关于Jackrabbit的ObjectPersistenceManager的问题

[MBlue]

我自己写了一个小程序，PersistenceManager配置的是org.apache.jackrabbit.core.state.obj.ObjectPersistenceManager

repository和workspace都是文件系统，我用的windows
我添加了一个node并成功上传了一个文件，然后尝试获取该文件，也成功了。

但是问题是我尝试在我的文件系统中招我所添加的节点和上传的文件，竟然找不到。我想知道ObjectPersistenceManager把他们存到那里去了。
谢谢。以下是代码：
protected void doPost(HttpServletRequest request,HttpServletResponse response) throws IOException{
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
Session session=null;
FileOutputStream fo=null;
InputStream stream = null;
if (isMultipart){
try {

Repository repository = new TransientRepository();
session = repository.login(new SimpleCredentials("user",
"password".toCharArray()));
Workspace ws = session.getWorkspace();
System.out.println(ws.getName());
FileItemFactory factory = new DiskFileItemFactory();
// DiskFileUpload fu = new DiskFileUpload();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// ServletFileUpload upload = new ServletFileUpload();

// upload.setHeaderEncoding("utf-8");

// Parse the request
List items = upload.parseRequest(request);

Iterator iter = items.iterator();

while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();

if (!item.isFormField()) {
Node root = session.getRootNode();
System.out.println(root.getName());
Node node =null;
if (!root.hasNode("UploadedFile")) {
node = root.addNode("UploadedFile");
} else {
node = root.getNode("UploadedFile");
}
NodeIterator ni = root.getNodes();
while(ni.hasNext()){
System.out.println( ((Node)ni.next()).getName() );
}
// Property pt = node.getProperty(item.getName().substring(item.getName().lastIndexOf("\\")+1));
// fo = new FileOutputStream("D:\\test.txt");
// stream=pt.getStream();
// int bytesRead = 0;
// byte[] buffer = new byte[8192];
// while ( (bytesRead = stream.read(buffer, 0, 8192)) != -1) {
// fo.write(buffer, 0, bytesRead);
// }
node.setProperty(item.getName().substring(item.getName().lastIndexOf("\\")+1), item.getInputStream());
// node.save();
session.save();
}
}
} catch(Exception ex){
ex.printStackTrace();
} finally {
session.logout();
// fo.flush();
// fo.close();
// stream.close();
}

没有人用过吗？
