General file support for WebServer

2008-01-05T11:44:18Z

In order to make the usage of the Device class easier it would be nice to provide all kind of files by the webserver (including icon files like gif,jpg,png ...).

For security reasons, only files in a given subdirectory must be supported and not all files in the applications path!

Standardize logging and debugging

2006-03-23T14:34:17Z

Can you use a standard java class for logging and
debugging instead of: org/cybergarage/util/Debug.java ?

java.util.logging.Logger
-or-
org.apache.log4j.Logger
-or-
org.apache.commons.logging.Log

I would be willing to help out and make some of these
changes.

'DeviceChangeListener' Interface?

2004-09-12T19:25:09Z

Greetings Satoshi -

One feature I have found a handy addition to CLink is a
'DeviceChangeListener' interface. A ControlPoint
application that supports this interface is notified
via callbacks when a device is added or removed by the
ControlPoint base class. Here's the interface:

package org.cybergarage.upnp.device;

import org.cybergarage.upnp.Device;

public interface DeviceChangeListener
{
public void deviceAdded( Device dev );
public void deviceRemoved( Device dev );
}

The modification consists of a few extra lines of code in
ControlPoint.java, and the new 'DeviceChangeListener' class
in cybergararge/upnp/device. Attached is a zip file with
the files (started with CLink1.5 version of
ControlPoint.java)

P.S. Feel free to pick another name besides
'DeviceChangeListener' if you decide to include the
feature and have a better name - it was the first thing
that popped into my head!

Also, I noticed that the CLink source has a mixture of
Windows/Unix line endings - some lines end with <CR><LF>,
and some with just a <LF>. Not a problem - just noticed
it since my emacs editor under UNIX displays the <CR>
symbols at the end of only some of the lines.

Handle missing 'Content-Length' header field?

2004-03-13T19:19:53Z

Greetings Skonno...

A friend of mine got a Play@TV device recently
(www.playattv.com) and I tried interacting with it via
CLink. It didn't quite work, and
after a little snooping, I discovered that the device
was not putting a 'Content-Length' header in it's HTTP
responses. A little suprising, given that the device
uses Intel's UPNP MicroStack - maybe the PlayTV guys
got over-enthusiastic 'customizing' it? :)

Anyway, I managed to get it to work by putting a couple
of kludges in the CLink code. Basically I modified the
HTTPPacket.getContentLength() so it returned -1 (as
opposed to 0) if no Content-Length header was found,
and then I modified HTTPPacket.set( InputStream in) so
that if there was no Content-Length header in an
incoming HTTP response (first line starts with HTTP),
the reader code just reads until it hits EOF or
64Kbytes. I told you it was a kludge! :)

I don't know if you want to formally support this
device and similarly broken devices - in my opinion
they should fix their stuff (I sent them a note letting
them know). In any event, it might be nice to print a
warning message about the missing Content-Length field
so it's obvious when one has a slightly defective device.

Let me know if you want the source for my hacked-up
workaround - it may do more harm than good!

Support for Sony's UPnP stack

2004-01-16T16:04:57Z

Hi,

I am working with some Sony UPnP applications. Sonys
adressing scheme for services and actions is different to
the others (like Intels or Atinavs) but still conform with
the standard (UPnP? Device Architecture v1.0.1 Draft, p.
25 and p.27). Sony uses the following addressing scheme
in the devices root document:

As base address it uses a hostname with an additional
path in the URI, like

<URLBase>http://hostname/mediaserver</URLBase>

All service specific URIs (like SCPDURL, controlURL and
eventSubURL) are relative to the URLBase like

<controlURL>/musicServer/actionsURI</controlURL>

As consequence the total address would be the
concatenation of both URIs which is not supported by the
Cyberlink stack yet. It would be nice to have that
support.

I fixed it manualy by altering the org.cyberlink.upnp.
control.ControlRequest.setRequestHost() method. Maybe
there is a better way to include the support. Attached
there is my ControlRequest.java class as example.

Cheers, Thomas

Custom UPnPError replies

2003-12-05T15:53:16Z

Hi,

it would be nice to set a custom error code maybe
combined with an error message in case an action
couldn't be processed right. A method like

action.setUPnPError(int code, String message)

would be nice. The set of Error Code and Error Message
could be checked if the implementation of the
ActionListener returns a "false". In case it is set, the
reply could be changed according to the error message.

What do you think?

Regards, Thomas

Support for Simple Network Management Protocol?

2003-08-30T21:23:24Z

Would you like to offer a SMNP interface for UPnP?
Is there a
virtual SNMP "device" or service available?

CORBA integration for UPnP

2003-08-30T21:13:31Z

Can CORBA objects be transformed into virtual
"devices"?
Would you like to offer an adaptor for Universal
Plug and Play like the software
"http://soap2corba.sourceforge.net/" can be a similar
gateway?

How do you think about to publish the
interfaces of your class library in OMG-IDL?
