10.1.10 config-param

JSR 168 portlets use a PortletPreference object instead of the PortletData and PortletSettings objects. If you have defined any config-param elements in your portlet.xml, you should convert these to portlet-preference elements.

Change:

Example 10-5 config-param in portlet.xml 

<config-param>
 <param-name>favoriteFood</param-name>
 <param-value>Pizza</param-value>
</config-param>

to:

Example 10-6 portlet-preference 

<portlet-preferences>
 <preference>
  <name>favoriteFood</name>
  <value>Pizza</value>
  <read-only>true</read-only>
 </preference>
</portlet-preferences>

The preference element contains a read-only element. If the preference is read-only, only the administrator can update this preference.
