Whoops - guess I should have tried compiling that before I posted it,
eh? I changed the HashSet to an ArrayList and made some other
modifications to your "Person" class so I could focus on the
back-reference problem; I guess I forgot to unmake them before I copied
the solution into my e-mail.
Anyway, what I was really trying to direct you to the post-set
attribute; that will solve your problem of maintaining a "back
reference" to the person's employer, which I believe was the question in
your original post. I just ran a new compile using your original Person
class, and a (simpler) collection mapping of:
<collection name=3D"employees" field=3D"employees"
usage=3D"optional" =
/>
And got your test.xml to unmarshal correctly using the unmodified
(except for the addition of the postSet handler) Person class.

Subject: [jibx-users] Re: Mapping bi-directional association
Hi,
I have tried adding 'add-method' attribute to the binding file as you=20
suggested. However, I believe that the add-method specified here is
the=20
method for the collection. However, the addEmployee method resides
in=20
the Person class, not in the collection - in this case, HashSet
class.=20
So there is an error when running the binding compiler as follow:
Error: add-method addEmployee not found in class java.util.HashSet
for=20
collection element at (line 43, col 5, in Campaign/jibx-binding.xml)
Regards,
Vairoj
Take a look at the "post-set" binding attribute
(http://jibx.sourceforge.net/tutorial/binding-extend.html):
Add this to your binding file:
<mapping name=3D3D"person" class=3D3D"com.package.Person" =3D
post-set=3D3D"postSet">
<value name=3D3D"name" field=3D3D"name" />
<collection name=3D3D"employees" add-method=3D3D"addEmployee"
item-type=3D3D"Person" usage=3D3D"optional" />
</mapping>
And this to Person:
public void postSet( IUnmarshallingContext ctx )
{
if ( ctx.getStackDepth( ) > 1 )
{
setEmployer( ( Person ) ctx.getStackObject( 1 ) );
}
}
The trick is to get at the unmarshalling context and go up one level
in
the stack to the parent (but make sure to check the stack depth as
shown
above and make sure that you're dealing with a collection element!).

Hi all,=20
=20
The POJO that I want to unmarshal XML into contains additional fields
that I want to populate with fixed values. When I try something like:=20
=20
<mapping name=3D"SCANDTN" ordered=3D"false" class=3D"O_x_class"
pre-set=3D"clear_All">
<value name=3D"version" field=3D"version_num" =
style=3D"attribute"
usage=3D"optional"/>
<value name=3D"dummy1" field=3D"eyecatcher" usage=3D"optional"
default=3D"XMLReply"/>
...
<value name=3D"MSGID" field=3D"message_id" usage=3D"optional"/>
...
</mapping>
=20
where the 'dummy1' field is one of these fields (and 'MSGID' is a real,
expected XML tag), the field (in this case 'eyecatcher') gets set to
null and not the default that I want of 'XMLReply'.
=20
If I change the 'ordered' field to 'true' in <mapping> then in this case
'eyecatcher' does get set to 'XMLReply' which is what I want.
=20
Is this expected behavior? Is there a way to have an unordered set of
XML tags and unmarshall them with default values (as I have no control
over order of the XML tags the sender is creating)??
=20
Thanks for any assistance.

Hi,=20
I can't seem to access the JiBX CVS repository via anonymous login any
longer. It worked fine up until a few days ago. Anyone else with
similar difficulty?

Hi,
The getOutputStream() method only worked for writer's based on
StreamWriterBase -- this did not account for the GenericXMLWriter which,
heh, uses a Writer and thus does not output to a _stream_. So, here's a
revised take on the idea being able to output XML content directly to a
writer.
* Created IRawXMLWriter interface to expose direct write methods;
added it to XMLWriterNamespaceBase which also implements IXMLWriter. =20
* added implementations to GenericXMLWriter and StreamWriterBase. =20
It works for my limited use case - my custom marshaller is able to emit
pre-serialized XML content directly into another documents stream. It
also shields existing users of the IXMLWriter interface from anything to
do with this change.
Here's a simple example of what it would look like (assume 'xml' has
been previously populated): =20
IXMLWriter writer =3D ctx.getXmlWriter();
IRawXMLWriter rawWriter =3D (IRawXMLWriter)writer;
rawWriter.writeRawMarkup(xml); =20
Other code snippets below. It ain't pretty, but it can be very useful.
Any questions, queries, or comments? Is this worthy of inclusion into
JiBX?
