I'm trying to read some mrsid images, and thought I'd use ImageIO-ext
That's the only way you can achieve that.
The instructions seem simple enough, but no luck. Just to warn you, I've
rarely used any Java apps, so I know nothing! Even worse, I'm using Vista.
I love Vista! (Ok, that was a joke 
).
First question:
"To use these libs, be sure your JAVA_HOME environment variable is properly
configured. "
What exactly does this mean? I assume this means to setup a Windows
Environment variable like this, which I did in the Advanced System Settings,
then got this in a command window with SET:
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_10
That is not entirely correct. You need to set the env var system wise,
otherwise it will be not picked up all the time.
I would also add the bin directory to the PETH env var, which means
that in Advanced System Settings you need to:
1> create and env var for JAVA_HOME as you did
2> add %Java_HOME%\bin to the PATH var (this is to have Java get the
dll from there)
You can do it bi the concatenation char which on windows is semicolo (
; ). Something like
current_path;%JAVA_HOME%\bin
"On Windows: copy the downloaded DLLs to your $JAVA_HOME/bin
Extract gdal_data.zip somewhere on your machine (as an instance
C:/gdal_data).
Set a GDAL_DATA environment variable linking to the directory where you have
stored data contained in gdal_data.zip, making sure the web container
running GeoServer will pick it up.
Ok, did this
have: GDAL_DATA=c:\gdal_data
Same as above, you need to do that from the ASS.
restarted GS, didn't work. Still just getting the usual 5 coverage plugins.
What am I doing wrong?
ImageMosaic / 1.0 Image mosaicking plugin
GeoTIFF / 1.1 Tagged Image File Format with Geographic information
WorldImage / 1.0 A raster file accompanied by a spatial data file
ArcGrid / 1.0 Arc Grid Coverage Format
Gtopo30 / 1.0 Gtopo30 Coverage Format
I think you are using the standard geoserver. As of now (gs 1.7.0)
support for gdal through imageio-ext is still an extension since we
(imageio-ext) were waiting on gdal 1.5.3 to be released (which just
happened ) to start with our release train. This means that soon
we will have an imageio-ext official release and that will be the
trigger to get gdal support shipped by default with GeoServer.
Now what does all this mean to you? It means that you might be using a
standard version of GeoServer which does not contains the Java
counterparts for the dll you installed, hence no gdal based plugin for
you!
Tell me what version of GeoServer you are using and I'll bundle up a
GeoServer for you.
Simone.
Roger
