Todd,

I believe that the problem lies with changes with some of theconfiguration files that happened between the Beta version you haveinstalled and Armstrong 1.0. In particular the productserver.xml filehas a new <ftds> element. I'm not sure how you did your configuration,but here's what I suggest.

Start with a fresh copy of Armstrong 1.0. Run configure with thedefault data sets. Verify everything works. Then integrate yourconfiguration into the installation. You'll have to examine the filesin conf/server and integrate the files from your old site into the filescreated by the configure process using the default installation. Thenrun genLas.pl to install your data sets and restart tomcat to read thenew configuration.

Hello,I've been working on installing Armstrong 1.0 in place of the beta version Iwas using before. I upgraded my prerequisites as needed. The configurationand UI build seemed to go fine using the las.xml and categories.xml files Ihad used with the older version.
However whenever I try to create an output product, I get the error "HTTPStatus 404 - Servlet action is not available."
http://www.dataintheclassroom.org:8080/las/ProductServer.do
Initially I was seeing "Parsing error processing resourcepath /WEB-INF/struts-config.xml" in my catalina.out so I applied the fix thatRoland suggested on Oct 17.

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 hopingthis is a simple problem that someone will recognize. I'm not I've confirmedthat 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
