1)I need to write an applet in JDK 1.1 which will access serial port and printer. This applet will run on netscape 4.5 . Are signed applets necessary .. if yes how to do this .. any pointers .. sample code will be helpful.
I had tried example given by at java.sun.com, it throws security exception.
2) To run a signed applet on browser r there any software required on client side other than browser.
3)Are third party digital certificates must for this? (Our clients are known to us since the applet will be run within our organization.)
