I want to create a java page with a Button and a TextBox So that when the user writes the number 1 in the TextBox and then presses the Button It will redirect him to open a pdf file from ex: www.mywebsite / myfile1.pdf When the user writes the number 2 in the TextBox and then presses the Button It will redirect him to open pdf file from www.mywebsite / myfile2.pdf
Thank you
