Thanks Sergey. Your comment helped a lot.
But I am having issues in managing derived objects with namespace.
This is the test case.
@Test
public void testWriteReadDerivedNamespace() throws Exception {
JSONProvider<Base1> provider = new JSONProvider<Base1>();
provider.setMarshallAsJaxbElement(true);
provider.setUnmarshallAsJaxbElement(true);
Map<String, String> namespaceMap = new HashMap<String, String>();
namespaceMap.put("http://derivedtest";, "derivedtestnamespace");
provider.setNamespaceMap(namespaceMap);
List<String> classnames = new ArrayList<String>();
classnames.add(Base1.class.getName());
classnames.add(Derived1.class.getName());
provider.setJaxbElementClassNames(classnames);
Map<String, String> jaxbEleClassMap = new HashMap<String, String>();
jaxbEleClassMap.put(Base1.class.getName(), "{http://derivedtest
}bas");
jaxbEleClassMap.put(Derived1.class.getName(), "{http://derivedtest
}der1");
provider.setJaxbElementClassMap(jaxbEleClassMap);
Base1 b = new Derived1("base", "derived");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
provider.writeTo(b, Base1.class, Base1.class,
new Annotation[0], MediaType.APPLICATION_JSON_TYPE,
new MetadataMap<String, Object>(), bos);
readBase(bos.toString());
}
private void readBase(String data) throws Exception {
JSONProvider<Base1> provider = new JSONProvider<Base1>();
provider.setMarshallAsJaxbElement(true);
provider.setUnmarshallAsJaxbElement(true);
Map<String, String> namespaceMap = new HashMap<String, String>();
namespaceMap.put("http://derivedtest";, "derivedtestnamespace");
provider.setNamespaceMap(namespaceMap);
List<String> classnames = new ArrayList<String>();
classnames.add(Base1.class.getName());
classnames.add(Derived1.class.getName());
provider.setJaxbElementClassNames(classnames);
Map<String, String> jaxbEleClassMap = new HashMap<String, String>();
jaxbEleClassMap.put(Base1.class.getName(), "{http://derivedtest
}basenamespace");
jaxbEleClassMap.put(Derived1.class.getName(), "{http://derivedtest
}dernamespace");
provider.setJaxbElementClassMap(jaxbEleClassMap);
ByteArrayInputStream is = new ByteArrayInputStream(data.getBytes());
Base1 base = provider.readFrom(
Base1.class, Base1.class,
new Annotation[0], MediaType.APPLICATION_JSON_TYPE,
new MetadataMap<String, String>(), is);
assertEquals("base", base.getBase1Field());
}
The Bean class are:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Base1"
, namespace = "http://derivedtest";
)
@XmlSeeAlso({Derived1.class })
public class Base1 {
protected String base1Field;
Base1() { }
Base1(String base) {
base1Field = base;
}
public String getBase1Field() {
return base1Field;
}
public void setBase1Field(String value) {
this.base1Field = value;
}
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Derived1"
, namespace = "http://derivedtest";
)
public class Derived1
extends Base1 {
protected String derived1Field;
Derived1() { }
public Derived1(String base, String derived) {
super(base);
derived1Field = derived;
}
public String getDerived1Field() {
return derived1Field;
}
public void setDerived1Field(String value) {
this.derived1Field = value;
}
}
provider.writeTo serialize as follows.
{"derivedtestnamespace.bas":{"@xsi.type":"ns2
:Derived1","base1Field":"base","derived1Field":"derived"}}
During unmarsalling it is throwing the following exception:
javax.ws.rs.WebApplicationException:
java.lang.IllegalArgumentException:*prefix ns2 is not bound to a
namespace

I don't how namespace ns2 jumps in.
Please help.
Thanks,
