transformation - Error in using gdal java binding -


i using java binding of gdal project set of coordinate points utm lat/log using coordinatetransformation class of gdal. have written code follows:

    spatialreference outm = new spatialreference();     spatialreference olatlog = new spatialreference();      outm.setprojcs("utm 44/ wgs84");     outm.setwellknowngeogcs("wgs84");     outm.setutm(44, 1);      olatlog = outm.clonegeogcs();      double[] arr = new double[2];     arr[0]=10;     arr[1]=10;      double x = arr[0] , y = arr[1];      coordinatetransformation transform = new coordinatetransformation(outm,olatlog);      transform.transformpoint(arr);      system.out.println("before:"+x+" "+y+"\nafter:"+arr[0]+" "+arr[1]);

but when run in main function, following error: exception in thread "main" java.lang.unsatisfiedlinkerror: 

org.gdal.osr.osrjni.new_spatialreference__swig_1()j     @ org.gdal.osr.osrjni.new_spatialreference__swig_1(native method)     @ org.gdal.osr.spatialreference.<init>(spatialreference.java:117)     @ controller.crsconvertergdal.main(crsconvertergdal.java:8)

does know how can fixed? thanks,

i tried executing source code , got error

native library load failed. java.lang.unsatisfiedlinkerror: no osrjni in java.library.path

so adding gdal.jar in project build path not sufficient executing program. there external native library dependencies.

check out link,https://trac.osgeo.org/gdal/ticket/3598. here mentioned,

the gdaljni.dll, ogrjni.dll, gdalconstjni.dll , osrjni.dll gdal17.dll , other dependant libraries must in path.

and in order generate these dll windows os , include them in build path, steps mentioned here, https://trac.osgeo.org/gdal/wiki/gdalogrinjavabuildinstructions

i have not tried steps mentioned in above link, seem straight forward. if face issues let know, try , see.

hope helps.
