RE: Barracuda: DefaultApplicationAssembler unable to find the assembly-descriptor file

Hi Franck,

Well, I'm not exactly sure why, but my entry looks like this:

<param-name>AssemblyDescriptor</param-name>
<param-value>/WEB-INF/event-gateway.xml</param-value>
             ^
             +---Notice the leading /

Are you using the latest version from cvs? My guess is that Jakes change
here: jrk_120302_1 probably needs to be applied to
ObjectRepositoryAssembler, so as to make them work the same. Jake, you want
to comment on this?
