I have a java desktop application, being an executable jar and I need to know the root directory where the jar is running. I have researched several ways and I have not found what I need, I am always seeing models where I inform an X file so it returns me the location of the same and what I need and get the Root of the Executable Jar.
Thank you.
You can use String path = new File(".").getCanonicalPath(); for this.
Solution for what I need:
The only solution that works for me on Linux, Mac and Windows:
public static String getJarContainingFolder(Class aclass) throws Exception {
CodeSource codeSource = aclass.getProtectionDomain().getCodeSource();
File jarFile;
if (codeSource.getLocation() != null) {
jarFile = new File(codeSource.getLocation().toURI());
}
else {
String path = aclass.getResource(aclass.getSimpleName() + ".class").getPath();
String jarFilePath = path.substring(path.indexOf(":") + 1, path.indexOf("!"));
jarFilePath = URLDecoder.decode(jarFilePath, "UTF-8");
jarFile = new File(jarFilePath);
}
return jarFile.getParentFile().getAbsolutePath();
}
