Barracuda: DefaultApplicationAssembler unable to find the assembly-descriptor file

Hi,

I'm trying to learn how to use the application assembly descriptor in 
Barracuda (until now, I used plain servlet extending from 
ApplicationGateway).

I have a very simple file called event-gateway.xml in the WEB-INF/ 
directory of my web app.

When I deploy the app (under jboss 3.0.4 / Tomcat 4.1.12 bundle), I get 
an exception saying DefaultApplicationAssembler is unable to find the 
assembly descriptor file.

Notice the object respository assembler works just fine, with an 
object-repository.xml file beeing in the same place.

May this be connected with my failing unit test (see thread about 
comiling under jdk 1.3.1) ??
I've seen a comment in DefaultApplicationAssemble saying it was dealing 
with file separator...

Any idea ?

Thanks,

Franck


Here is a snippset of my web.xml file :

<servlet>
<servlet-name>ApplicationGateway</servlet-name>
<servlet-class>org.enhydra.barracuda.core.event.ApplicationGateway</servlet-class>
<init-param>
<param-name>ApplicationAssembler</param-name>
<param-value>org.enhydra.barracuda.core.event.DefaultApplicationAssembler</param-value>
</init-param>
<init-param>
<param-name>AssemblyDescriptor</param-name>
<param-value>WEB-INF/event-gateway.xml</param-value>
</init-param>
<init-param>
<param-name>SAXParser</param-name> 
<param-value>org.apache.xerces.parsers.SAXParser</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>


And I get the following log :
