The result of:<BR>
<BR>
rootObject.addContent(objectA);<BR>
<BR>
is to set rootObject as the parent of objectA and to add objectA into the content of rootObject such that rootObject.getContent() will return a list that contains an objectA reference within it (rootObject.getContent().indexOf(objectA) will return a 0 or positive value). This assumes that objectA doesn't yet have a parent!<BR>
<BR>
To add ObjectB to ObjectA you must:<BR>
<BR>
objectA.addContent(objectB);<BR>
<BR>
Again objectB must not yet have a parent.<BR>
<BR>
As Per said, you need to build your JDOM from whatever other representation you already have in memory using whatever logic your application needs!<BR>
<BR>
I still don't understand where the problem is, but that's probably because I've no idea what you're really trying to achieve!<BR>

Sorry for not being very clear on what I want to do. I give it another try.
I import an xml file (1). I creat a JDOM tree and retrieve information about parent-child relations since the xml I have does not express that for my objects explicitly. Then I have to create an another xml file (2) that describes the relationship between the objects. I have to create xml (2) to look like this:
<Model>
<RootObject>
<ObjectA>
<ObjectB/>
<ObjectC/>
<ObjectD>
<ObjectE/>
</ObjectD>
</ObjectA>
<RootObject>
</Model>
This describes that parent-child relation in xml. Which is fine. But when I extract the relationship and try to build xml (2) I get a problem with keeping the relations.
I addContent() to rootObject. Like this:
rootObject.addContent(ObjectA);
Will the resulting Element be rootObject+ObjectA.
So how can I then add ObjectB?
Hope it is a little bit more clear :-) Maybe ....

When you add one element (child) to another element (parent),
you create a parent-child relationship. Which parent-child
relationship do you want to be preserved?

You cannot make it recursive! Where are the grand children, and the
grand-grand children, etc?

Not knowing what your'e trying to do, but here are two hints:
1) if youre tree is static, one alternative is to use a bottom-up
approach (although I do not really recommend the coding style):
Element e =
new Element("L1").addContent(
new Element("L2").addContent(
new Element("L3").addContent(
new Element("L4").addContent(
new Element("L5").addContent(
new Element("L6").addContent(
new Element("L7").addContent(
new Element("L8"))))))));
(At least the tree structure is obvious :-))
2) if your tree is dynamic, you must have some representation of it
before
you go off and construct the JDOM tree. This representation must then be
traversed
and the JDOM tree built up along the way.
