I need the ability to be able to display ECW and JPEG2000 format files within MapServer via a Community Mapbuilder client which sends WMS requests for the images to MapServer

[John Mitchell]

Hi Frank,

Thanks for the information.  I had a couple of questions:

You said below:
"
I am using the "standalone" FWTools binaries for linux
(http://fwtools.maptools.org).  In my Apache cgi-bin directory I have
the script mapserv_landsat which looks like this:

-----------------------
#!/bin/sh

export MS_MAPFILE=/home/warmerda/maps/landsat.map
. /opt/FWTools-1.0.0a2/fwtools_env.sh
exec /opt/FWTools-1.0.0a2/bin/mapserv "$*"
"

How would the above be revised on a windows system?  The exec statement  I
would replace the /opt with /program files since FWTools is within the
"program files" folder on windows.  What about the
. /opt/FWTools-1.0.0a2/fwtools_env.sh statement?  I don't see anything
called fwtools_env.sh within the FWTools folder.  What is #!/bin/sh is this
a linux statement?

Thanks,

John J. Mitchell
