[gdal-dev] Cannot load Java GDAL native library in web application with error in link library?

[yuchan]

for anyone has same problem as me, you can see the answer here:
http://fahdshariff.blogspot.de/2011/08/changing-java-library-path-at-runtime.html
for the option 2 with the change directly in code and you need to put the
gdal library folder as input.

Option 2: Add path to usr_paths
Instead of having to re-evaluate the entire java.library.path and
sun.boot.library.path as in Option 1, you can instead append your path to
the usr_paths array. This is shown in the following code:
/**
* Adds the specified path to the java library path
*
* @param pathToAdd the path to add
* @throws Exception
*/
public static void addLibraryPath(String pathToAdd) throws Exception{
    final Field usrPathsField =
ClassLoader.class.getDeclaredField("usr_paths");
    usrPathsField.setAccessible(true);
 
    //get array of paths
    final String[] paths = (String[])usrPathsField.get(null);
 
    //check if the path to add is already present
    for(String path : paths) {
        if(path.equals(pathToAdd)) {
            return;
        }
    }
 
    //add the new path
    final String[] newPaths = Arrays.copyOf(paths, paths.length + 1);
    newPaths[newPaths.length-1] = pathToAdd;
    usrPathsField.set(null, newPaths);
}
