This exception occur when you are using JAXB to marshal a java object (collection type) to xml format. The stack trace looks like this:
Exception in thread "main" javax.xml.bind.JAXBException: class java.util.ArrayList nor any of its super class is known to this context. at com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl.getBeanInfo(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.XMLSerializer.childAsRoot(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.write(Unknown Source) at com.sun.xml.internal.bind.v2.runtime.MarshallerImpl.marshal(Unknown Source) at javax.xml.bind.helpers.AbstractMarshallerImpl.marshal(Unknown Source) at com.howtodoinjava.jaxb.examples.list.TestEmployeeMarshing.main(TestEmployeeMarshing.java:58)
Reason
The above exception occurs because JAXB always expects a @XmlRootElement annotation on the entity, it gets to marshal. This is mandatory and can not be skipped. This @XmlRootElement annotation is required to get meta data from root element of XML marshalled from java object.
ArrayList class OR any java collection class does not have any JAXB annotations on it. Due to this JAXB is unable to parse any such java objects and raises this error.
Solution : Create wrapper class
This is recommended approach because it gives you flexibility to add/remove fields in future e.g. size attribute.
@XmlRootElement(name = "employees")
@XmlAccessorType (XmlAccessType.FIELD)
public class Employees
{
@XmlElement(name = "employee")
private List<Employee> employees = null;
public List<Employee> getEmployees() {
return employees;
}
public void setEmployees(List<Employee> employees) {
this.employees = employees;
}
}
Now you can use this class as below:
static Employees employees = new Employees();
static
{
employees.setEmployees(new ArrayList<Employee>());
Employee emp1 = new Employee();
emp1.setId(1);
emp1.setFirstName("Lokesh");
emp1.setLastName("Gupta");
emp1.setIncome(100.0);
Employee emp2 = new Employee();
emp2.setId(2);
emp2.setFirstName("John");
emp2.setLastName("Mclane");
emp2.setIncome(200.0);
employees.getEmployees().add(emp1);
employees.getEmployees().add(emp2);
}
private static void marshalingExample() throws JAXBException
{
JAXBContext jaxbContext = JAXBContext.newInstance(Employees.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
jaxbMarshaller.marshal(employees, System.out);
}
Output:
<employees>
<employee>
<id>1</id>
<firstName>Lokesh</firstName>
<lastName>Gupta</lastName>
<income>100.0</income>
</employee>
<employee>
<id>2</id>
<firstName>John</firstName>
<lastName>Mclane</lastName>
<income>200.0</income>
</employee>
</employees>

Happy Learning !!
Please note that I am uncertain of the «Found in version» field
above. I’m using Glassfish v1 UR1 P01, so please correct my selection
if I’m incorrect.
I am also uncertain about the subcomponent field. wsimport was my
best guess.
I have written an object called NanonationDictionary that is roughly
a Map, intending this object to be a return type from web service operations.
(I have done this to work around the normal HashMap not working.) My
NanonationDictionary class seems to work fine.
Sometimes I also want to return a List of NanonationDictionary, and this can
also work just fine.
However, if I have a service with an operation that returns List (and it
contains a NanonationDictionary) then I must have some other operation
in that service class that returns a NanonationDictionary.
If no such other operation exists, I get the following exception at runtime,
when the service operation is invoked:
wsimport successful

This error message happens either because your ProfileDto class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class) to make processable by JAXB.,I had this error because I registered the wrong class in this line of code:,JAXBException occurred : class
com.octory.ws.dto.ProfileDto nor any

This is recommended approach because it gives you flexibility to add/remove fields in future e.g. size attribute.
@XmlRootElement(name = "employees")
@XmlAccessorType (XmlAccessType.FIELD)
public class Employees
{
@XmlElement(name = "employee")
private List<Employee> employees = null;
public List<Employee> getEmployees() {
return employees;
}
public void setEmployees(List<Employee> employees) {
this.employees = employees;
}
}
Now you can use this class as below:
static Employees employees = new Employees();
static
{
employees.setEmployees(new ArrayList<Employee>());
Employee emp1 = new Employee();
emp1.setId(1);
emp1.setFirstName("Lokesh");
emp1.setLastName("Gupta");
emp1.setIncome(100.0);
Employee emp2 = new Employee();
emp2.setId(2);
emp2.setFirstName("John");
emp2.setLastName("Mclane");
emp2.setIncome(200.0);
employees.getEmployees().add(emp1);
employees.getEmployees().add(emp2);
}
private static void marshalingExample() throws JAXBException
{
JAXBContext jaxbContext = JAXBContext.newInstance(Employees.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
jaxbMarshaller.marshal(employees, System.out);
}
Output:
<employees>
<employee>
<id>1</id>
<firstName>Lokesh</firstName>
<lastName>Gupta</lastName>
<income>100.0</income>
</employee>
<employee>
<id>2</id>

As of spring-projects/[email protected], the JAXB annotations have been removed and should no longer cause this issue,I have the same «jaxbexception», and thank @Lance-Drane ,who solves it.,You can access the data through a browser as well as CURL if you change all GetMapping annotations to something like this:,Sidenote: My IDE (IntelliJ) also wants to add imports for linkTo and methodOn, while I cannot find imports for these in rest/src/main/java/payroll/EmployeeController.java.

