http - WebDAV 与 J2ME

Question

有没有办法将 WebDAV 与 J2ME 一起使用(一些库或手动编码)？

我试过:
- javax.microedition.io.HttpConnection , 但那里不支持“SEARCH”方法
- javax.microedition.io.SocketConnection与 Http request - 没有任何回应
也许我的代码或 HTTP header 有问题:

    String response = "";
    String query = "<?xml version='1.0'?> " 
            + "<g:searchrequest xmlns:g='DAV:'> "
            + "<g:sql> "
            + "SELECT 'DAV:displayname' "
            + "FROM 'http://exchangeserver.com/Public/' "
            + "</g:sql> "
            + "</g:searchrequest> ";
    String len = String.valueOf(query.length());
    SocketConnection hc = (SocketConnection) Connector
            .open("socket://exchangeserver.com:8080");
    DataOutputStream dout = 
            new DataOutputStream(hc.openOutputStream());
    DataInputStream din = new DataInputStream(hc.openInputStream());
    String userPass = "username" + ":" + "password";
    byte[] encoded = 
            Base64OutputStream.encode(userPass.getBytes(), 0,
            userPass.length(), false, false);
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    String request = "SEARCH /Public/ HTTP/1.1\r\n"
            +"Content-Type:text/xml\r\nContent-Length:"
            + len
            + "\r\nAuthorization:Basic "
            + new String(encoded)
            + "\r\n\r\n";
    bos.write(request.getBytes());
    bos.write(query.getBytes());
    dout.write(bos.toByteArray());
    dout.flush();
    dout.close();
    byte[] bs = new byte[900];
    din.readFully(bs);
    bos = new ByteArrayOutputStream();
    bos.write(bs);
    din.close();
    hc.close();
    response = bos.toString();

“没有返回”是什么意思？没有响应体？没有状态码？

我建议跟踪“电线”上发生的事情...

更新:您是否尝试过添加主机 header ？
