Dear Bob,
there are a few options available for JPEG2000 support in GeoServer which depends on which licenses you have (or not have 
) access to.
The best options in terms of performance are Kakadu and ECW, both of them are not free for serving JPEG2000 on the internet using GeoServer ( you can read the licenses on their websites).
A good option is also MrSID which is free but not open source (freeware).
To use MrSID you can follow this instructions:
http://docs.geoserver.org/latest/en/user/data/raster/gdal.html#adding-support-for-ecw-and-mrsid-on-windows
Basically there is an extra step since this is a separate plugin for GDAL, you hence need to place the DLLs/SOs inside a folder and then tell the GeoServer process where this is located by pointing to it the GDAL_DRIVER_PATH environmental variable (see page above).
You might also want to check the GeoServer logs a message should tell you whether or not the GDAL native libs have been located by GeoServer or not.
Let us know how it goes.

I am trying to install the GDAL support for Jpeg2000 on a Geoserver 2.6.x installation. I have been trying to follow these instructions:
http://docs.geoserver.org/latest/en/user/data/raster/gdal.html
I downloaded and installed the following, per the instructions:
Coverage Formats JPEG2k http://geoserver.org/release/stable/, placed in my web-inf folder
The GDAL binaries and msi from here: http://demo.geo-solutions.it/share/github/imageio-ext/releases/1.1.X/1.1.10/native/gdal/windows/MSVC2010/
The GDAL data from here: http://demo.geo-solutions.it/share/github/imageio-ext/releases/1.1.X/1.1.10/native/gdal/
I have a GDAL_DATA environment variable
After restarting GeoServer, I am still not seeing JPEG2000 support. I’ll admit that I am having trouble understanding the instructions, I did the best I could. But I am not able to get JPEG2000 to work. Does anyone have any ideas?
