i need program that upload large binary files using FTP in Java
hi everyone,
i face problem while uploading a big binary files(say 50MB) using TCP/IP sockets in java which intenally uses the BufferStreamReader and bufferstream writer to read from local machine and write bytes on remote machine, it successfully upload files upto 20 MB but beyond that i get crashed.
Pls. assist how to get rid from this situation
Note:
i use thread which count upto 1000 times it read and write bytes in small chunks say byte of [4096] , when counter reaches 1000 it get some suspend state so that user checks how much data has been uploaded,
If someone needs more clarification on my problem feel free to reply on kulsingh@quark.com
Its very thory issue and i need to resolve it asap
> Did you say that you are using 1000 threads to write?
No, he didn't. He said he's using a thread that reports progress after every 1000 read/write ops.
> which internally uses the BufferStreamReader and bufferstream writer
There is no such class, and you can't use Readers and Writers on binary data, as sabre150 said.
> it successfully upload files upto 20 MB but beyond that i get crashed.
You 'get crashed' how? This tells us nothing.
> Pls. assist how to get rid from this situation
What situation? You do realize that you haven't actually told us yet? Maybe the server you're uploading to has a 20MB upload limit.

Much too small. Make them at least 16k, preferably 64k.
> when counter reaches 1000 it get some

Why? Why not just use a javax.swing.ProgressMonitor? Why aren't you using an FTP URL?
Make your life easier.