Could not marshal [Resources { content: [Resource { content: Employee(id=1, name=Bilbo Baggins, role=burglar), links: [<http://localhost:8080/employees/1>;rel="self", <http://localhost:8080/employees>;rel="employees"] },

nested exception is javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.internal.SAXException2: unable to marshal type "org.springframework.hateoas.Resource" as an element because it is not known to this context.]
I am getting above exception, looking for solution, any help will be much appreciated. Found the same issue in some other messages, but they were not working for me. Please see the below code.

You can pass several classes in newInstance
jaxbContext = JAXBContext.newInstance(Snapshots.class, EmployeeConstruction.class);

Trying to marshall an Java object graph to XML in a servlet I get the following apparently well known exception:
22:20:10,140 ERROR [STDERR] javax.xml.bind.MarshalException
22:20:10,140 ERROR [STDERR] — with linked exception:
22:20:10,140 ERROR [STDERR] [javax.xml.bind.JAXBException: class YY.XXX.printservice.domain.EmployeeDetails nor any of its super class is known to this context.]
(Note: I renamed the package name.)
When I try google for this problem I get hits galore.
But with the solutions and hints offered — for example the use of @XmlSeeAlso — I still wasn’t able to solve the problem…
The strange thing about this is also that it works when the marshalling is done by a standalone client.
These are the two value classes involved:
1. class Report:
{code}
@XmlRootElement(name=»report»)
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso(EmployeeDetails.class)
public class Report implements Serializable {
@XmlElement(name=»employee», type=YY.XXXX.printservice.domain.EmployeeDetails.class)
private List<EmployeeDetails> employeeDetails;
public Report(){
}
public Report(List<EmployeeDetails> employeeDetails) {
this.employeeDetails = employeeDetails;
}
public List<EmployeeDetails> getEmployeeDetails() {
return employeeDetails;
}
public void setEmployeeDetails(List<EmployeeDetails> employeeDetails) {
this.employeeDetails = employeeDetails;
}
}
{code}
2. class EmployeeDetails:
{code}
@XmlType(
propOrder = {
«employeeId»
, «firstName»
, «lastName»
, «departmentName»
, «jobTitle»
, «salary»
}
)
@XmlAccessorType(XmlAccessType.FIELD)
public class EmployeeDetails implements Serializable {
private Long employeeId;
private String firstName;
private String lastName;
private String departmentName;
private String jobTitle;
private Float salary;
public EmployeeDetails(){
}
public EmployeeDetails(Long employeeId
, String firstName
, String lastName
, String departmentName
, String jobTitle
, Float salary) {
this.employeeId = employeeId;
this.firstName = firstName;
this.lastName = lastName;
this.departmentName = departmentName;
this.jobTitle = jobTitle;
this.salary = salary;
}
public Long getEmployeeId() {
return employeeId;
}
public void setEmployeeId(Long employeeId) {
this.employeeId = employeeId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getDepartmentName() {
return departmentName;
}
public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;
}
public String getJobTitle() {
return jobTitle;
}
public void setJobTitle(String jobTitle) {
this.jobTitle = jobTitle;
}
public Float getSalary() {
return salary;
}
public void setSalary(Float salary) {
this.salary = salary;
}
}
{code}
The relevant parts of the servlet:
{code}
public final class PrintServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
@EJB(mappedName=»EmployeeBean/local»)
private EmployeeLocal employeeBean;
private static JAXBContext jaxbContext = null;
private FopFactory fopFactory = FopFactory.newInstance();
private TransformerFactory transformerFactory = TransformerFactory.newInstance();
private DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
public PrintServlet() {
super();
}
public void init() throws ServletException {
try {
jaxbContext = JAXBContext.newInstance( new Class[] {Report.class});
}
catch (JAXBException exception) {
exception.printStackTrace();
throw new ServletException( exception.fillInStackTrace() );
}
}
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String content = «application/x-java-serialized-object»;
response.setContentType(content);
try {
List<EmployeeDetails> employeeDetailsList = employeeBean.getDetailsForAllEmployees();
Report report = new Report();
report.setEmployeeDetails(employeeDetailsList);
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
jaxbContext.createMarshaller().marshal(report, document);
….
{code}

Thus the two JAXBContext instances do not only know the same data types, but they also know the two relevant custom classes Report and EmployeeDetails.
But the similarity continues: Outputting the schema known to both JAXBContext instances shows that they are also the same.

Why is it that the marshalling in the servlet throws an Exception and the marshalling in the standalone client gives a result like this:
{code:xml}
<?xml version=»1.0″ encoding=»UTF-8″ standalone=»yes»?>
