Re: Can't happen - classname is null, who added this
Venkatesh-- This message is generated by Tomcat ServletWrapper program. It is trying to load the servlet, but finds that it's class (note: Class not same as Object) is NULL. I sincerely doubt that there is a bug in their program - I would start looking at your CLASSPATH and other ENV variables. Seems to be a common program.

I sincerely doubt that there is a bug in their program - I would start looking at your CLASSPATH and other ENV variables. Seems to be a common program . This does not have to do with classpath OR env vars. It is actually a flaw in class loading. Every time a class is recompiled it generates a new id based on the class definitions and therefore when tomcat tries to instantiate a instance of a class and the serialid has changed since the classdef was loaded the classloadeer believes that it can't find the classdef and throws this message. Once again I am going to mention that people need to stop posting to the list in HTML. If you go back and read the webpage where you signed up for the list one of the guidelines is no meta formats(ie HTML). Some people who use mailviewers such as pine, elm, mail( don't laugh I do actually know individuals who have used mail to read/send mail ), cannot read or will have a difficult time reading HTML messages. I realize no matter how many times I rant about this there will still be people who post in HTML but my objective is to reduce the number of these individuals and while I CAN read HTML messages I don't see the need for that kind of excessive junk here and understand the viewpoint of those who aren't able to read these messages. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
