Upload server + read value viarabe

[sebek]

Hello!
First, I`n new...
I want make upload file. I find some library: cos,
jakarta...fileupload, uploadbean.

I choose Jakarta. It`s a good choice?
Second. Code service should bo in: public void
doPost(HttpServletRequest
request, HttpServletResponse response) throws ServletException,
IOException? Maybe it`s stupid question butI have error:

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception

javax.servlet.ServletException: Invoker service() exception

org.apache.catalina.servlets.InvokerServlet.serveRequest(InvokerServlet.java:477)

note The full stack trace of the root cause is available in the Apache
Tomcat/5.5.15 logs.

A oto fragment kodu który jest umieszczony w metodzie doPost:
This is the code what I have in method doPost:

boolean isMultipart =
FileUpload.isMultipartContent(request);
DiskFileItemFactory factory = new
DiskFileItemFactory();
// Configure the factory here, if desired.
ServletFileUpload upload = new
ServletFileUpload(factory);
// Configure the uploader here, if desired.
List items = upload.parseRequest(request);

// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();

if (item.isFormField()) {
//processFormField(item);
} else {
//processUploadedFile(item);
}
}

It`s take from Jakarta. (example)

And one, how can I read value varaible which is sending from form?

Great Thanks!

Do you have the jakarta commons IO jar in your WEB-INF/lib/ directory
(or wherever you have commons file upload)? It looks like it is needed.
