Message:

send zip file across wire using client / server sockets

Posted by John on August 30, 2000 at 4:11 PM

Hi,
I'm writing a simple server program which takes a zip file and tries to write its contents to the output stream of a socket.

Platform: windows NT 4.0
jdk 1.2.2-006

PROBLEM: a java.net.SocketException is thrown when I call putNextEntry of ZipOutputStream.

Here's the stack trace:
ava.net.SocketException: Connection reset by peer: socket write error
at java.net.SocketOutputStream.socketWrite(Native Method)
at java.net.SocketOutputStream.write(Unknown Source)
at java.util.zip.ZipOutputStream.writeInt(Unknown Source)
at java.util.zip.ZipOutputStream.writeLOC(Unknown Source)
at java.util.zip.ZipOutputStream.putNextEntry(Unknown Source)
at classloader.SampleServer.invokeServer(SampleServer.java:81)
at classloader.SampleServer.main(SampleServer.java:54)

Here's the code snipet from my SampleServer class:

serverSocket = new ServerSocket(4444);
clientSocket = serverSocket.accept();
zipOutputStream = new ZipOutputStream (clientSocket.getOutputStream());
//archive is my existing zip file
archive = getZipFile();
for (Enumeration e = archive.entries(); e.hasMoreElements();)
{
ZipEntry zipEntry = (ZipEntry) e.nextElement();
//****here's where the problem seems to lie***********
zipOutputStream.putNextEntry(zipEntry);
}

Please let me know what I'm doing wrong, and how I can fix it so I can send zip file contents across, using sockets.

Thanks,
John
