That just means that when I restart the server, I lose client web session data, right? That's not a problem. The full stack trace? It's quite big.

RE: NotSerializableException: StandardSessionFacade
The exception says that the class that can't be serialized is StandardSessionFacade, which is an internal Tomcat class. That's what's confusing me. If it was a class in my code, I would know what to hunt for. Deleting work folder causes problem to go away. However, it will come back. Thanks for the response.

RE: Confusing Tomcat Error: "SEVERE: Error listenerStart"
That worked! I can't imagine what the issue was, but now that it's working smoothly, it's not worth investigating further. Thanks!

Confusing Tomcat Error: "SEVERE: Error listenerStart"
I am writing a web app in Struts. This was working perfectly until I did an uinstall/reinstall of Apache Tomcat 6.0.14 along with the new RC2 of NetBeans 6.0. Now, when I try to run my web app, I get a generic Tomcat error screen: "type Status report message /myapp/ description The requested resource (/myapp/) is not available." Looking through the Tomcat log in NetBeans I see: Nov 26, 2007 1:14:14 AM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 834 ms Nov 26, 2007 1:14:14 AM org.apache.catalina.core.StandardService start INFO: Starting service Catalina Nov 26, 2007 1:14:14 AM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/6.0.14 Nov 26, 2007 1:14:15 AM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart Nov 26, 2007 1:14:15 AM org.apache.catalina.core.StandardContext start SEVERE: Context [/myapp] startup failed due to previous errors Nov 26, 2007 1:14:15 AM org.apache.coyote.http11.Http11Protocol start What does "Error listenerStart" mean and how do I correct that? I am completely stumped. I don't know what else to try or do. Thanks in advance for any replies!
