Hi friend,

Code to help in solving the problem :

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

public class ZipCreateFile{
public static void main(String[] args) throws IOException{
System.out.print("Please enter file name to zip : ");

BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
//String filesToZip = input.readLine();
String filesToZip = "C:\\apache-tomcat-6.0.13\\webapps\\ROOT\\showname.jsp";
File f = new File(filesToZip);
if(!f.exists()){
System.out.println("File not found.");
System.exit(0);
}
System.out.print("Please enter zip file name : ");
String zipFileName = input.readLine();
if (!zipFileName.endsWith(".zip"))
zipFileName = zipFileName + ".zip";
byte[] buffer = new byte[18024];
try{
ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFileName));
out.setLevel(Deflater.DEFAULT_COMPRESSION);
FileInputStream in = new FileInputStream(filesToZip);
out.putNextEntry(new ZipEntry(filesToZip));
int len;
while ((len = in.read(buffer)) > 0){
out.write(buffer, 0, len);
}
out.closeEntry();
in.close();
out.close();
}
catch (IllegalArgumentException iae){
iae.printStackTrace();
System.exit(0);
}
catch (FileNotFoundException fnfe){
fnfe.printStackTrace();
System.exit(0);
}
catch (IOException ioe){
ioe.printStackTrace();
System.exit(0);
}
}
}

Thanks
