osgi support
by André Kullmann 12 Apr '10

12 Apr '10

Hi, I want to use slf4j in Eclipse RCP Projects. My idea is to replace Activator.getDefault().getLog().log( new Status( IStatus.INFO, Activator.PLUGIN_ID, msg ) ); into class My { static Logger logger = LoggerFactory.getLogger(My.class); something() { logger.info(msg); } } But there is a problem, I need the Bundle to use the eclipse logging. It is possible to get the Bundle from the class objects. But the ILoggerFactory interface has only a getLogger( String ) method :-( And the LoggerFactory.getLogger( Class ) methods calls getLogger( c.getName ). I think it should be possible to log the Bundle in osgi containers. Is there any solution ? My idea, create an interface ILoggerFactory2 extends ILoggerFactory { Logger getLogger( Class c ); } Regrads, André -- _____________________________________________________ André Kullmann Otto Group · GroupTechnologyPartner - Dresden (GTP) Anwendungsentwickler · Touchpoints und Kunde · FI-IM-TK _______________________________________________ GroupTechnologyPartner - Dresden · Freiberger Straße 35 · 01067 Dresden Telefon +49 (0) 351 497 23 185 · Fax +49 (0) 351 497 23 119 andre.kullmann(a)osp-dd.de · www.ottogroup.com _______________________________________________ AG Dresden, HRB 2475 Geschäftsführer: Dr. Thomas Tribius, Martin Mildner
