File upload example

[Prakash Rai]

List items = uploadHandler.parseRequest(request);
			Iterator itr = items.iterator();
			while (itr.hasNext()) {
				FileItem item = (FileItem) itr.next();
				if (item.isFormField()) {
					out.println("<br/><h1>File Name=" + item.getFieldName()
							+ ",value =" + item.getString());
				} else {
					out.println("<br/><h1>Field Name=" + item.getFieldName()
							+ ",File name=" + item.getName()
							+ ", Content type=" + item.getContentType()
							+ ",File Size=" + item.getSize());
					File file = new File(destinationDir, item.getName());
					item.write(file);
				}

In above code why I am getting error at line 02,03,04.?

It might help if you actually told us what the error was.

And also what the context is. I assume that you're asking about a web application of some kind, but you posted this in JDBC (where it clearly doesn't belong) so maybe it isn't. I'm going to take a guess and move it out of JDBC anyway.

this Program to upload the file. Related to Servlet program.

"Type mismatch: cannot convert from Iterator to ObjToIntMap.Iterator" this is Error

[Ulf Dittmer]

That's due to the import statement in line 14; what's that supposed to accomplish? What kind of object is actually needed in line 40?
