Flash : I have merged a XML server for Flash that I have created for the testing last year, into a package of CyberLink for Java to control UPnP devices by remote or create the user interface by Flash.

I have created some user interfaces using Swing or native user interfaces such as Carbon and Gtk, but Flash might be a good solution to crate the user interface on any platforms.

I would like to create the UPnP/AV media server for iTunes. I want to study Objective-C and Cocoa because I know only the old development style, Carbon. However I might create the user interface using Flash.

Retemo UI : To read XRT Protocol v2.2 in more detail, I noticed that I have to send the REQUEST command at first when the XRT connection is established, and the connection is disconnected when the connection takes more than 5 seconds.

To follow the specification, I could connect my RemoteUI Client with a sample RemoteUI server of Intel Authoring Tools for UPnP Technologies (Build 1825) normally :-)

I have created a initial framework of the RemoteUI server and client, but I have to decide the concept what image I want to display to the RemoteUI clients in the near future. I would like to use the framework to control remote devices by mobile or home devices, but it might not be good solution ....

UPnP IGD : I am creating a sample application for the Internet gateway devices using CyberLink for Java to check a problem about the UPnP device this week.

Using the sample application, I could post some basic controls such as GetExternalIPAddress and AddPortMapping to BEFSR41 V2 normally. I will add more functions to the sample application, but you can get the latest source codes from the Subversion if you want.

Retemo UI : I am studying the specification with Intel NMPR v2.1 Guidelines and XRT Protocol v2.2 to develop the future devices.

I am developing the client and server using CyberLink for Java and Intel Authoring Tools for UPnP Technologies (Build 1825) that has sample implementations of the client and the server.

I can create the client and the server basically, but I have some problem about the XRT protocol. The sample server of Intel returns a rectangle drawing command whenever it is received any XRT commands from the client. My client can connect the specified URI of the Intel's server and send XRT commands normally, but the Intel's server ignores the XRT commands. I tried to connect the URI with TLS protocol using JSEE, but the client became no response when it sent any XRT commands using the OutputStream.

I found the the server and the client of Intel send all XRT commands only on TLS protocol. To solve the problem, I have to check the XRT specification and TLS protocol in more detail.
