java.io.FileNotFoundException occuring while unzipping in android

Question

I am trying to unzip a zip file. This file contains several other files.The method I am using is:

private void unzipFile(String inputFileName,String outputDirName){
    int dataCount=0;
    byte[] dataArr=null;
    File inputZipFile=null,targetDir=null,unzipFile=null;
    ZipInputStream zipIPStream=null;
    ZipEntry zipEntry=null;
    BufferedOutputStream bfrOPStream=null;
    FileOutputStream unzipOPStream=null;
    try{
        inputZipFile=new File(inputFileName);
        targetDir=new File(outputDirName);
        zipIPStream=new ZipInputStream(new BufferedInputStream(new FileInputStream(inputZipFile)));
        while((zipEntry=zipIPStream.getNextEntry())!=null){
            dataArr=new byte[2048];
            // zipEntry=zipIPStream.getNextEntry();
            System.out.println("ZipEntry:"+zipEntry.getName());
            unzipFile=new File(targetDir.getAbsolutePath()+"/"+zipEntry.getName());
            System.out.println("Checking the path:"+unzipFile.getPath());
            if(!unzipFile.getParentFile().exists()){
                unzipFile.getParentFile().mkdirs();
            }
            unzipOPStream=new FileOutputStream(targetDir.getPath()+"/"+zipEntry.getName());
            bfrOPStream=new BufferedOutputStream(unzipOPStream,2048);
            while((dataCount=zipIPStream.read(dataArr,0,2048))!=-1){
             unzipOPStream.write(dataArr,0,dataCount);
            }
            unzipOPStream.flush();
            unzipOPStream.close();
        }
    }catch(IOException ioe){
        ioe.printStackTrace();
    }catch(Exception e){
        e.printStackTrace();
    }finally{
        if(zipIPStream!=null){
            try{
                zipIPStream.close();
            }catch(Exception e){

            }
        }
    }
}

The method is throwing the following error

10-22 13:33:09.896: W/System.err(446): java.io.FileNotFoundException: /mnt/sdcard/iR/testbook/Caterpillar-Insect-Animal-Macro-HD-600x375.jpg (Not a directory)

in which line the error occurs? it seems that it's trying to read this .jpg as a directory which is not correct.. — ColdFire, Oct 22 '12 at 11:40
I got the solution. I was trying to unzip the file in the same directory in which it was kept. I changed the directory and now method is working fine. — Richa Laad, Oct 22 '12 at 12:19
