Now, I know the server https://forums.alfresco.com/comment/45014 has the backing bean. I put a System.out.println statement in the constructor to prove it. When I point my browser to the .jsf page, I can see my output from error 500 the constructor of the backing bean on my Tomcat console spew. That tells me it has the bean. The getAllAgents method is the first method on the .jsp. And yes, I've deleted the application directory and .war file from Tomcat each time I deployed this bugger, which is numbering close to a million. Other, simpler pages display okay. This one error 500 javax.faces.el.evaluationexception is a little more challenging in that it deals with Lists. Why can't it load? From the config file:

I have been trying to get Alfresco running for 5 days now. I am not sure what else to do…I installed Alfresco-Labs-3Stable-Linux-x86-Install on Ubuntu 9.04 server set-up with repository pacakages for LAMP Server and Tomcat Server (used options at install). My Ubuntu Server is installed on a virtual Machine using VMWare. I followed the instructions located at http://wiki.alfresco.com/wiki/Installing_Alfresco_Lab_3_Stable_on_Ubuntu_8.10I kept getting an error that Apache could not find either alfresco or share. I determined issue was coming from the base install of Tomcat6. Since it was already running on port 8080, the scripts (alfresco.sh and virtual_alf.sh) could not start the service.I used /etc/init.d/tomcat6 shutdown to stop base service. I was then able to use alfresco.sh and virtual_alf.sh to start the Alfresco installed version of tomcat.I started this service at 11:05pm. I opened my browser (Mozilla Firefox) and navigated to http://hostname:8080/alfresco and http://hostname:8080/share (in second tab after a few minutes.) At 6:45am the following morning, neither page had painted, and the browser indicated it was still attempting to load/access the sight.I had to go to the paying job, so I left the browser running. I arrived home after work (8:00pm), both pages had painted. The url for “alfresco" (http://hostname:8080/alfresco) had changed to http://hostname:8080/alfresco/faces/jsp/dashboards/container.jsp displaying following error:Syste
