Glassfish 4 REST XML Working JSON Error

Question

I have a web service on Glassfish 4.1 that is working properly for XML but not for JSON.

The entity class is:

@XmlRootElement
public class Person implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = -8969081094076790550L;
    Integer id;
    String firstName;
    String lastName;
    String employeeId;

    /**
     * 
     */
    public Person() {
    }

    @Override
    public String toString() {
        return firstName + " " + lastName + " [" + employeeId + "] [id: " + id + "]";
    }
    /**
     * @return the firstName
     */
    public String getFirstName() {
        return this.firstName;
    }
    /**
     * @param firstName the firstName to set
     */
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    /**
     * @return the lastName
     */
    public String getLastName() {
        return this.lastName;
    }
    /**
     * @param lastName the lastName to set
     */
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    /**
     * @return the employeeId
     */
    public String getEmployeeId() {
        return this.employeeId;
    }
    /**
     * @param employeeId the employeeId to set
     */
    public void setEmployeeId(String employeeId) {
        this.employeeId = employeeId;
    }
    /**
     * @return the id
     */
    public Integer getId() {
        return this.id;
    }
    /**
     * @param id the id to set
     */
    public void setId(Integer id) {
        this.id = id;
    }

}

The relevant service code is:

@GET
@Path("xml")
@Produces(MediaType.TEXT_XML)
public Collection<Person> getPeopleXML() {
    return personDao.getAllPeople(); 
}

@GET
@Path("json")
@Produces(MediaType.APPLICATION_JSON)
public Collection<Person> getPeopleJSON() {
    return personDao.getAllPeople(); 
}

The XML call works, and I get:

<people>
 <person>
  <employeeId>2234</employeeId>
  <firstName>Mike</firstName>
  <id>2</id>
  <lastName>Jones</lastName>
 </person>
 <person>
  <employeeId>22314</employeeId>
  <firstName>Joe</firstName>
  <id>4</id>
  <lastName>Smith</lastName>
 </person>
</people>

I get an error with the JSON call:

HTTP Status 500 - Internal Server Error

type Exception report

messageInternal Server Error

descriptionThe server encountered an internal error that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: com/fasterxml/jackson/module/jaxb/JaxbAnnotationIntrospector root cause

Why the error? I have everything I need, I think. I have an ivy file and tried adding all kinds of jackson deps, but nothing seems to work. I cannot tell if I am having version problems when I add jackson to my ivy file since it's included with Glassfish, or what.

Glassfish provides the following:

/d/glassfish4/glassfish/modules/jackson-annotations.jar
/d/glassfish4/glassfish/modules/jackson-core.jar
/d/glassfish4/glassfish/modules/jackson-databind.jar
/d/glassfish4/glassfish/modules/jackson-jaxrs-base.jar
/d/glassfish4/glassfish/modules/jackson-jaxrs-json-provider.jar
/d/glassfish4/glassfish/modules/jersey-media-json-jackson.jar

Answer 1

Here is the solution:

1. Stop Glassfish

2. Delete all of the jackson stuff in the modules directory for Glassfish.

3. Delete the domains/domain1/osgi-cache/felix directory

4. Copy the following files to that directory:

/glassfish/modules/jackson-annotations-2.4.0.jar

/glassfish/modules/jackson-annotations-2.5.0.jar

/glassfish/modules/jackson-core-2.4.2.jar

/glassfish/modules/jackson-core-2.5.4.jar

/glassfish/modules/jackson-databind-2.4.2.jar

/glassfish/modules/jackson-databind-2.5.4.jar

/glassfish/modules/jackson-jaxrs-base-2.5.4.jar

/glassfish/modules/jackson-jaxrs-json-provider-2.5.4.jar

/glassfish/modules/jackson-module-jaxb-annotations-2.4.2.jar

/glassfish/modules/jackson-module-jaxb-annotations-2.5.4.jar

/glassfish/modules/jersey-media-json-jackson.jar

Then it works. Not sure what version the original files for Jackson were, but this works and upgrades your jackson module versions.

Answer 2

I had same problem in which i battled with it for days. The problem is a missing jar file ( jackson-module-jaxb-annotations ) in glashfish 4.1.1. You can download it from this link http://www.java2s.com/Code/Jar/j/Downloadjacksonmodulejaxbannotations212jar.htm or google download jackson module jaxb annotations. Then include it in C:\Program Files\glassfish-4.1.1\glassfish\modules directory. you can rename the jar file by removing the version number. Restart glassfish and redeploy your app. It works for me that way
