How to create Java objects from XML tags that reference each other?

I have XML that has tags corresponding to the three types of Java objects that will be created from XML. Objects have the form:

A
- static Map<String, A>
- String name
- String aInfo1
- String aInfo2

B
- static Map<String, B>
- String name
- String bInfo1
- String bInfo2

C
- A aObject
- B bObject

Now, in my XML, I define a list of tags for objects A and B, and then I define tags for objects C that refer to objects A and B using the name field. I have two requirements:

  • populates static maps in A and B when reading objects A and B from XML. Maps will contain a mapping of A.name to A and B.name to B, respectively.
  • populate C objects by reading A.name and B.name from the XML tag, and then using the maps defined in objects A and B.

     </map>

For an object C referencing A and B, you can read the following tutorial on object reference: http://x-stream.imtqy.com/graphs.html . If this does not suit you, you can always easily create another class to read the necessary information from XML using XStream, for example

public class CInfo {
    public String aName;
    public String bName
}

And create instances of C using CInfo. Since you already have a name for the instance card A and B, this will be trivial.
