java.lang.LinkageError: ClassCastException:attempting to castjar: javax.ws.rs-api-2.0.1.jar

问题

The error message you provided indicates a java.lang.LinkageError with a ClassCastException while attempting to cast a class. This issue seems to be related to a conflict with the Jersey (JAX-RS) library versions in your project.

To resolve this issue, you should ensure that you have consistent and compatible versions of Jersey libraries throughout your project. In your pom.xml file, you have a mix of Jersey 1.x and Jersey 2.x dependencies, which could be causing the problem.

Here are some steps to consider:

  1. Remove Jersey 1.x dependencies from your pom.xml if you are not using them. Specifically, the dependencies related to com.sun.jersey and javax.ws.rs.

  2. Ensure that you have only one version of Jersey (preferably Jersey 2.x) in your dependencies, and make sure it's compatible with Java 8 and Tomcat 8.

  3. Check for any other conflicting dependencies in your project that might be causing this issue.

  4. Rebuild and redeploy your project to Tomcat after making these changes.

By ensuring consistency in your Jersey dependencies, you should be able to resolve this ClassCastException issue.

I have faced the same error with my code and could resolve by using jersey dependency version 2.34
