Java APIs

Respected Sir/ Madam,
I am doing my project in Network Security using java. I have to transfer the files from server to the client. Each transferred file should have some of the access privileges such as read, write and exeucte. If the transferred file is a word document means then automatically the client should open Microsoft word and if the file is having Read Permission alone then the save, Save As, cut,copy, paste options in the MS - Word should be disabled. This is similar for all the files that i have transferred. That is if the transferred file is excel, audio, video,txt file the corresponding application should be opened properly. How could I acheive this. If the file is having write permission then if the user clicks the save option then the contents of the file should be saved in the server machine not in the client machine, Could we achieve this???? Can anyone help me regarding this? Please give me your views about this query?
