I get the following error sometimes when I have let the tomcat running for a
while, but have had little or no activity in the sessions. When I call
session.getAttribute("attributeName"), I get the error:
java.lang.IllegalStateException: getAttribute: Session already invalidated
at
org.apache.tomcat.session.StandardSession.getAttribute(StandardSession.java:503)
at login.SessionController.addSessionManager(SessionController.java:80)
at login.SystemManager.login(SystemManager.java:173)
My question is: why does this happen? Is there a setting in web.xml or
server.xml or elsewhere that I can change so that sessions do not time out /
are not invalidated?
Operating system: Windows 2000
Java version: Java 1.2 with Java Servlet 2.2 and JSP 1.1
Web server: Apache 1_3_22
Servlet engine: Tomcat 3.2.3
Thanks,
