Hi all friends,

I want to zip a folder not file by using java.util.zip package. My requirement is I have one swing interface(it is basically a uploading software)on button action event i want to zip a folder by opening Filedialog Box by selecting that folder from my hard disk.Is it possible? If it is not possible then Is there any other way to zip a folder programatically not manually.Actully I want to zip a no. of files in a single folder.So that when user unzip that zip file they can find those files in a single folder.



Hai paul,i have give programe just go throw that,it works.

You have to change instead of XML==>directory u have to give u r directory

public String[] listFiles()
File f=new File("XML"); // give ur directory path
String files[]=f.list();
return files;
public void createZipFile(String refdatabaseid)
String[] filenames = listFiles();
byte[] buf = new byte[1024];

String outFilename = "XML/"+refdatabaseid+".zip";
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename));
System.out.println("From Create Zip:"+filenames.length);

for (int i=0; i {
FileInputStream in = new FileInputStream("XML/"+filenames[i]);
out.putNextEntry(new ZipEntry(filenames[i]));
int len;

while ((len = in.read(buf)) > 0)
out.write(buf, 0, len);
