========================================================================

My HTML looks like:
<HTML>
<HEAD></HEAD>
<BODY>
<BR>
<CENTER>
<P>
UPLAOD A DOCUMENT FILE ON THE SERVER
</P>
<BR>
<FORM METHOD="POST" ENCTYPE="MULTIPART/FORM-DATA"
ACTION="FileUploadServlet">
<!-- <FORM NAME="UPLOADFORM" METHOD="POST" ACTION="FileUploadServlet">

<INPUT TYPE="FILE" NAME="UPLOADFILENAME">
<BR>
<INPUT TYPE="TEXT" NAME="TEST" VALUE="AAAAAAAAA">
<BR>
<BR>
<INPUT TYPE="SUBMIT" VALUE="UPLOAD">
</FORM>
</CENTER>
</BODY>
</HTML>
My code looks like:
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws
ServletException, IOException {
try {
boolean isMultipart =
FileUpload.isMultipartContent(request);
if(isMultipart == true) {
DiskFileUpload upload =
new DiskFileUpload();
List items =
upload.parseRequest(request, 1024*4, 1024*2000, "c:\\temp");
Iterator iter =
items.iterator();
while (iter.hasNext()) {
FileItem
item = (FileItem) iter.next();
if
(item.isFormField()) {
String name = item.getFieldName();
String value = item.getString();
System.out.println("Name = " + name);
System.out.println("Value = " + value);
}
else {
String fieldName = item.getFieldName();
String fileName = item.getName();
String contentType = item.getContentType();
boolean isInMemory = item.isInMemory();
long sizeInBytes = item.getSize();
File uploadedFile = new File("c:\\mehul\\ssl\\" + fileName);
item.write(uploadedFile);
}
}
}
request.getRequestDispatcher("UploadResponse").forward(request,
response);
}
catch(Exception e) {
e.printStackTrace();
}
}
The servlet.jar file is in server/lib directory. I am running on windows
xp machine.
Your help is appreciated.
