Hi, I wrote an osgi bundle using logback for logging, I can run it with Eclipse 3.4.2, but I cann't run it outside the IDE. The other bundles are ok. Please reply if possible. ============================================================== D:\osgi_proj\equinox1>java -jar plugins/org.eclipse.osgi_3.4.3.R34x_v20081215-10 30.jar -console -clean osgi> start logging...
