second is upload.jsp fle

boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if (!isMultipart)
{
}
else
{
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List items = null;
try
{
items = upload.parseRequest(request);
}
catch (FileUploadException e)
{
e.printStackTrace();
}
Iterator itr = items.iterator(); //this will create iterator object from list..used for traversing the data.
String uname="",uadd="";
while (itr.hasNext())
{
FileItem item = (FileItem) itr.next();
if (item.isFormField()) //checking if its normal field then we read as normal. no need to store in disc
{
String name = item.getFieldName();
String value = item.getString();
if(name.equals("uname"))
{
uname=value;
}
else if(name.equals("address"))
{
uadd=value;
}
}
else //this else part for process about PDF file
{
try
{
String itemName = item.getName(); //this will return the pdf file name
String filename=request.getRealPath("") + "/uploads/";
filename=filename+itemName; //now concatenation the file name with upload path.
File savedFile=new File(filename);
item.write(savedFile); //saving file into disc,item contain which you select the file.
//here item will copy into the savedFile and store into disk
out.println("successfull");
response.sendRedirect("index.html");
}
catch(Exception ste)
{
out.println(ste);
}
}
}
out.println("the user name is"+uname);
out.println("the address is"+uadd);
}
%>
The above file which is used the
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
This will used for checking the whether your request is contain file data and other data or not.
for save pdf file into disc we need to creare FileItemFactory object and ServletFileUpload object
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
for reading the request we need to parse and it will return the List types.
items = upload.parseRequest(request);
Now items will contain the all data.
The request.getRealPath() will return the where deploy the your application and in my application i create uploads folder and i want to save pdf file in the uploads folder.
