its supposed to zip folder content recursively, which it does until it encounters a folder with both an empty folder and a non-empty. or so i think.
i used the following structure to zip: http://img291.imageshack.us/img291/6120/84976017.jpg if untitled folder is removed it works. any tips would be much appreciated.
import java.io.*;
import java.util.zip.*;
public class Compress {
static File rootDir;
static FileInputStream fis;
static ZipOutputStream zos;
static String fsep; //file separator
static void zipContents(File[] file, String dir) {
//dir - directory in the zip file
byte[] buffer = new byte[4096];
try {
for(int i=0; i<file.length; i++) { //zip files
if(file[i].isFile()) {
fis = new FileInputStream(file[i]);
zos.putNextEntry(new ZipEntry(dir+file[i].getName()));
//shows how its stored
//System.out.println(dir+file[i].getName());
int bytes_read;
while((bytes_read = fis.read(buffer))!=-1) zos.write(buffer, 0, bytes_read);
fis.close();
}
} //for
//create empty dir if theres no files inside
if(file.length==1) zos.putNextEntry(new ZipEntry(dir+fsep)); // this part is erroneous i think
for(int i=0; i<file.length; i++) { //zip directories
if(file[i].isDirectory()) {
File subList[] = file[i].listFiles();
//for dir of varying depth
File unparsedDir=file[i];
String parsedDir=fsep+file[i].getName()+ fsep; //last folder
while(!unparsedDir.getParentFile().getName().equals(rootDir.getName())) {
unparsedDir = file[i].getParentFile();
parsedDir =fsep+unparsedDir.getName() + parsedDir;
}
parsedDir=rootDir.getName()+parsedDir; //add input_output as root
zipContents(subList, parsedDir);
}
} //for
} catch(IOException ioex) { ioex.printStackTrace(); }
}
public static void main(String args[]) throws IOException, FileNotFoundException {
fsep = File.separator;
rootDir = new File(System.getProperty("user.dir")+fsep+"src"+fsep+"input_output");
File list[] = rootDir.listFiles();
zos = new ZipOutputStream(new FileOutputStream(rootDir+".zip"));
zipContents(list, rootDir.getName()+fsep);
zos.close();
}
}
