FTP file via proxy

[rengaraj]

Hello,

I try to upload a file via ftp while using a proxy-server.
My code is giving me the following error even when using: urlc.setDoOutpu t(true);

java.net.Protoc olException: cannot write to a URLConnection if doOutput=false - call setDoOutput(tru e)

public class FTP{

public static void main (String args[]){

System.getPrope rties().put("ft pProxySet","tru e");
System.getPrope rties().put("ft pProxyHost","ft pproxy.xxx.xx") ;
System.getPrope rties().put("ft pProxyPort","21 ");


File source = new File("c:\\debug log.log");
BufferedInputSt ream bis = null;
BufferedOutputS tream bos = null;
try {
URL url = new URL("ftp://user:pwd@users. telenet.be;type =i");
URLConnection urlc = url.openConnect ion();

urlc.setDoOutpu t(true);
// urlc.setDoInput ( true );
bos = new BufferedOutputS tream(urlc.getO utputStream());
bis = new BufferedInputSt ream(new FileInputStream (source.getName ()));
int i;
while ((i = bis.read()) != -1) {
bos.write(i);
}
} catch (MalformedURLEx ception e) {
// TODO Auto-generated catch block
e.printStackTra ce();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTra ce();
} finally {
if (bis != null) {
try {
bis.close();
} catch (IOException ioe) { /* ignore */
}
}
if (bos != null) {
try {
bos.close();
} catch (IOException ioe) { /* ignore */
}
}
}

}
}
