how to put two different folders(which is in different location) into one zip entry

[Seetharaman Venkatasamy]

Hi Folks,

I have log files in different location in my system say C:\\javaLog and D:\\cLog i need to compress these folders and put into a single zip file .

How can i do this?. i tried with java.util.zip...but i cant make it exactly what i want.Please give me an idea .

Don't think this is a beginner's topic. Moving.

The issue will be the names for the ZIP entries, and recursion comes to the rescue:

public void addToZip(ZipOutputStream zipStream, File file)
{
    addToZip(zipStream, file, file.getName());
}

private void addToZip(ZipOutputStream zipStream, File file, String name)
{
    if (file.isDirectory())
    {
        File[] files = file.listFiles();
        // check for null in case you don't have read rights
        if (files != null)
        {
            for (File f: files)
            {
                String fileName = name + "/" + f.getName();
                addToZip(zipStream, f, fileName);
            }
        }
    }
}

This method will take the original name (e.g. javaLog), and all of its files will keep that name part (e.g. javaLog/image.jpg, javaLog/folder/document.txt, etc).

I omitted the actual zipping part, but I don't think that will be a problem.

the two log folders are in different location.

   

package com;

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

public class ZipFolder {

	static public void zipDir(String dir2zip, ZipOutputStream zos) {
		try {

			//create a new File object based on the directory we have to zip File 
			File zipDir = new File(dir2zip);
			//get a listing of the directory content 
			String[] dirList = zipDir.list();
			byte[] readBuffer = new byte[2156];
			int bytesIn = 0;
			//loop through dirList, and zip the files 
			for (int i = 0; i < dirList.length; i++) {
				File f = new File(zipDir, dirList[i]);
				System.out.println("DIRECTORY LIST=====>"+dirList[i]);
				if (f.isDirectory()) {
					//if the File object is a directory, call this 
					//function again to add its content recursively 
					String filePath = f.getPath();
					System.out.println("FILE PATH=====>"+filePath);
					zipDir(filePath, zos);
					//loop again 
					continue;
				}
				//if we reached here, the File object f was not  a directory 	           
				//create a FileInputStream on top of f 
				FileInputStream fis = new FileInputStream(f);				
				//create a new zip entry 
				ZipEntry anEntry = new ZipEntry(f.getPath());
				//place the zip entry in the ZipOutputStream object 
				zos.putNextEntry(anEntry);								
				//now write the content of the file to the ZipOutputStream 
				while ((bytesIn = fis.read(readBuffer)) != -1) {
					zos.write(readBuffer, 0, bytesIn);
				}
				
				
				//close the Stream 
				fis.close();

			}
		} catch (Exception e) {
			//handle exception 
			e.printStackTrace();
		}
	}

	//zipLogs()
	public static void main(String ...args) {
		try {
			
			String logPath = "E:\\inFolder\\rb,E:\\inFolder\\java";
			String zipName = "Seethu";String azipName = "Seethu_a";
			String outPath = "E:\\out_zip";
			
			String clientLogFolder = logPath;//timing there  is only one path as harish instructed
			String zipClientLogFolder = outPath+"\\"+zipName+".zip";
			
			String[] splitZipClientLogFolder = zipClientLogFolder.split("\\\\");

			File makeOutFolder = new File(splitZipClientLogFolder[0]
					+ splitZipClientLogFolder[1]);
			makeOutFolder.mkdir();

			ZipOutputStream zos = null;
			String[] mutiplePath = clientLogFolder.split(",");
			for (String pathName : mutiplePath) {				
				//create a ZipOutputStream to zip the data to write
				zos = new ZipOutputStream(new FileOutputStream(zipClientLogFolder));
				zipDir(pathName, zos);//Here path Name is inputFolder[directory need to zip]

				//close the stream . and must be end of this for loop
				zos.close();				
			}
			
			System.out.println("ZIP CREATED SUCCESSSFULLY");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}



 

Here i am getting the zip file .if i extract i am getting inFolder\\java . thats is second path is overridding the first one. i want both folder in one zip .


Note: under the inFolder there are many logfolder. i need only two of them(in some situation). so i reject to zip the parent folder(inFolder)

Thanks Rob. problem solved.

i need to put

  zos = new ZipOutputStream(new FileOutputStream(zipClientLogFolder));    

outside the for loop
