Unzip module

[Noél Dubau]

Hello

In the SM sample file exists an Unzip module requiring to choose the zip file ; the file is expanded in a folder named as the original file

Has someone adapted this module in the idea of unzipFile(filesource ; folderDestination)

Thanks for links

hello dear Noël 😊
yes, easy with two parameters sourcePath and destPath :

Quote

import java.util.zip.*;
import java.io.*;
import java.util.*;

if(sourcePath == null || sourcePath.equals("") || destPath == null || destPath.equals("")) {
    return 'Les paramètres sourcePath et destPath doivent être renseignés'
}

/*
* Create directory with the name of the zip file
*
* For e.g. if we are going to extract c:/demo.zip create c:/demo
* directory where we can extract all the zip entries
*
*/
try {
    File fSourceZip = new File(sourcePath);
    String zipPath = destPath

    File temp = new File(zipPath);
    temp.mkdir();
    /*
    * Extract entries while creating required
    * sub-directories
    *
    */
    ZipFile zipFile = new ZipFile(fSourceZip);
    Enumeration e = zipFile.entries();

    while(e.hasMoreElements()) {
        ZipEntry entry = (ZipEntry)e.nextElement();
        File destinationFilePath = new File(zipPath,entry.getName());

        //create directories if required.
        destinationFilePath.getParentFile().mkdirs();

        //if the entry is directory, leave it. Otherwise extract it.
        if(entry.isDirectory()) {
            continue;
        }
        else {
            System.out.println("Extracting " + destinationFilePath);
        
            /*
            * Get the InputStream for current entry
            * of the zip file using
            *
            * InputStream getInputStream(Entry entry) method.
            */
            BufferedInputStream bis = new BufferedInputStream(zipFile.getInputStream(entry));

            int b;
            byte[] buffer = new byte[1024];

            /*
            * read the current entry from the zip file, extract it
            * and write the extracted file.
            */
            FileOutputStream fos = new FileOutputStream(destinationFilePath);
            BufferedOutputStream bos = new BufferedOutputStream(fos,1024);

            while ((b = bis.read(buffer, 0, 1024)) != -1) {
                bos.write(buffer, 0, b);
            }

            //flush the output stream and close it.
            bos.flush();
            bos.close();

            //close the input stream.
            bis.close();
        }
    }
    zipFile.close();
}
catch(IOException ioe) {
            return "IOError :" + ioe;
}

return 1;
