Sorry, the only way I can suggest to do this with the current code is by
actually adding another pack.Subfolder class that extends pack.Folder
and adds nothing. That way you could create a <mapping> for
pack.Subfolder using name="subfolder" that just duplicates everything
from the pack.Folder mapping.

Hi,
I made the first step towards the solution of my problem. I can now
map (the collection of) recursive elements with the following approach:
<mapping class="pack.Folder" extends="pack.Element" name="Folder">
<value field="Name" name="Name"/>
<collection field="Subfolder" usage="optional">
<structure map-as="pack.Folder"/>
</collection>
<value field="Description" name="Description"/>
</mapping>
But one problem remains: How can I change the name of the element for
the subfolders?
What I can map now is:
<Folder>
<Name>/home</Name>
<Folder>
<Name>/home/michi</Name>
<Folder>
<Name>/home/michi/docs</Name>
<Description>Michis Dokumente</Description>
</Folder>
<Description>Michis Home Verzeichnis</Description>
</Folder>
<Description>Home Verzeichnis</Description>
</Folder>
But, what I want to map is the following:
<Folder>
<Name>/home</Name>
<subfolder>
<Name>/home/michi</Name>
<subfolder>
<Name>/home/michi/docs</Name>
<Description>Michis Dokumente</Description>
</subfolder>
<Description>Michis Home Verzeichnis</Description>
</subfolder>
<Description>Home Verzeichnis</Description>
</Folder>
The difference is, that I want to be able to rename the "inside"
Folder element (for instance to "subfolder"). I tried a few ways to
accomplish this task but without success. Maybe someone can help me
with this.
thanks

There shouldn't be any problem with this providing you use a
<mapping> definition for the recursive structure. What you *can't* do
is define it with a <structure> that just references back to itself
(with "label" and "using"). If that's unclear reply back to the list
with a sample of your current binding and we should be able to point
you in the right direction.

Hi,
I use JIBX for a quite complex set of xml files defined by a
schema-like structure. I ran into a problem (StackOverflow) when I
tried to bind a recursive element with the following definition (I
know it is not "real" xml schema):
<xsd:complexType name="Folder">
<xsd:element name="Name" type="xsd:String"/>
<xsd:element name="subfolder" type="Folder" maxOccurs="unbounded"/>
<xsd:element name="Description" type="xsd:String"/>
</xsd:complexType>
I tried a few different ways to bind it without success.
My Question: Is there a way to bind recursive structures like this
one? What I am currently planning to do is writing my own
(de)serializer, what should not be too hard a job. But any "easier"
solution would be welcomed.
thanks
Michael
