hi,
i am doing an embedded server project using str9. can any one help me how to send an audio file, image and a popup text to the client(PC) using html/jsp loaded in the microcontroller.
You cannot send a file using HTML!
HTML = Hyper-Text Markup Language: it is the "language" used to write web pages - it is not a communication or file-transfer protocol!
I think you mean HTTP = Hyper-Text Transfer Protocol.
This is a standard internet protocol - it has nothing specifically to do with microcontrollers. Therefore any tutorials, books, etc on HTTP - of which there are plenty - should be of use to you.
Here's a good one to get you started:

You should also look at his other "Web Technology Made Really Easy" articles:

You will probably also need a good understanding of TCP/IP:
