Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: text/html - in Resteasy
Solution 1
(For those who find the question, working with quarkus)
Using this setup routine:
mvn io.quarkus:quarkus-maven-plugin:0.16.1:create -DprojectGroupId=com.sample -DprojectArtifactId=hello-quarkus -DclassName="com.sample.DemoEndpoint" -Dpath="/persons"
To fix the issue described here, I had to add this dependency.
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-resteasy-jsonb</artifactId>
</dependency>
here is my full pom.xml after I added the above dependency. Again, 99% of the below pom.xml came from the mvn command above.

Solution 2
Try to add particular version of serializer
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson-provider</artifactId>
<version>${resteasy.version}</version>
</dependency>
Solution 3
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
adding those annotations solved my issue.
Solution 4
For me it was about trying to serialize the array to XML. If you would like that it would need a wrapper class like this for movies:
@XmlRootElement(name = "movies")
@XmlAccessorType(XmlAccessType.FIELD)
public class Movies
{
@XmlElement(name = "movie")
private List<Movie> movies;
public List<Movie> getMovies() {
return movies;
}
public void setMovies(List<Movie> movies) {
this.movies = movies;
}
}
This way it can be serialized under the root object.

I am developing RESTEasy Example. In this example I am using all latest dependencies and deploying om tomcat 8.x version. I can successfully deploy the application but when I am launching the url: http://localhost:8080/RESTfulExample/rest/restwebservice/list, I see following errors are coming. Please guide what is going wrong here.
