[opencms-dev] OpenCms and ZK

[Roman Uhlig]

Option C sounds great to me. Unfortunately I don't have any idea about
writing filters in web.xml :(

The default ZK web.xml contains the following part (disabled by default).
Any ideas how this could help:

<filter>
	<filter-name>zkFilter</filter-name>
	<filter-class>org.zkoss.zk.ui.http.DHtmlLayoutFilter</filter-class>
	<init-param>
		<param-name>extension</param-name>
		<param-value>html</param-value>
	</init-param>
</filter>
<filter-mapping>
	<filter-name>zkFilter</filter-name>
	<url-pattern>/test/special.jsp</url-pattern>
</filter-mapping>


Thanks,
Roman
