Solve the problem that the Post submission form (file upload) Request.getparameter the null value

When you encounter a form that has both a file upload and a Received field, the field wants to be request.getparameter, often null.

<form action= "FileUpload" method= "post" enctype= "Multipart/form-data" Name= "Form1" > 
   <input type= "text" Name= "text" >
   <input type= "file" name= "file" > 
    <input type= "button" Name= "Submit" value= "Upload" Onclick= "OK ()" > 
</form>

As above, call Request.getparameter ("text") in the public void DoPost (HttpServletRequest request, httpservletresponse response) To get a null

How to get it. There are two kinds of solutions

1, with two forms: (More trouble)
A from that uses a file submitted by post to upload from, a field that takes a get commit, and then the value of the second form as the first argument

function ok ()  { 
       var name = Form2.name.value; 
       var title= form2.title.value; 
       form1.action= "Fileupload?name=" +name+ "&title=" +title; 
       Form1.submit (); 
 }

2,commons-fileupload Judge FieldName, to distinguish whether the file is uploaded or field

Servletfileupload upload = new Servletfileupload (factory);    
try {    
     List  items = upload.parserequest (request);    
     for (Iterator i = Items.iterator (); I.hasnext ();) {    
                Fileitem Fileitem = (fileitem) i.next ();    
                String field = Fileitem.getfieldname ();  Judge FieldName,  
                if (field.equals ("kind")) {    
                          kind = fileitem.getstring ();    
                          Continue;    
                } else if (field.equals ("id")) {    
                         id = fileitem.getstring ();    
                         Continue;    
                } else if (field.equals ("topic")) {    
                         topic = fileitem.getstring ();    
                         Continue    
                

3, JSP SmartuploadSpecifically provided Smartupload.getrequest (). GetParameter ("text")
