hello we want to creat file upload module using JSP/Servlets API. We only allow TXT type files to be uploaded through this module. There are about 200 trusted clients will access this module to upload there information that will be stored in DataBase after some validations.
We have face some problems that are given bellow.
Can we track file type before sending it to server? ie. Rec.doc rename to Rec.txt, should not upload.
Can we track file contents to be uploaded are non harmfull? i.e Rec.exe or Rec.dll rename as Rec.txt and upload it. Can we use anti virus tools using java?
