while starting my weblogic(having my app war file containing logback-classic-1.0.1.jar),i am getting below exception.Any suggestion ?
This type of exception occurs when your classpath does not contain this class.
If the jar's class is in your classpath, you pay attention to what classpath application you using at runtime. Indeed, often, classpath can be overwritten during runtime, or simply you can use a different one (for example, in a startup script).
