HI,

How to read from the stream and write it to a file instead writing byte by byte. Here is code

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
FileOutputStream fos = new FileOutputStream(bkpFile); 
 
InputStream inStrm = post.getResponseBodyAsStream(); 
 
int bytesRead = inStrm.read(byteData); 
 
int totalBytes = 0; 
 
while(bytesRead > 0) 
 
{ 
 
totalBytes++ ; 
 
fos.write(byteData) ; 
 
bytesRead = inStrm.read(byteData); 
 
} 
 
fos.close(); 
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

Here, post.available() returns 0,

Please help.
Regards,

Hi,

you have to declare byteData as an array. For example:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

byte[] byteData = new byte[4096]; // <------
 
FileOutputStream fos = new FileOutputStream(bkpFile);
 
InputStream inStrm = post.getResponseBodyAsStream();
 
int bytesRead = inStrm.read(byteData);
 
int totalBytes = 0;
 
while(bytesRead > 0)
 
{
 
<span style="font-weight: bold">totalBytes += bytesRead;</span>
 
fos.write(byteData) ;
 
bytesRead = inStrm.read(byteData);
 
}
 
fos.close(); 
Parsed in 0.032 seconds,  using GeSHi 1.0.8.4

Moreover, it's good to use BufferedOutputStream/BufferedInputStream to minimize disk usage.
