how can I send my client data to Server

hi,
I think I need your help. I want to know how to develop a unity3d network application.
Do you know how can I send my client data to Server and receive the server’s respond??How can I use the Java Server in my unity project?I can not find the information about these.

thanks!

Use the WWW class to request a one time information bundle to or from a server. You can also use theWWWForm class to specify what data you are sending to the server.

Use the NetworkView Component to continuously sync data across multiple clients and/or servers. Here is the documentation on how to create and use networked Unity Applications.

    -Hope this helped <("<)(^"^)(>")>
