Java.nio.BufferUnderflowException when send a idoc xml using sapjco3.jar

Question

When I use sapjco3.jar to send a idoc
I have 2 IDOC ,one size is 200kb ,another is 336kb
the first one can send to sap correct, but the bigger one got Exception (java.nio.BufferUnderflowException)
If any thing I have to note when writing java code ? thanks ....

My Code :
JCoDestination destination;
String dest = "BCE";
destination = JCoDestinationManager.getDestination(dest);
IDocRepository iDocRepository = JCoIDoc.getIDocRepository(destination);
String tid = destination.createTID();
IDocFactory iDocFactory = JCoIDoc.getIDocFactory();
IDocXMLProcessor processor = iDocFactory.getIDocXMLProcessor();
IDocDocumentList iDocList = processor.parse(iDocRepository, new BufferedInputStream(new FileInputStream("D:
TXLOG-12964100.xml"));
JCoIDoc.send(iDocList, IDocFactory.IDOC_VERSION_DEFAULT, destination, tid);

hi,
it only works with idoc to idoc scenarios I think
when you send from SAP to SAP through XI
have a look at my weblog:
