How to write *-portal.xml - files ?

[sessa]

Hi !

I still try to create my own layout and a own portlet instance.

I defined a my own helloworld-portal.xml file.

If i delete all between , the portlet instance is running.
But if i copy paste the default properties, i get this exeption:
------------------------------------------------------------

13:09:54,970 WARN [InvocationImpl] Cannot find default window CMSPortletWindow in portal helloworld
13:09:55,000 INFO [STDOUT] Initializing web-app from stream with InputStream.
13:09:55,611 INFO [STDOUT] WURFL has been initialized
13:09:55,681 ERROR [CoreServlet] Exception caught in processing servlet
java.lang.NullPointerException
 at org.jboss.portal.core.theme.strategy.StrategyFactory.createStrategyContext(StrategyFactory.java:55)

------------------------------------------------------------

Seems that JBOSS doesn't like that i deleted "CMSPortletWindow" in the page declaration in the same file.

But there have to be a way not to use CMSPortletWindow, right ?

my properties read as the following:
------------------------------------------------------------

 <properties>
 <!-- Set the default window for request of the type /a/b/c -->
 <property>
 <name>org.jboss.portal.property.action</name>
 <value>CMSPortletWindow</value>
 </property>
 <!-- Set the layout for the default portal -->
 <!-- see also portal-layouts.xml -->
 <property>
 <name>org.jboss.portal.property.layout</name>
 <!-- <value>nodesk</value> -->
 <value>FoLayout</value>
 <!-- <value>CarStoreLayout</value> -->
 </property>
 <!-- set the default render set name (used by the render tag in layouts) -->
 <!-- see also portal-renderSet.xml -->
 <property>
 <name>org.jboss.portal.property.renderSet</name>
 <!-- <value>emptyRenderer</value> -->
 <value>divRenderer</value>
 </property>
 <!-- set the default strategy name (used by the strategy interceptor) -->
 <!-- see also portal-strategies.xml -->
 <property>
 <name>org.jboss.portal.property.strategy</name>
 <value>default</value>
 </property>
 </properties>

------------------------------------------------------------

Where can i find some information about writing *-portal.xml files ?

JBOSS portal 2.0 final reference guide and user guide don't say a word about the properties tags in the *-portal.xml file.

thanks.
