I received an zip file from customer. I have tried to extract with WinZip, but unable to extract zip file because that zip file was corrupt.
So I have tried to extract with Java Zip API and got the success. The code is listed below:
I am sure that the zip file having 5% to 10% part corrupt will be unzip with this code, but if it is having more corrupt then the code will not work.
import java.io.*;
import java.util.zip.*;
class ExtractCorruptZip {
public void extractZipFiles(String fileName) {
try {
String zipDir = "c:\\zip\\";
//String zipDir = "/home/usr/amit/zip/";
byte[] by = new byte[2048];
ZipInputStream ziStream = null;
ZipEntry zipEntry;
ziStream = new ZipInputStream(new FileInputStream(fileName));
zipEntry = ziStream.getNextEntry();
int count=1;
while (zipEntry != null) {
String entry = zipDir + zipEntry.getName();
entry = entry.replace('/', File.separatorChar).replace('\\', File.separatorChar);
int n;
FileOutputStream fOTStream;
File newFile = new File(entry);
if (zipEntry.isDirectory()) {
if (!newFile.mkdirs()) {
break;
}
zipEntry = ziStream.getNextEntry();
continue;
}
fOTStream = new FileOutputStream(entry);
while ((n = ziStream.read(by, 0, 2048)) > -1) {
fOTStream.write(by, 0, n);
}
System.out.println("Working....."+(++count));
fOTStream.close();
ziStream.closeEntry();
zipEntry = ziStream.getNextEntry();
}
ziStream.close();
System.out.println("DONE!!!!!");
} catch(IOException ioe) {
ioe.printStackTrace();
}
}
public static void main(String[] ss) {
try {
String fileName = "w1.zip";
ExtractCorruptZip extractCorruptZip = new ExtractCorruptZip();
extractCorruptZip.extractZipFiles(fileName);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}

Zend Framework setup
How to setup Zend Framework.
1) download ZendFramework-1.12.0 or latest framework from zend site.
2) extract it and paste the entire directory in anywhere in your system. in my case
i have copied it in my "C:\wamp\www" folder e.g. "C:\wamp\www\ZendFramework-1.12.0"
3) set envirenment path as "C:\wamp\www\ZendFramework-1.12.0\bin" and also
set path of your PHP installation directory of php.exe file e.g. "C:\wamp\bin\php\php5.4.3"
4) open dos prompt window and execute listed below command:
zf create project <projectName>
e.g. zf create project zfproj
5) copy "Zend" directory from "C:\wamp\www\ZendFramework-1.12.0\library\" into
your new project's library folder e.g. "C:\wamp\www\zfproj\library"
6) now start your wamp or any other php server and open this url in your browser
http://localhost:90/zfproj/public/
where "zfproj" is the newly created zend project and "public" is the initial home directory.
now you can get the page with
"Welcome to the Zend Framework!
This is your project's main page
Helpful Links:
Zend Framework Website | Zend Framework Manual"
Access Root Folder Of Zend Framework
Now if you don't want to use "public" folder as initial folder then follow listed below steps:
1) copy ".htaccess" and " "index.php" files from "C:\wamp\www\zfproj\public" folder into
root folder e.g. "C:\wamp\www\zfproj" folder.
2) open "C:\wamp\www\zfproj\index.php" file.
make comment this line:
//defined('APPLICATION_PATH') || define('APPLICATION_PATH',realpath(dirname(__FILE__).'/../application'));
copy paste this listed below code:
defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/application'));
now open this url "http://localhost:90/zfproj/" in your web browser.
now you will get the index page without "public" folder.
