Error when publishing Spring application to Geronimo web server

Question

I'm trying to set up Spring with Geronimo web server, but I'm getting the following error:

2010-10-08 18:52:45,105 WARN  [PathMatchingResourcePatternResolver] Cannot search for matching files underneath URL [bundle://316.0:1/com/unveiled/politics/] because it does not correspond to a directory in the file system
java.io.FileNotFoundException: URL [bundle://316.0:1/com/unveiled/politics/] cannot be resolved to absolute file path because it does not reside in the file system: bundle://316.0:1/com/unveiled/politics/

This application seems to work on JBoss AS.

Some other configuration files that matter:

Answer 1

Component-scanning will only work if the application (whether it's an EAR or a WAR) is unpacked by the application on to the filesystem. Appservers generally will do this anyway, for runtime performance reasons.

So it looks like your Geronimo server isn't doing this. Hopefully there's a setting somewhere where you can configure to unpack the app before running it.
