Adapt this example: How to extract Java resources from JAR and zip archive
Or try this code:
Extract the Contents of ZIP/JAR Files Programmatically
Suppose
jarFile
is the jar/zip file to be extracted.destDir
is the path where it will be extracted:java.util.jar.JarFile jar = new java.util.jar.JarFile(jarFile); java.util.Enumeration enumEntries = jar.entries(); while (enumEntries.hasMoreElements()) { java.util.jar.JarEntry file = (java.util.jar.JarEntry) enumEntries.nextElement(); java.io.File f = new java.io.File(destDir + java.io.File.separator + file.getName()); if (file.isDirectory()) { // if its a directory, create it f.mkdir(); continue; } java.io.InputStream is = jar.getInputStream(file); // get the input stream java.io.FileOutputStream fos = new java.io.FileOutputStream(f); while (is.available() > 0) { // write contents of 'is' to 'fos' fos.write(is.read()); } fos.close(); is.close(); } jar.close();
