Thanks, Mika. I tried this servlet in Tomcat 4.0.1:
http://localhost:8080/examples/servlet/SessionExample and it works in 4.0.1 UNTIL I press the "URL encoded" link. Then I get the exact same error message as I've been reporting. Also, typing in the "Name of Session..." and pressing "Submit Query" also generates the same error. Kind of supports the theory that the way 4.0.1. loads the jar files has changed. Now to find out how to fix it... -Richard >Session in use: >From the jsps, >NumberGuess, Snoop, ErrorPage (after submitting the form), Carts (after >submitting) (I did stop testing here) >From the servlets only the session example. > >Mika -- To unsubscribe: <mailto:[EMAIL PROTECTED]> For additional commands: <mailto:[EMAIL PROTECTED]> Troubles with the list: <mailto:[EMAIL PROTECTED]>
