Hi Enrico The stack suggests that Jena RIOT calls the apache HTTP client. The HTTP client Apache uses commons logging for logging. In this case not the original one, but the adapter for SLF4J - log4j-over-slf4j) - see LogFactory.getLog(..) calling SLF4JLogFactory.
So IMO this is caused by the version of the "slf4j-api" being incompatible with the version of the "log4j-over-slf4j". So to solve this you will need to find out how the outdated "log4j-over-slf4j" comes into your classpath and replace it with one that is compatible to the "slf4j-api" used by the OSGI environment. best Rupert On Tue, Nov 19, 2013 at 11:56 AM, enridaga <enrid...@apache.org> wrote: > Unfortunately option 2) is less easy as expected.
