UPnP library for Java [closed]

Question

Is there a library for implementing service discovery and publishing via UPnP?

(I am trying to find some alternatives to JmDNS that while protocol-wise worked fine for our purposes, was highly unstable as a library, having an unacceptably bad tendency for deadlocking itself.)

You can also try: sourceforge.net/projects/cgupnpjava – Senatorial

I think we fixed all the deadlocks we ever found in JmDNS, but it has far bigger problems than that, e.g. it doesn't work at all on some systems. – Witling

@Roland : Can u just tell me what exactly u r about to do? i need help on discovering the UPnP device in android.. I want to make app which my android device serves as a medium which can be able to stream media from internet and then make available to UPnP device..Any help on this.. – Suchlike

Thanks i was looking forward for this only...thanks – Suchlike

We need it for integration with a 3rd party POS system that uses UPnP for comunication and negotiation. I can't really help you out in your particular case (fwiw - I find UPnP to be an extremely ugly protocol) – Sweetscented

I have made an app with this library (market.android.com/details?id=com.mikebevz.upnp) but the library throws NulPointerException on Android 3.0+ devices. Does anyone see this problem? – Iveyivie

The library is no longer maintained so probably not a good choice anymore – Gloriagloriana

You could also try ohNet which includes Java bindings and control point / device stacks under a BSD license.

interesting... but i can not found how can i get my gateway UDN with it. is it possible to do that? – Genisia

@IMAnis_tn use CpDeviceListUpnpDeviceType("upnp.org", "InternetGatewayDevice", 1, listener). 'listener' will be called back each time such a device is found. Use the getUdn() function to retrieve the device udn. You could also use CpDeviceListUpnpServiceType if you want to search for a particular service type. – Inpour

@IMAnis_tn it'd also be worth having a look at the Control Point overview on the project wiki for details on how to initialise the library – Inpour

Looks like it is not 100% Java. – Antiphonary

@ThorbjørnRavnAndersen that's correct. Its a C++ library with Java wrappers for all public APIs. The C++ code can be built for Android, Windows, Mac & Linux so can be trivially deployed to platforms most likely to host Java. Ports to other OSes would be possible too. – Inpour

@simonc, hmm why aren't there some getting-started samples – Otten

@Otten the overview docs cover this – Inpour
