[logback-user] ServletContainerInitializer cannot be found by ch.qos.logback.classic_1.4.8 (in OSGi application)

Hello everybody, In my OSGi application, I use *ch.qos.logback.classic* (1.4.8) for logging. For this reason I have included, among others, the bundle ch.qos.logback.classic_1.4.8. However, this leads to the following error message: *java.lang.ClassNotFoundException: jakarta.servlet.ServletContainerInitializer cannot be found by ch.qos.logback.classic_1.4.8* I get this error even when I have started the bundle jakarta.servlet-api_6.0.0 (containing jakarta.servlet.ServletContainerInitializer). How should I proceed to solve this problem? Best, Benno
