[SOLVED] MessageBodyWriter not found for media type=application/json – Check Simple 1 Min Solution!

Solution

MessageBodyWriter not found for media type=application/json : this error occurs, because you have missing jersey-media-json-jackson dependency.

To resolve the issue please add the required library to your project. Because Maven and Gradle are two the most popular build automation tools I provide the dependency entry for each one.

Maven

To add the missing dependency just go to the Maven Repository and choose appropriate version or copy past the following code:

<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-json-jackson</artifactId>
  <version>2.32</version>
</dependency>

Gradle Version

When you are using Gradle you can choose the newest Gradle version. Check the link to find the newest one. When I was writing this post it was the v7.4.2.

...
compile group: 'org.glassfish.jersey.media', name: 'jersey-media-json-jackson', version: '2.32'
...

Select Version

Please verify which version you should add to your project. You can check the available version in Central Maven Repository.

Summary

If we use third party libraries, we often encounter the problem of incompatibility of libraries. When we change / raise the version of one library, it may turn out that it no longer contains a built-in dependency. Then, unfortunately, we have to find the missing library and attach it ourselves.

Maven Dependency Tree

In the process of finding the missing dependency, we can use the dependency tree command:

mvn dependency:tree

The snippet from execution the above column looks like the following code:
