Is the DocumentProcessor thread capable?

Question

Hi everyone,
I'd like to know if the DocumentProcessor is thread capable?
I'm using the BI Publisher 10.1.3.2 APIs to burst mutiple input files at a time. If I keep my program single threaded, everything goes fines. But if I spawn a couple of threads at the same time, it sometimes goes fine or I sometimes get a bunch of :
[092407_104518081][][EXCEPTION] java.io.FileNotFoundException: null\65.xml
     at oracle.apps.xdo.template.pdf.util.FormUtil.createURL(Unknown ...
[092407_104518097][][EXCEPTION] java.lang.NullPointerException
     at oracle.xml.parser.v2.XMLParser.parse(XMLParser.java:200)...
[092407_104518097][][EXCEPTION] Error while generating the Document...
[092407_104518097][][EXCEPTION] java.io.FileNotFoundException: null\67.xml (Le chemin d'accès spécifié est introuvable)...
etc etc...
If I wait a couple of milliseconds before spawning each thread, then everything goes fine. Is there a way that each thread can Interfere with another thread? Is the document processor doing some I/O actions involving the same temporary documents or whatsoever?
I've tried to specify a different temporary folder for each thread but I still get those errors. My threads are using the same control file, the same RTF templates but different xml inputs files. Every delivery is a PDF file written in the same folder but with a unique name.
Where am I doing something wrong?!
Thank you,
Guillaume

Thanks for your reply,
Actually, all the exceptions are being thrown by the document processor. The code is as simple as this:
import java.util.Properties;
import oracle.apps.xdo.batch.DocumentProcessor;
public class Burst extends Thread {
private String m_FichierControle = null;
private String m_FichierDonnees = null;
private String m_DossierTemporaire = null;
private ProprieteBean[] m_ProprietesUtilisateur = null;
public Burst(String FichierControle, String FichierDonnees,
String DossierTemporaire,
ProprieteBean[] ProprietesUtilisateur) {
m_FichierControle = FichierControle;
m_FichierDonnees = FichierDonnees;
m_DossierTemporaire = DossierTemporaire;
m_ProprietesUtilisateur = ProprietesUtilisateur;
this.start();
public void run() {
long start = System.currentTimeMillis();
try {
DocumentProcessor dp =
new DocumentProcessor(m_FichierControle, m_FichierDonnees,
m_DossierTemporaire);
if (m_ProprietesUtilisateur != null &&
m_ProprietesUtilisateur.length > 0) {
Properties prop = new Properties();
for (int j = 0; j < m_ProprietesUtilisateur.length; j++) {
prop.put("user-variable:" +
m_ProprietesUtilisateur[j].getAttribut(),
m_ProprietesUtilisateur[j].getValeur());
dp.setConfig(prop);
dp.process();
} catch (Exception e) {
System.err.println(e);
System.out.println("Temps d'exécution burst: " +
(System.currentTimeMillis() - start) + " ms.");
I'm running this by calling :
Burst test1 = new Burst(paramsSet1...);
Burst test2 = new Burst(paramsSet2...);
Burst test3 = new Burst(paramsSet3...);
I'm bad at Threading but I don't see why these would interfere with each other. I'm 75% sure its the Document Processor that is kinda locking files when parsing the RTF or whatsoever... Where am I wrong again :( What threading law am I breaking here ;)
Thank you,
