Unmarshalling with Castor problem

Question

Hello everyone, i have run into a small problem with unmarshalling. Lets say my xml is something like this:
    <Client>
      <Name>a</Name>
      <Something>b</Something>
   </Client>Then everything works, i unmarshal it into a Client Object.
public class Client{
   //getters and setters
}Also i have a mapping, but now if my XML is something like this:
<Book>
   <Page1>
      <Client>
            <Name>a</Name>
            <Something>b</Something>
      </Client>
   </Page1>
</Book>Then what would the mapping be and how do i get the Client object out of it. I tried creating a class for every element.
like
public class Book{
   getBook(){
      //return the book object
}Then
public class Page{
   getPage(){
   //return the page
}So to get the client object i first unmarshalled the Book object, then i did Book.getPage().getClient().getName(); And then i got Nullpointer exception. How do i parse documents like that?
Thanks

Answer 1

here is the weird thing though...in my debugconsole,
I can see the value of source, cuz the content of my
XML file is in the source, but the
parser.parse(source) is called, the content of my
source is NULL...and I think that is why I amgetting
null on my service result every time...I'm not sure what you mean here. You are saying that
you can see the source in a variable (???) and then in
another variable it's null or what?sorry...My bad....no...
parser.parse(InputSource source)...does that sound more clear???
You know how you can see the stack in debug console, what i saw before the Parser.parse(InputSource source) called is
source->characterStream:java.io.reader->str: <xml version='1.2'><name>moe</name><last name>zoe</lasname>...
HOwever, after the Parser.parse(InputSource source) is called, i inspected the stack again, i got
source->characterStream:java.io.reader->str: NULL
that is why i suspect that i got a null serviceResult on my return...
any ideas?? how that happened?? many thanks...
