Erro com upload

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

<%@ page import="org.apache.commons.fileupload.*, java.util.List, java.io.File, java.util.Iterator" %>

// first check if the upload request coming in is a multipart request
boolean isMultipart = FileUpload.isMultipartContent(request);

DiskFileUpload upload = new DiskFileUpload();
upload.setSizeMax(1024*1024*3);  // 3 Mb
// 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

Tenho que baixar alguma outra lib pois esta me dando esse erro:

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:
