I've be working with the PostableResource (thanks to everyone who replied to my resource 'caching' question - A: bug in JDK) quite a bit, and have been trying to set and get cookies. For example, I want to set a cookie id=23423 in one script and then get the id in a different script. I've created a class CGIApplet (couldn't think of a good name) that extends PostableResource. Its intended purpose is to have a bunch of commonly used methods such as getCookie() and setCookie(). I keep getting a NullPointerException when I call setCookie() in the code below. It seems to come from the addCookie() method of HttpCookieList. Does anyone have any simple code that sets a cookie? // start code ----------------------------------------- package oroad.jigsaw.util; import w3c.www.http.*; import w3c.jigsaw.http.*; import w3c.jigsaw.forms.*; import w3c.jigsaw.html.*; /** * CGIApplet adds some commonly used functions to the web servers * java API.
