JSPを使用してファイルをアップロードするのに、次の2つのコードを使用しています....しかし、エラーはありませんが、ファイルはアップロードされません。 ？JSPアップロードファイルが動作していません
あなたのフォームはあなたが<input type="file" />ファイルが
enctype="multipart/form-data"おかげ Sheeyla

String contentType = request.getContentType();
//here we are checking the content type is not equal to Null and
//as well as the passed data from mulitpart/form-data is greater than or
//equal to 0
if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
{
DataInputStream in = new DataInputStream(request.getInputStream());
//we are taking the length of Content type data
int formDataLength = request.getContentLength();
byte dataBytes[] = new byte[formDataLength];
