Hello, 

I've been working on installing Armstrong 1.0 in place of the beta version I 
was using before. I upgraded my prerequisites as needed. The configuration 
and UI build seemed to go fine using the las.xml and categories.xml files I 
had used with the older version.

However whenever I try to create an output product, I get the error "HTTP 
Status 404 - Servlet action is not available." 

http://www.dataintheclassroom.org:8080/las/ProductServer.do

Initially I was seeing "Parsing error processing resource 
path /WEB-INF/struts-config.xml" in my catalina.out so I applied the fix that 
Roland suggested on Oct 17.
http://www.pmel.noaa.gov/maillists/tmap/las_users/fu_2007/msg00066.html

That error has gone away, but I'm still getting "Servlet action not available" 
in the browser. I'm not very experienced troubleshooting java, so I'm hoping 
this is a simple problem that someone will recognize. I'm not  I've confirmed 
that Armstrong is using the proper Java installation on the server. 

I appreciate any insights. The latest catalina.out log is attached below.

Thanks in advance,
Todd
