I need to build a code where I have to make the content disposition automatically.Means I need to fetch some text fields,some image fields,some sounds and all of the request I have to take with the post request,I can not use the get r开发者_StackOverflow中文版equest. So please say me how can I buld the content disposition in java?

Its kind of unclear. But as far as I understand it I'll try to explain. The post request must be a button,so in that button you define the action of that button. set action on click and in that method try to get all the values,i.e., for text field data use gettext() and so on.
