Hi,

I am using oracle hibernate spatial with spring framework. I get "com.vividsolutions.jts.geom.Polygon does not have a no-arg default constructor" error when I deploy it to Tomcat.

I believe the no-args constructor error came because the Polygon class does not have a constructor with no arguments, is this correct? If so, is there a workaround?

I've tried many sites to see if there is a solution, without any success. Any idea how to solve this issue?
Appreciate any kind of help.

Here are some of my classes.

entity class that include a geometry column

@Entity
@Table(name = "SPATIALTABLE")

public class Test implements Serializable, Comparable<Test> {
  ...

@Column(name="Loc", columnDefinition="MDSYS.SDO_GEOMETRY", nullable = true)
@Type(type="org.hibernatespatial.GeometryUserType")

   private Polygon location = null;

   public Polygon getLocation() {
        return location;
    }
    public void setLocation(Polygon location) {
        this.location = location;
    }

   // empty constructor
    public Test(){}
...
}

====== The class where I get the error ================
public class TestTarget implements Serializable, Comparable<TestTarget > {
  ...
...

@OneToMany(
            cascade = CascadeType.ALL)
    @org.hibernate.annotations.Cascade({
            org.hibernate.annotations.CascadeType.DELETE_ORPHAN
            })
    @JoinColumn(name = "ID", nullable = false)
    // unidirectional from tableA(one) to TableB (many)
    @org.hibernate.annotations.Sort(
          type = org.hibernate.annotations.SortType.COMPARATOR,
         comparator = com.xx.xx.xx.xx.comparator.SpatialComparator.class
    )
    private SortedSet<Test> spatialP = new TreeSet<Test>();

error trace

Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions

this problem is related to the following location:

Hi,

I see that the exception thrown in a JAXB exception. What is JAXB
doing here? Are you serializing using JAXB? In that case you can't
use the Polygon class because it has no no-arg constructor (a
requirement of JAXB serialization).

If disabling JAXB serialization is no option, you could subclass
Polygon and create a no-arg constructor for this subclassed Polygon.
HS will persist them just like "regular" polygons.

Karel Maesen

Hi Karel,

Thank you.  Unfortunately, I cannot disable JAXB serialization, therefore, I've created a new Polygon class as you suggested and use the new Polygon class in my entity class. I still get the same error. Here is the new polygon class that I created, could you verify if this is correct? If correct, is there any other suggestion you might have to solve this issue?

public class SpatialPolygon extends Polygon implements Serializable {

    public SpatialPolygon() {
       super(null, null, new GeometryFactory());
    }
}

Best Regards

H.

It looks correct to me. If this still doesn't work I guess you have a
problem in your configuration somewhere. In any case, it looks like a
Spring/JAXB problem rather than a Hibernate Spatial problem.
