OC4J (9.0.4) and Spring question

Question

I have a servlet in which I get the request dispatcher for an application that is using Spring and forward control to the Spring application.
ServletContext newContext = servletContext.getContext("/springApp");
RequestDispatcher dispatcher = newContext.getRequestDispatcher("/main.htm");
// Forward the new request
dispatcher.forward(request, response);
Everything works if the application has just been deployed. If OC4J is stopped and then started again, then I get an internal server error from OC4J in the jsp that the SimpleFormController in the Spring application forwards to complaining about a
NoClassDefFoundError : org/springframework/web/servlet/tags/BindStatus
Touching the JSP(to cause a re-compile) or deleting the generated JSPs from
oc4j904\j2ee\home\application-deployments\default\springApp\persistence\_pages directory fixes the problem. Any ideas as to why OC4J cannot find the class on a restart but does on a clean deploy?
Thanks

Answer 1

The 9.0.4 and just released 10.1.2 versions are J2EE 1.3 compatible and implement the Servlet 2.3 specification.
Therefore it'd not be safe to assume the presence of any new behaviours from the 2.4 spec.
