ws greenhorn search for ws

Hi to all,

I am new in ws, but I did develope app with ws; my one app, where I have two app: one was acting like server(it has a ws which comunicate with database), and the other one was acting like a client (it was called ws operations from the server app, and make output with jsp).

And that was for study, and get first info about ws.

Now, I want to have real action; I want to call someones ws, and build my one app on that data (like previously client discribed). So, can somebody tell me, how and where can I found various offered ws with description on how can I used it, and am I have to paid for some ws usage, or what?

I dont get it, how it is going in the real world?

I have read that there is somewhere placed some UDDI register with all the ws in the world, I can I reach and search for it, and use some ws from there, which I like?

Please help,
your ws greenhorn,
Marko
