Hi, This is the start of the stacktrace I get when I try the Tomcat (v 4.0-b-5)CookieExample servlet. Worked fine on Tomcat 3.2 win98/win2k, broke when I upgraded to 4.0. Has anyone else seen/fixed this before I start digging? A Servlet Exception Has Occurred java.lang.NullPointerException at CookieExample.doGet(CookieExample.java:53) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) Regards John Sisk _________________________________________________________ Do You Yahoo!?
