2. Re: servlet cannot work after upgrade from 4.02 to 4.03
tissues Oct 19, 2005 8:33 PM (in response to tissues)all the servlet program cannot work and show above error message after upgrade from 4.02 to 4.03
Is any extra configure need to do for 4.0.3?
I cannot invoke any servlet program at 4.0.3 while it was work fine on 4.0.2 or older version...
Thanks...

3. Re: servlet cannot work after upgrade from 4.02 to 4.03
starksm64 Oct 19, 2005 10:41 PM (in response to tissues)The invoker servlet is not compatible with the RunAsListener because it bypasses the normal servlet creation process. You need to comment out the RunAsListener in the jbossweb-tomcat55.sar/context.xml descriptor:
<!-- The contents of this file will be loaded for each web application --> <Context cookies="true" crossContext="true"> <!-- Session persistence is disable by default. To enable for all web apps set the pathname to a non-empty value: <Manager pathname="SESSIONS.ser" /> To enable session persistence for a single web app, add a WEB-INF/context.xml --> <Manager pathname="" /> <!-- Install an InstanceListener to handle the establishment of the run-as role for servlet init/destroy events. <InstanceListener>org.jboss.web.tomcat.security.RunAsListener</InstanceListener> --> </Context>
