com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector not found --- while using Swagger

Question

my first post on SO and expecting good stuff in return :-)

I have developed a small java restful services app and integrated with Swagger. I have @Controller -> @Service -> @Repository architecture. I have deployed on Glassfish (4.1.1), when I use Chrome's 'Advanced Rest Client', I am able to perfectly send and receive rest calls (GET/POST etc), but when I use Swagger, it throws the following exception 'after Controller returns the correct response'.

I have been struggling with this by changing the maven entry versions, changing the moxy jar, delting felix as suggested in some forums etc, none seem to help.

Here are more details ...

Exception:

  StandardWrapperValve[com.xxx.config.ApplicationConfig]: Servlet.service() for servlet com.xxx.config.ApplicationConfig threw exception
java.lang.ClassNotFoundException: com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector not found by com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider [130]

        Document doc = documentService.getDocument(docId);
        DtoDocument dto = toDto(doc);
        return dto;
    }

        Document doc = getMongoTemplate().findOne(Query.query(Criteria.where("id").is(Id)), Document.class, COLLECTION_NAME);
        return doc;
    }

}

Appreciate if anyone can tell me what exactly is the issue ... its been a frustrating week & am stuck with this, not making any progress.

Answer 1

The stack trace mentions: java.lang.ClassNotFoundException: com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector not found by com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider

and you are excluding the JAXB annotation module:

<exclusion>
   <groupId>com.fasterxml.jackson.module</groupId>
   <artifactId>jackson-module-jaxb-annotations</artifactId>
</exclusion>

The exclusion means a dependency is not resolved, and therefore you'll get the ClassNotFoundException

Answer 2

This worked for me:

Steps: 1-Stop domain

2-Remove content of this folder: Glassfish\glassfish\domains\DOMAIN_NAME\osgi-cache\felix

3-In this folder: C:\Glassfish\glassfish\modules Substitute jackson libraries by the 2.4.4 version:

jackson-module-jaxb-annotations-2.4.4

jackson-jaxrs-json-provider-2.4.4

jackson-jaxrs-base-2.4.4

jackson-databind-2.4.4

jackson-annotations-2.4.4

jackson-core-2.4.4

4-Start domain

I hope it helps :-)
