.zkoss.zk.au.http.DHtmlUpdateServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>auEngine</servlet-name>
<url-pattern>/zkau/*</url-pattern>
</servlet-mapping>
Notice that the URL pattern mapped to this engine must be consistent with the update-uri parameter of ZK Loader.
Here is a complete sample.
