Re: java.io.NotSerializableException: java.util.HashMap
I don't know what the relationship is between this error and your JSP, but it looks like your container is trying to serialize the session for some reason. Apparently you have a session attribute which is a HashMap, and it doesn't like that because it can't serialize it. -- Martin Cooper - Original Message - From: Matt Raible [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, August 28, 2001 11:30 AM Subject: java.io.NotSerializableException: java.util.HashMap I am getting the following error on a JSP page that I am using struts taglibs.

Re: java.io.NotSerializableException: java.util.HashMap
I figured it out - I was stuffing hashmaps and rowsets into my ActionForms, and then storing those in the session. Because of the clustering configuration we have in iPlanet, this error was being thrown for the reasons you state. I fixed this my moving any non-serializable components into beans only kept in the request.
