java.lang.NoClassDefFoundError: jakarta/ws/rs/core/MultivaluedMap

Question

I updated my project to Java 17/Wildfly 27/Keycloak 19 and I get the error:

java.lang.NoClassDefFoundError: jakarta/ws/rs/core/MultivaluedMap

The library Maven: jakarta.ws.rs-api is added in the library of the project via Maven: jakarta.ws.rs:jakarta.ws.rs-api:3.1.0

Does somebody know why this happens?

Answer 1

WildFly (and other JEE / Jakarta EE containers) provide their own Java EE / Jakarta EE classes (servlet API, JAX-RS, JPA, etc.). If you bundle them in your application, these classes will be not be used by WildFly. Even if the class files are identical, the classes in your application are not the same as the provided classes - they have different class loaders. Class equality does not just use the fully qualified class name, it also uses the class loader. As a result, you will most likely get a class mismatch. You didn't show the full stack trace, but this is a likely cause of it.

Mark these dependencies as provided , that should usually solve the issue. You will also have to do something in your shade plugin if they still get included.

The same goes for the RESTEasy dependencies, although that's specific to WildFly / JBoss.

Deleted.idea and reimported everything and now it works
