I`m trying to import jcurses library to IntelliJ but get an error. File -> Project Structure -> Modules -> import jar file.
Then in code:
import jcurses.widgets.Window;
class main {
public static void main(String[] args){
Window win = new Window(800, 600, true, "test");
win.setVisible(true);
}
Exception in thread "main" java.lang.ExceptionInInitializerError
at jcurses.system.InputChar.<clinit>(InputChar.java:25)
at jcurses.widgets.Window.<clinit>(Window.java:209)
at main.main(main.java:7)
Caused by: java.lang.RuntimeException: couldn't find jcurses library
at jcurses.system.Toolkit.getLibraryPath(Toolkit.java:121)
at jcurses.system.Toolkit.<clinit>(Toolkit.java:37)
Could someone point out where is my mistake?
Thanks in advance!
The answer is that dll must be in the same directory as jar file. Thanks to everyone!
Libray download url
https://sourceforge.net/projects/javacurses/files/javacurses/0.9.5/
The path of the library is in the root directory of the project
dynamically add the library
import java.io.File;
import java.lang.reflect.Field;
import java.util.Arrays;
public class LoadLibrary {
public static void main(String cor[]) throws Exception {
// Cargando librerias necesarias
loadLibraryJCourses();
}
public static void loadLibraryJCourses() throws Exception{
loadDynamicLibrary(new File("lib/bin/jcourses/").getAbsolutePath(),"libjcurses64");
}
private 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);
}
private static void loadDynamicLibrary(String pathLibraryDirectory, String libraryName) throws Exception{
File pathLibraryFile = new File(pathLibraryDirectory);
addLibraryPath(pathLibraryFile.getAbsolutePath());
System.loadLibrary(libraryName);
}
}
