Portal
Configuration
Here we describe the standard configuration. Depending on the portal server, you might have more than one configuration to set. For more information, please refer to ZK Installation Guide.
WEB-INF/portlet.xml
To use it, you first have to add the following portlet definition for DHtmlLayoutPortlet into WEB-INF/portlet.xml
. Notice that expiration-cache
must be set to zero to prevent portals from caching the result.
<portlet>
<description>ZK loader for ZUML pages</description>
<portlet-name>zkPortletLoader</portlet-name>
<display-name>ZK Portlet Loader</display-name>
<portlet-class>org.zkoss.zk.ui.http.DHtmlLayoutPortlet</portlet-class>

WEB-INF/web.xml
ZK portlet loader actually delegates the loading of ZUML documents to ZK Loader (DHtmlLayoutServlet). Thus, you have to configure WEB-INF/web.xml
as specified in ZK Installation Guide, even if you want to use only portlets.
Use ZK Portlet
The zk_page and zk_richlet Parameter and Attribute
ZK portlet loader is a generic loader. To load a particular ZUML page, you have to specify either a request parameter, a portlet attribute or a portlet preference called zk_page
, if you want to load a ZUML page, or zk_richlet
, if you want to load a richlet.
More precisely, ZK portlet loader first checks the following locations for the path of the ZUML page or the richlet. The lower the number, the higher the priority.
- The request parameter (
RenderRequest
'sgetParameter
) calledzk_page
. If found, it is the path of the ZUML page. - The request attribute (
RenderRequest
'sgetAttribute
) calledzk_page
. If found, it is the path of the ZUML page. - The request preference (
RenderRequest
'sgetPortletPreferences
'sgetValue
) calledzk_page
. If found, it is the path of the ZUML page. - The request parameter (
RenderRequest
'sgetParameter
) calledzk_richlet
. If found, it is the path of the richlet. - The request attribute (
RenderRequest
'sgetAttribute
) calledzk_richlet
. If found, it is the path of the richlet. - The request preference (
RenderRequest
'sgetPortletPreferences
'sgetValue
) calledzk_richlet
. If found, it is the path of the richlet. - The initial parameter (
PortletConfig
'sgetInitParameter
) calledzk_page
. If found, it is the path of the ZUML page.
Examples
How to pass a request parameter or attribute to a portlet depends on the portal. You have to consult the user's guide of your favorite portal for details, or refer to ZK Installation Guide.
