copied!<p>I'm having a big problem in writing in my dos.write it gives me a broken pipe and I don't know how to fix it. Can anyone suggest the proper way of handling this type of error. I search to the web and says the problem is the connection but when I trying to remove the code where I write the file in outputStream the other write bytes in outputStream is working.
