Hi,
i'm writing a portlet that use ajax4jsf library, but i have some problems during deployment phase. First i've tried to add the following to web.xml of my portlet :

 <filter>
 <display-name>Ajax4jsf Filter</display-name>
 <filter-name>ajax4jsf</filter-name>
 <filter-class>org.ajax4jsf.Filter</filter-class>
 </filter>

 <filter-mapping>
 <filter-name>ajax4jsf</filter-name>
 <servlet-name>Faces Servlet</servlet-name>
 <dispatcher>REQUEST</dispatcher>
 <dispatcher>FORWARD</dispatcher>
 <dispatcher>INCLUDE</dispatcher>
 </filter-mapping>

but i've go an exception :

ava.lang.IllegalStateException: No Factories configured for this Application - typically this is because a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
 <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

 at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:3600)

Then i've tried to specify full configuration of myfaces in my web.xml but i've got the same exception.
I've tried to use the portlet as a standalone web application and when i have deployed in jboss it works!
Next i make the same but in the web.xml of portal-core.war but return to have the same exception.
There is a way to have this working on a portlet ?
Thanks to all
