File with COS Upload to implement file upload in JSP, available type libraries, such as famous JSPSMART SMARTupload, Struts is also available. I said COS, it is O'Reilly, O'Reilly book is very 8 wrong, this uploaded component is great, the most important thing is that it is Open Source.
Download the latest COS package (http://www.servlets.com/cos/index.html), join your ClassPath. Write a JSP that needs to upload files. For convenience, I use a simple HTM file. In this page, we let users upload 3 files at a time. /upload.htm
No title document </ title> </ head> <body> <! - ENCTYPE value is important, UPLOAD.JSP is the process uploaded JSP -> <form name = "form1" method = "post" enctype = "multipart / form-data" action = "upload.jsp"> <p> <input name = "file1" TYPE = "file"> </ p> <p> <input name = "file2" type = "file"> </ p> <p> <input name = "file3" type = "file"> </ p> <p> <input type = "submit" name = "submit" value = "Upload"> </ p> </ form> </ body> </ html> in C: / Request a directory C: / Upload, Used to store the uploaded file. Write a JSP or servlet to upload, I use a UPLOAD.JSP here, so you don't have to configure web.xml, huh, it is more lazy.</p></div><div class="text-center mt-3 text-grey">
