Hi,
You just don´t call the endDocument() method and the OutputStream isn´t closed, maintain the outstream open and marshall again, and again, how many objects you have.
the method call sequence is this :
mctx.startDocument();
marshall()
if(end)
mctx.endDocument();
This was made inside a Writer, i don´t know what is you class structure, but i hope this will help.
cheers

Hello all,
Does anybody know how can I marshal a huge set of objects, which I get in
chunks into ONE output file.
My problem is that I'm running out of memory if I attempt to collect all
objects that need to be marchaled at once.
What I need to do is to get chunks of results in , say chunks of 100,000
objects and as I get them have JiBX output them into a file
I have a working mapping that does what it needs to do, but it will create a
COMPLETE XML file with all ROOT tags for every chunk of results I pass to
JiBX.
I've noticed that there seems to be a way to do what I need:
There are methods startDocument and endDocument on IMarshallingContext
object.
public void marshalDocument(java.lang.Object root,
java.lang.String enc,
java.lang.Boolean alone,
java.io.Writer outw)
throws JiBXException
Marshal document from root object to writer. The effect of this method
is the same as the sequence of a call to startDocument( java.lang.String,
java.lang.Boolean), a call to marshal the root object using this context,
and finally a call to endDocument().
But what is the method I need to call that would just marshal the chunks of
results without closing the document..
Basically I need this
1. Output enclosing tag: <Securities>
2. In chunks marshal <Security> objects themselves.. It'll have chunks of
"Collection" of 100,000 objects each chunk.
3. Output closing final tag </Securities>
4. And close the output file at this moment.
What kind of mappings I need for that? What methods and in which sequence to
call?
Thanks to all in advance.
Dmitry.
