These should be warnings or informational at most, as the package still operates properly without the missing parser factories. <br/> <br/> See below for a stack trace. <br/> <br/> ERROR (org.openrdf.rio.RDFParserRegistry:58) Failed to instantiate service <br/> sun.misc.ServiceConfigurationError: org.openrdf.rio.RDFParserFactory: Provider org.openrdf.rio.trig.TriGParserFactory not found <br/> at sun.misc.Service.fail(Service.java:129) <br/> at sun.misc.Service.access$000(Service.java:111) <br/> at sun.misc.Service$LazyIterator.next(Service.java:273) <br/> at info.aduna.lang.service.ServiceRegistry.&lt;init&gt;(ServiceRegistry.java:42) <br/> at info.aduna.lang.service.FileFormatServiceRegistry.&lt;init&gt;(FileFormatServiceRegistry.java:20) <br/> at org.openrdf.rio.RDFParserRegistry.&lt;init&gt;(RDFParserRegistry.java:33) <br/> at org.openrdf.rio.RDFParserRegistry.getInstance(RDFParserRegistry.java:26) <br/> at org.openrdf.rio.Rio.createParser(Rio.java:167) <br/> at org.openrdf.rio.Rio.createParser(Rio.java:188) <br/> at org.openrdf.repository.base.RepositoryConnectionBase.addInputStreamOrReader(RepositoryConnectionBase.java:373) <br/> at org.openrdf.repository.base.RepositoryConnectionBase.add(RepositoryConnectionBase.java:277) <br/> <br/> I would prefer not to have to filter these messages, as I would like to see Sesame/Rio errors in my logs if they are legitimate. sesame-2.4.0 RIO-76 RdfParserRegistry prints error to logs when it doesn't find a built-in parser factory Bug Minor Closed Won't Fix Arjohn Kampman Peter Ansell Mon, 20 Jun 2011 08:31:58 +0200 (CEST) Fri, 24 Jun 2011 13:22:19 +0200 (CEST) Rio API 0 These errors are printed because your classpath contains a file that specifies the availability of this parser. Please make sure that the file(s) called /META-INF/services/org.openrdf.rio.RDFParserFactory only specify the parsers that are available. Thanks for that knowledge! <br/> <br/> I went and looked at my imported files and found the file in the common-1.2.jar file that is published by <a href="https://github.com/joshsh/sesametools">https://github.com/joshsh/sesametools</a> <br/> <br/> I am using that package for its rdf-json parser and writer, and didn't realise that it was including other parser regitry entries that it doesn't provide. I have filed a bug with that project to remove the unnecessary files. <br/> <br/> It is a very neat way of publishing this information by the way!
