I am trying to use BindingGenerator to automate xml serialization needs.
Consider the following Java classes:
public class SomeClass {
public String text;
}
public class ParentClass {
public String name;
public SomeClass[] data;
}
public class ChildClass extends ParentClass{
public String type;
}
Binding Generator command (jibxtools-beta2):
java -cp
c:\apps\jibx\lib\jibx-genbinding.jar;c:\apps\jibx\lib\jibx-bind.jar;c:\apps\jibx\lib\jibx-extras.jar;c:\apps\jibx\lib\jibx-run.jar;.
org.jibx.binding.BindingGenerator -v -a ParentClass ChildClass SomeClass
Generated Binding:
<?xml version="1.0" encoding="UTF-8"?>
<binding forwards="false" value-style="attribute">
<mapping class="ChildClass" name="child-class">
<value style="element" name="type" field="type" usage="optional"/>
<structure map-as="ParentClass" name="parent-class"></structure>
</mapping>
<mapping class="SomeClass" name="some-class">
<value style="element" name="text" field="text" usage="optional"/>
</mapping>
<mapping abstract="true" class="ParentClass">
<value style="element" name="name" field="name" usage="optional"/>
<structure field="data" usage="optional"
marshaller="org.jibx.extras.TypedArrayMapper"
unmarshaller="org.jibx.extras.TypedArrayMapper"></structure>
</mapping>
</binding>
1. Marshalling test (works ok):
Java Code:
IBindingFactory bfact = BindingDirectory.getFactory(ChildClass.class);
ChildClass cc = new ChildClass();
cc.name = "rob";
cc.type = "java";
SomeClass sc = new SomeClass();
sc.text = "hello";
SomeClass[] scArray = {sc};
cc.data = scArray;
IMarshallingContext mctx = bfact.createMarshallingContext();
mctx.marshalDocument(cc, "UTF-8", null, new
FileOutputStream("C:\\child.xml"));
child.xml:
<?xml version="1.0" encoding="UTF-8"?>
<child-class>
<type>java</type>
<parent-class>
<name>rob</name>
<some-class>
<text>hello</text>
</some-class>
</parent-class>
</child-class>
2. Finally, unmarshalling test (fails)
Java Code:
IBindingFactory bfact = BindingDirectory.getFactory(ChildClass.class);
IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
ChildClass cc = (ChildClass)uctx.unmarshalDocument(new
FileInputStream("C:\\child.xml"), null);
Exception message: Expected "parent-class" end tag, found "some-class" start
tag (line 1, col 110)
-------
In my application I do not care about the xml lay-out, only using xml
binding as a ser/deser mechanism, so any automatically generated binding
that can do the job would be acceptable. Is this kind of situation supposed
to be handled by the BindingGenerator tool? The documentation seems to
indicate yes. (Arrays of complex type) If not, please let me know what
modifications to above binding would fix this issue.
Thanks.
