How can I find out what category a product belongs to?

Basically, when a user inputs a product name (such as "iPhone 3g"), I would like to know the parent categories of that item (such as Electronics / Mobile phones). Is there a web api (ie. for ebay, amazon etc.) or any other way to figure out that information? | 0 | [

<ProjectName.ProjectUI sucks as a name for my Netbeans java OS X app.

What property in Netbeans to I need to change to set the name of my java swing app in the OS X menubar and dock? I found info.plist, but changing @PROJECTNAMEASIDENTIFIEER@ in multiple keys here had no effect.

Starteam 2005 COM API

Has anyone worked with the StarTeam COM API (Specifically, intergrating with C#).
I need to write a helper function that returns a directory structure out of Starteam, but all I've been able to retrieve using this API has been a list of views.
Has anyone else tried this? | 0 | [

streaming wav files

I have a server that sends data via a socket, the data is a wav 'file'. I can easily write the data to disk and then play it in WMP, but I have no idea how I can play it as I read it from the socket. Is it possible?
Bonus question: how would I do it if the stream was in mp3 or other format?
