mutipart/form-data

[Balaji Loganathan]

I have html form element with ENCTYPE="MULTIPART/FORM-DATA"
that is

<form method="post" action="/servlet/controllerServlet" enctype="MULTIPART/FORM-DATA">
   <input type="hidden" name="action" value="fileupload" />
   <input name="id" />   
   <input type="file" name="file1" size="50">   
   <input type="submit" value="Upload">
</form>

I couldn't able to read the values of the parameter action,id using request.getParameter(..) method,
please tell me how to capture that values ?
Regards
Balaji

Hi Balaji,
In case of MULTIPART/FORM-DATA the request parameters can only be read after saving the file, using JspSmartUpload or other 3rd Party softwares.

But if you need to read values before saving the file then there is one tricky method. Set all the parmeters as query string which you need to access using request.getParameter("parma#").
Note for this you must change your form action as
"servlet/controllerServlet?param1=value1&param2=value2&param3=value3"

<form method="post" 
         action="/servlet/controllerServlet?param1=value1&param2=value2&param3=value3"
         enctype="MULTIPART/FORM-DATA">
  <input type="hidden" name="action" value="fileupload" /> 
  <input name="id" />
  <input type="file" name="file1" size="50">
  <input type="submit" value="Upload">
</form>

Hope this will answer your query.

Unfortunately!. Its not possible for my case where i have to get the input typed by the user.
In my case the user will select a particular language,then type his/her id,then select the file to upload.
Please help with this scenario ?

Hi Balaji
Then you will have to use JspSmartUpload or other 3rd Party softwares.
You can download JspSmartUpload from JspSmart
The code is something like this

  JspSmartUpload myUpload = new JspSmartUpload();
  myUpload.upload();
  myUpload.getRequest().getParameter("param#");
