Tomcat cannot unzip a War file

I am creating war files with a program using java.io.zip. When I examine the files with winzip they are correct. If I unzip the files and zip them with winzip they deploy correctly in tomcat. The code that I am using to zip is:

public void zipDir(String filePath) throws Exception
{
    File fileToZip = new File(filePath);
    if (fileToZip.isDirectory()) {
      // Get a listing of the directory content.
      String[] dirList = fileToZip.list();
      //loop through dirList, and zip the files
      for(int i = 0; i < dirList.length; i++)
      {
      File nextFile = new File(fileToZip, dirList[i]);
      if(nextFile.isDirectory())
      {
          String nextFilePath = nextFile.getPath();
          zipDir(nextFilePath);
      } else {
      zipFile(nextFile);
      }
  }
    } else {
    zipFile(fileToZip);
    }
}
 
private void zipFile(File file) throws Exception{
    FileInputStream fileInputStream = new FileInputStream(file);
    String filePath = file.getPath();
    // Remove the zip directory from the file path to create relative paths.
    int lengthOfWarDirectoryname = this.zipFolder.length();
    String zipEntryName = filePath.substring(lengthOfWarDirectoryname + 1);
    ZipEntry anEntry = new ZipEntry(zipEntryName);
    //place the zip entry in the ZipOutputStream object
    this.zipOutputStream.putNextEntry(anEntry);
    //now write the content of the file to the ZipOutputStream
    int bytesIn = 0;
    while((bytesIn = fileInputStream.read(this.byteBuffer)) != -1)
    {
    this.zipOutputStream.write(this.byteBuffer, 0, bytesIn);
    }
   //close the Stream
   fileInputStream.close();
}

I don't know what else I have to do.

Your help will be greatly appreciated.

Do you have a small example that you can email to me?
If so, I'll be happy to take a look and see if I can't spot the problem.

I will be happy to mail you the war directory and the program that i am using to zip. What is your e-mail address?
