Hi all,
I am writing a custom unmarshaller and marshaller for the root element
of a XML / root of an object structure.
I think the jibx binding compiler does not like it when I have two
different classes for the marshaller and unmarshaller. Looks like the
generated class file corresponding to the Unmarshaller replaces the
generated class file relating to the Marshaller.
But If I have the same class to do both marshalling and unmarshalling,
then everything looks fine.
For example:
Case 1 :
Say I have the following mapping definition:
<mapping class="someclass" name="someElement"
marshaller="MyMarshallerClass"
unmarshaller="MyUnmarshallerClass" />
this generates only a class file called
JiBX_dma_bindingMyUnmarshallerClass_0.class, in addition to the other
class files corresponding to stuff defined in the bindings.xml. I had a
look in to the decompiled source and see something like this.
package test;
import org.jibx.runtime.IMarshaller;
import org.jibx.runtime.IUnmarshaller;
import com.MyUnmarshallerClass;
public class JiBX_dma_bindingMyUnmarshallerClass _0 extends
MyUnmarshallerClass
implements IUnmarshaller, IMarshaller
{
public JiBX_dma_bindingOrderUnmarshaller_0()
{
super(null, 0, "RootElementName");
}
}
Case 2 :
When I have the mapping as following:
<mapping class="someclass" name="someElement"
marshaller="MyMarshallerClass"
unmarshaller="MyMarshallerClass" />
Note: here I am using the same class , which acts as both a marshaller
and an unmarshaller, implementing both IUnmarshaller and IMarshaller
interfaces.
In this case, the binding compiler generates only a class file called
JiBX_dma_bindingMyMarshallerClass _0.class. The source of this is:
package test;
import org.jibx.runtime.IMarshaller;
import org.jibx.runtime.IUnmarshaller;
import com.MyMarshallerClass;
public class JiBX_dma_bindingMyMarshallerClass _0 extends
MyMarshallerClass
implements IUnmarshaller, IMarshaller
{
public JiBX_dma_bindingMyMarshallerClass _0()
{
super(null, 0, "RootElementName");
}
}
In case 1, when I try to marshall, I get
Exception in thread "main" java.lang.AbstractMethodError:
com.JiBX_dma_bindingMyUnmarshallerClass
_0.marshal(Ljava/lang/Object;Lorg/jibx/runtime/IMarshallingContext;)V
,, obviously because my unmarshaller class does not define the marshall
method, ,,, . But I did this purposely, since I wanted the marshaller
and unmarshaller code to be in different classes.
Ok. Now the question is : Is it mandatory for both marshaller and
unmarshaller to be the same class, for jibx to work properly.
Thanks in advance for any replies.
