IncompatibleClassChangeError When Deploying JAX-RS Application to Tomcat

Question

When I am running my web project from Eclipse on Tomcat 8 with JDK 8 everything works flawlessly, but once I build this project and deploy the WAR to Tomcat 8 on the server

Answer 1

Looks like it's a problem with dependency versions

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-json</artifactId>
    <version>1.17.1</version>
</dependency>

The above should match the same version as all your other Jersey dependencies. So just change it to 1.19.
