don't know what the reason is? How should it be solved?
To resolve this error, you need to add the enctype= "Multipart/form-data" attribute to the form form, but you cannot use Request.getparameter () when the form request is passed to another JSP or servlet. To get the values of the individual form elements, as follows:
Copy Code code as follows:
<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "
pageencoding= "UTF-8"%>
<%@ page session= "false"%>
<%@ include file= "/common/taglibs.jsp"%>
<%@ include file= "/common/meta.jsp"%>
<%@ include file= "/common/js.jsp"%>
<%@ page import= "java.util.*"%>
<%@ page import= "Java.text.SimpleDateFormat"%>
<%@ page import= "Sdcncsi.ict.util.SysPara"%>
<% @page import= "java.io.*,java.util.*,sdcncsi.ict.base.attachment.*"%>
<%@ page import= "Sdcncsi.ict.util.RequestUtil"%>
<% @page import= "Com.oreilly.servlet.MultipartRequest"%>
<%
String res= "true";
Request.setcharacterencoding ("UTF-8");
Response.setcontenttype ("text/html; Charset=utf-8 ");
String file= (String) request.getparameter ("T_file_excel");
System.out.println (file);
String accountid3= (String) request.getparameter ("Accountid3");
String savedirectory = "";
Get configuration parameters, file type, file size
/*string date = "";
SimpleDateFormat GS = new SimpleDateFormat ("YyyyMMdd");
Date now = new Date ();
Date = Gs.format (now);
Filefuns filefuns = new Filefuns ();
try {
Determining File Types
String file_type=syspara.getvalue ("Dxt_sms_multi_sender_file_type");
if (!file.substring (File.lastindexof (".") +1). Equals (File_type))
{
Out.println ("<script>");
Out.println (' Alert (' ERROR: File type Error! ');");
Out.println ("</script>");
Return
}
To determine if a folder exists, there is no creation
String File_path = Syspara.getvalue ("Dxt_sms_multi_sender_file_path");
File_path=file_path.replace ("\", "//");
if (!filefuns.getfileisexists (File_path)) {
Filefuns.createdir (File_path);
}
String file_size = Syspara.getvalue ("Dxt_sms_multi_sender_file_size");
File upload, save in Savedirectory
Savedirectory = File_path;
Randomfilerenamepolicy RFRP = new Randomfilerenamepolicy ();
Multipartrequest multi = null;
System.out.println ("Savedirectory" +savedirectory);
System.out.println ("File_size" +file_size);
