部署到tomcat后的Jersey错误，在Eclipse中可以正常工作

Question

I've lost hours trying to pinpoint this annoying issue. I've created a simple Java app that exposes a few REST services using Jersey.

When debugging the application in Eclipse, using a Tomcat 8 server, everything works fine. I then export the project to a WAR file, deploy it to a real Tomcat 8 server, and when I try to call the REST services, I get the below error. I've checked the obvious things: making sure I'm using the correct Java version on the server, making sure the libraries are included, ... But alas, I'm stuck.

type Exception report

message Servlet.init() for servlet Jersey REST Service threw exception

description The server encountered an internal error that prevented it from fulfilling this request.

Answer 1

I believe this is not because of missing jar.. I believe it is class loading issue. The jersey jars are not being loaded (or) might have been loaded the wrong version. Could you please check the dependencies properly and check for duplicate jars for jersey in your application.

Also Please try by undeploying appliation and deploying again.. This might remove all the classes that were already loaded for taht application and Tomcat might intialize class loading again..

Hope this works...
