read zip file on Internet Server
hi,
i wrote an applet ,and here is the part of the code:
{ ZipInputStream zin = new ZipInputStream(new FileInputStream(zipname));
ZipEntry entry;
while ((entry = zin.getNextEntry()) != null)
{
if (entry.getName().equals(fi
{ BufferedReader in = new BufferedReader(new InputStreamReader(zin));
do something.......
}
it runs well in my computer, but when i upload it the server and run, it says: the file access denied. what the possible problem for this?
i just read file on server, not write or update, why denied?
very urgent. 50pst

Unsigned applets are not permitted to access the local disk (for reading or writing).
You need to sign your applet to permit access to local disk.

the zip file is not in local disk,but in the server.

The you'll need to use a different technique to open it. Remember that the applet is running on the client, so accessing files directly will access files on the client disk.
If the zip file is visible on the web server then you can use URLConnection to open it. Otherwise you'll need to use some cgi, or a servlet.

The URLConnection class is used to make connections to URL's.
// Make a connection to a URL
URLConnection conn = new URLConnection(url);
// Get a stream for the connection
InputStream in = conn.getInputStream();
// Process data
ZipInputStream zin = new ZipInputStream(in);

hello objects
this code seems wrong:
URLConnection conn = new URLConnection(url);
the compiler said the URLConnection is abstract and cannot be instaniciated.
so how can i access this object?

in unix, sometimes the server runs under a certain account and the file has been copied their under another account name and the account the server uses does not have read access for that file.
