pessoal estou tentando fazer um upload usando a commons.fileupload da jakarta peguei um código aqui do guj mesmo mas esta me retornando um erro:
upload.jsp

// first check if the upload request coming in is a multipart request

DiskFileUpload upload = new DiskFileUpload();

// parse this request by the handler
// this gives us a list of items from the request
List items = upload.parseRequest(request);
Iterator itr = items.iterator();
while(itr.hasNext()) {
FileItem item = (FileItem) itr.next();
// check if the current item not is a form field or an uploaded file
if(!item.isFormField()) {
// the item must be an uploaded file save it to disk. Note that there
// seems to be a bug in item.getName() as it returns the full path on
// the client's machine for the uploaded file name, instead of the file
// name only. To overcome that, I have used a workaround using
// fullFile.getName().
File fullFile = new File(item.getName());
String nome = fullFile.getName();//pega o nome do arquivo
String extensao=nome.substring(nome.length()-3,nome.length());//pega a estenção do arquivo
out.println(nome+"<br>");
out.println(extensao+"<br>");
if (extensao.equalsIgnoreCase("JPG")) {//só envia se for JPG
File savedFile = new File(getServletContext().getRealPath("/ola/"),fullFile.getName());
item.write(savedFile);
}
else {
out.println("Não enviando. Use apenas JPG");
}
}
}
%>
</body>
</html>
mas esta me dando o seguinte erro:

se alguem puder me ajudar!
Ao invés de usar DiskFileUpload utilize ServletFileUpload
// Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();
// Set factory constraints
factory.setSizeThreshold(1);
// Create Temp Repository
File fileTemp = new File("C:\\Temp");
factory.setRepository(fileTemp);
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Set overall request size constraint in bytes
upload.setSizeMax(4000000);
// Parse the request
Tenho que baixar alguma outra lib pois esta me dando esse erro:

A biblioteca commons-fileupload esta no seu WEB-INF/lib?
sim e as classes estao todas la…
estou importando assim: org.apache.commons.fileupload.*
Estou levantando esse post para não abrir outro com o mesmo assunto e porque ainda não foi respondido.
Estou com o mesmo problema do amigo acima.
O erro é manifestado pela linha “List items = upload.parseRequest(request);”
O erro no apache:
