Hi Vyacheslav,
Thanks a lot for the tip. But right now i am unable to even upload a file to
the server file system. If you have had expereince with something similar i
would appreciate if you could please give me a tip on how to retrieve the file
content from the request object.
Here is what i am trying.
BufferedReader InFile = new BufferedReader(new
InputStreamReader(req.getInputStream()));
try{
String s = "";
StringBuffer sb = new StringBuffer();
int size = req.getContentLength();
int to_read = (size > 4096) ? 4096 : size;
int bytes_read = 0;
char[] b = new char[4096];
for (int i = 0; i < size; i++) {
bytes_read = InFile.read(b, 0, to_read);
if (bytes_read == -1) {
break;
}
i += bytes_read;
to_read = ((size - i) > 4096) ? 4096 : (size - i);
s = new String(b);
sb.append(s.substring(0, bytes_read));
}
show(" sb = " + sb.toString());
The vaue of sb is printed as:
sb = f_name=abc&name=def&filename=C%3A%5Ccupofjava%5Cmails2000%5Ctest1.htm
The file i am trying to upload is: C:\cupofjava\mails2000\test1.htm
How do you retrieve the file contents from the request object after getting the
filename.
Also what is the content type that is required to be set in the HTML form while
posting the data to the servlet.
I am aware of file streams:
FileOutputStream fos;
fos = new FileOutputStream(filename);
OutputStreamWriter osw = new OutputStreamWriter( fos );
Writer OutFile = new BufferedWriter( osw );
OutFile.write( FileData );
OutFile.close();
How do you separate the file content from the request object?
Any tips/suggestions will be appreciated.
TIA.
Bye.
-Kiran.
