Hi,
I have been trying to write a servlet which will
upload a file to the
server.For that i used oreilly's MultiPartRequest
class. Iam sending data
through http header from swing interface like that:-
Button.addActionListener(new ActionListener()
{
public void
actionPerformed(ActionEvent e)
{
int returnVal = fc.showOpenDialog(ActionDemo4.this);
if (returnVal ==
JFileChooser.APPROVE_OPTION) {
File file =
fc.getSelectedFile();
String
aa=file.getAbsolutePath();
textArea3.append(aa);
textArea2.append("Local URL:");
long
l=file.length();
try
{
byte buff[]=new byte[(int)file.length()];
InputStream fileIn=new FileInputStream(aa);
int i=fileIn.read(buff);
String conffile=new String(buff);
url = new URL
("http://127.0.0.1:7001/FileUpload?x="+str1);
urlConn = url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","multipart/form-data;boundary=---
--------------------------7d01ecf406a6");
printout = new DataOutputStream
(urlConn.getOutputStream ());
String
content="-----------------------------7d01ecf406a6\r\n"+"Content-
Disposition: form-data;"+"name=\"upload\";
filename=\""+aa+"\"\r\n"+"Content-Type:
text/plain\r\n\r\n\r\n"+conffile+"-
----------------------------7d01ecf406a6--\r\n";
printout.writeBytes(content);
printout.flush ();
printout.close ();
But i get the following exception:
----------------------------------
java.io.IOException: Corrupt form data: no leading
boundary
