Agreed! its *remotely* possible that this is a Classloader error ..system classloader and app classloader both attempting to load different classes This sort of thing shows up in weblogic/glassfish and websphere app servers If you dont have it ..take a look at downloading the class here http://www.jarfinder.com/index.php/java/info/com.opensymphony.xwork.spring.SpringObjectFactory If you're using 2.1.6 Struts I vote for placing xwork 2.1.2.jar in Webapp/WEB-INF/lib
also.. clean off $TOMCAT_HOME/work folder Martin ______________________________________________ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.
