Re: [las_users] LAS Server Error: javax.servlet.ServletException

Hello,

Fortunately, this is an easy problem to solve. There are several pieces of software that must work together in order for LAS to create a plot of the data. The error you see occurs when the user interface server (the module responsible for putting up pages the user sees to select the data) attempts to contact the product server (the module that actually plots the result). The product server is a collection of CGI-base Perl scripts which run when the URL: http://poseidon-n219.ath.hcmr.gr:8080/las-bin/LASserver.pl is contacted. In order for the Apache server to recognize "las-bin/LASserver.pl" as a CGI script that it can run you need to add some information to the Apache configuration file (usually /etc/httpd/conf/httpd.conf) and force Apache to re-read its configuration files:

Try:
You should add the following lines to your Apache configuration file (:
ScriptAlias /las-bin/ /[The Directory Where Your LAS is Installed]/las/server/
Alias /las-output/ /[The Directory Where Your LAS is Installed]/las/server/output/

All of this assumes that http://poseidon-n219.ath.hcmr.gr:8080/ is the URL of an Apache HTTPD server (and not a Tomcat server). If the server is not an Apache server, you might try configuring Tomcat to run the CGI scripts, but this is an untested and unsupported configuration.

hi everybody,

I installed LAS UI Version 6_5_2_1, along with the COADS climatolgy
dataset that came with it. However, when I try to visualize the dataset,
i get the following error:

You have encountered an unexpected User Interface error! Please click
