Java: jaxb Generircs
- by Mac
How can I get jaxb to bind to my Vector? I cannot seem to get it to bind a Vector that contains generics as it complains that it cannot recognize my class "shape" or any of its subtypes.. "[javax.xml.bind.JAXBException: class shape.shape nor any of its super class is known to this context.]"?
import java.util.Vector;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlAccessorType(XmlAccessType.NONE)
@XmlRootElement(name = "XVector")
public class XVector<shape> {
private Vector<shape> q;
public XVector() {}
@XmlElement(name = "q")
public Vector<shape> getVector() {
return q;
}
public void setVector(Vector<shape> q) {
this.q = q;
}
}
I get the following errors:
javax.xml.bind.MarshalException
- with linked exception:
[javax.xml.bind.JAXBException: class shape.Rectangle nor any of its super class is known to this context.]

public void saveFile(File filename) {
try {
FileOutputStream fout = new FileOutputStream(filename);
objs.setVector(objVec);
JAXBContext context = JAXBContext.newInstance(XVector.class);
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(objs, fout);
fout.close();
} catch (JAXBException e) {
e.printStackTrace ();
} catch (Exception ex) {
JOptionPane.showMessageDialog(this, ex.toString(), "Error", JOptionPane.ERROR_MESSAGE);
}
}
