hi rene,
this may help or not ... ;-)
i am not 100% sure, but i think, that ivy's URLResolver parses
DirectoryListings. preconditions for URLResolvers to work
would be:
- DirectoryListings must be enabled on server
- DirectoryListings must have the appropriate format
enable DirectoryListings for tomcat like this:
<servlet>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
