问题 I\'ve been getting a very strange error when trying to start a Jersey app on Tomcat. The same code works on other computers.

Any pointers in the right direction will be appreciated.

How do I do this? I use @Path / @GET annotations on my service beans and register them via ResourceConfig#registerClasses . Is there a way to query the Config for all Paths? Update: I register the REST Controllers via @Bean
