private static Logger logger = Logger.getLogger(MessageService.class);

@GET

@Produces(MediaType.APPLICATION_JSON)
public List<MessageModel> getMessage(Integer subCatId) {
  return "something";
}

Have been struggling to find the cause of this error. Any help would be appreciated.

A:

Looks like you have 2 colliding dependencies:
<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>jsr311-api</artifactId>
    <version>1.1.1</version>
</dependency>

And:
<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0</version>
    <scope>provided</scope>
</dependency>

Try to remove 1.1.1 version.
