Problem in creating zip file.

Question

Hi,
I am using the zip package to create a zip file.The code is given below :
  ZipOutputStream out = new ZipOutputStream(new
  BufferedOutputStream(new FileOutputStream("d:\\abc\\target.zip")));
    byte[] data = new byte[1000];              
    BufferedInputStream in = new BufferedInputStream
(new FileInputStream("d:\\abc\\xyz.log"));
    int count;
   out.putNextEntry(new ZipEntry("d:\\abc\\target.zip"));
   while((count = in.read(data,0,1000)) != -1)
   out.write(data, 0, count);
   in.close();
   out.flush();
   out.close();The problem is that the zip file created is having no files when i try to zip files from locations other than the program file location ie other than current drive.
Could you please suggest me a solution so that it zips file from any location. Thanks in advance.

Could you please suggest me a solution so that it zips file from any location. Thanks in advance.My advice would be to tryout something as given below and checkout whether that can
a). Give you Exception Message/stack trace if an error has occured
b). Check whether the appropriate code change works
public compressFile(String inputFile,String destFile){
ZipOutputStream out = null;
byte[] data = null;
BufferedInputStream in = null;
try{
    out = new ZipOutputStream(new BufferedOutputStream(new FileOutputStream(destFile)));
    data = new byte[1024];
     try{               
         in = new BufferedInputStream(new FileInputStream(inputFile));
         int count = -1;
         out.putNextEntry(new ZipEntry(inputFile));
         while((count = in.read(data)) > 0){     
            out.write(data, 0, count);
       }catch(Exception e){
           System.err.println(e.getMessage());
           e.printStackTrace();
       }finally{       
              if(in != null)
                 try{in.close();}catch(Exception ex){}
   out.flush();
}catch(Exception exp){
    System.err.println(exp.getMessage());
    exp.printStackTrace();
}finally{
  if(out != null)
     try{out.close();}catch(Exception e){}
   out = null;
   in = null;
}in order to compress the file we can call the method something like
compressUtilObj.compressFile("d:\\abc\\target.zip","d:\\abc\\xyz.log");Hope that helps :)
