我需要在我的服務器上存儲cad
文件,但我無法使上傳正常工作。我試圖讓這個工作幾個小時,但我不能。 Atm我有這個。 這給了我,上傳servlet中的文件
隨機數 .temp不存在(java.io.FileNotFoundException: /home/nick/.netbeans/7.1.2/config/GF3_1/domain1/generated/jsp/lrt/upload_700679fb_13a96c78523__7ffb_00000006.tmp (No such file or directory)

Collection<Part> parts = request.getParts();
if (parts.size() != 3) {
//can write error page saying all details are not entered
}
Part filePart = request.getPart("cad");
InputStream sInputStream = filePart.getInputStream();
//read imageInputStream
filePart.write(filePart.getName());
//Read Name, String Type
Part namePart = request.getPart("cad");
if(namePart.getSize() > 20){
//write name cannot exceed 20 chars
}
//use nameInputStream if required
InputStream nameInputStream = namePart.getInputStream();
//name , String type can also obtained using Request parameter
String nameParameter = request.getParameter("name");
//Similarly can read age properties
Part agePart = request.getPart("age");
int ageParameter = Integer.parseInt(request.getParameter("age"));
}
@Override
public String getServletInfo() {
return "Short description";
}
}
那麼您的註釋現在是怎樣的?該錯誤可能與'location'屬性有關。 – home
@home我用完整的servlet編輯了我的代碼。 – Nick
