Re: Where's my image?

[Phil Moses <pbmoses@xxxxxxxx>]

Ben,
I wanted to touch back on the output alias for apache. 

In your config.results file you should have a line similar to the
following:
$LasConfig{fullpath_output} =
'http://ecco-las.ucsd.edu/lasxml-output/LASserver.pl'

The directory "lasxml-output" is the directory which will need to be
aliased out in the apache config with a line similar to the following:

Alias /lasxml-output/
/las/apache/www/org.ecco-group.www/lasxml/server/output/

Is your output directory "/usr/local/las/las/server/output" aliased out
in the httpd.conf file?

Hopefully this helps, I am trying to think of anything that may be
holding you up there.
