Attachment and closed stream opening a zip file

[Philippe Frangioni <pf...@wimba.com>]

Hi all,

I'm trying to send a zip file using attachments. In fact it works. My 
only problem is that I can't open the zip file I saved on the server.

This is my code:

////////////////////////////////////////////////////////////////////////////////////////////////

        InputStream is = null;
        FileOutputStream os = null;
       
        try
        {
            // File names vector
            Vector fileInfo = (Vector) obj;
           
            // Get all the attachments
            AttachmentPart[] attachments = getMessageAttachments();
           
            // Put the logic in a loop for totalAttachments for multiple 
attachments.
            int totalAttachments = attachments.length;
            System.out.println("Total Attachments Received Are: " + 
totalAttachments);
           
            // Extract the first attachment. (Since in this case we have 
only one attachment sent)
            DataHandler dh = attachments[0].getDataHandler();
           
            // Extract the file name of the first attachment.
            String name = (String) fileInfo.get(0);
            System.out.println("File received on server is: " + name);
           
            // An input stream on the uploaded file
            is = dh.getInputStream();
           
            .....
            String contentDirectory = "...............";
            .....
           
            File file = new File(contentDirectory, name);
            os = new FileOutputStream(file);
            int i = 0;
            while (i != -1)
            {
                i = is.read();
                os.write(i);
            }
            is.close();
            os.close();
           
            //dh = null;
    
            System.out.println("file.getName() = " + 
file.getName());           // -> return the good name
            System.out.println("file.getPath() = " + 
file.getPath());               // -> return the good path
            System.out.println("file.isFile() = " + 
file.isFile());                       // -> return true
            System.out.println("file.length() = " + 
file.length());                   // -> return the good length
            System.out.println("file.canRead() = " + 
file.canRead());            // -> return true
            System.out.println("file.canWrite() = " + 
file.canWrite());           // -> return true
           
            FileInputStream fis = new FileInputStream(contentDirectory + 
"/" + name);
            CheckedInputStream checksum = new CheckedInputStream(fis, 
new Adler32());
            ZipInputStream zis = new ZipInputStream(new 
BufferedInputStream(checksum));
            ZipEntry zEntry;
           
            while ((zEntry = zis.getNextEntry()) != null)
            {
                if (!zEntry.isDirectory())
                {
                    //InputStream isz = zFile.getInputStream(zEntry);
                   
                    OutputStream osz = new BufferedOutputStream(new 
FileOutputStream(contentDirectory.getAbsolutePath() + "/" + 
zEntry.getName()));
                    byte[] buffer = new byte[2048];
                    int len = 0;
                    int count;
                    //while ((len = isz.read(buffer)) >= 0)
                    while ((count = zis.read(buffer, 0, buffer.length)) 
!= -1)
                    {
                        osz.write(buffer, 0, count);
                    }
                    osz.close();
                    zis.close();
                }
                else
                {
                    new File(contentDirectory.getAbsolutePath() + "/" + 
zEntry.getName()).mkdir();
                }
            }
           
        }
        catch (Exception e)
        {
            status = "File Could Not Be Saved: " + e.getMessage();
            System.out.println("In Impl: " + e);
            System.out.println("Message: " + e.getMessage());
            e.printStackTrace();
        }
       
        return status;

I get an exception on line :

while ((zEntry = zis.getNextEntry()) != null)

The exception is:

I read here:
http://marc.info/?l=axis-user&m=109603822200704&w=2

that there is a solution, but I wanted to know if there is a "cleaner" 
one.... I'm using Axis 1.4.

Thank you,
Phil
