hi,
I have installed las.armstrong1.1.1 and it is successfully being deployed to tomcat. But when i send the request for ploting, i mean when i select the variables and select the constraints and click Next.. I am getting the following message
================================================================================================================================
Not Found

The requested URL /las/ProductServer.do was not found on this server.
================================================================================================================================
While going through the forum, one of the user suggest to make change in struts-config.xml.and den stop and restart the server.
But still i am getting the same error.(for more detail about error message)
http://www.pmel.noaa.gov/maillists/tmap/las_users/fu_2007/msg00064.html

I am not getting what should i do, so as to resolve the 404 not found exception.. i also checked the catalina, where i got the following exception on the console..
