sorry System.arraycopy() is not correct.
modified getBytes() method:
public static byte[] getBytes(InputStream inputStream) throws
IOException
{
int bufferLength = 1024;
byte[] buffer = new byte[bufferLength];
ArrayList<Byte> list = new ArrayList<Byte>();
int readLength, totalLength = 0;
while ((readLength = inputStream.read(buffer, 0, bufferLength)) >= 0)
{
for (int i = 0; i < readLength; i++)
list.add(buffer[i]);
}
byte[] retArray = new byte[list.size()];
for (int i = 0; i < list.size(); i ++)
retArray[i] = list.get(i);
return retArray;
}
