- the jai and imageio jars have to be within the same bundle, lets say javax.media.jai_imageio
- tested also with separate bundles for jai and imageio but got several exceptions when loading images like arcgrid.asc files :
- in addition to the base bundle I created native fragments for the following platforms, each fragment contains a platform filter:
- the bundles net.refractions.udig.jai and its fragment net.refractions.udig.jai.macosx would not be required anymore (which copies the jars into folder resolved by a specific strategy
- the JRE that is shipped with udig releases doesn't have to have the jai/imageio jars in the extension folder anymore
- the bundle net.refractions.udig.libs got and additional requirement that will be reexported : javax.media.jai_imageio
1. How can I check, whether the native libraries are loaded correctly (API calls, something like isNativSupportAvailable())
2. Where can I find additional data sets to test, whether everything works correctly with JAI/imageio
I tested with mentioned asc files and tiff files -> everything looks fine (on mac) but it was not possible to load *.sid and *.ecw files -> Add data wizard doesn't finish, no exceptions, Any suggestions here?
3. Could anybody test if I created the pull request the native libs on linux 32/64 bit, I can test on mac os and win32/64 bit with 32 bit runtime
4. Is there a wiki page that describes how to setup the JRE with gdal binaries for native support?
