commons FileUpload.

[sunitha reghu]

I have only used fileupload. One of the problem i faced is when the
enctype="multipart/form-data" ,all other input fields values except file can not be processed. Is there any workaround for that.

You may consult how struts handle this.

[sunitha reghu]

unfortunately im not using struts in my app.

I believe Mike meant that you should download the source code for Struts and take a look at how the Struts team has solved the problem.

Multipart form reading :
I've been using
import com.oreilly.servlet.*;
import com.oreilly.servlet.multipart.*;
import com.oreilly.servlet.multipart.MultipartParser;
You can download it. ( forgot the url).
You're also supposed to buy the book - it will be in the liscense.
It's a good book to have even if ya don't use the classes.
Peace,
jim

Jason Hunters package doesnt have that problem. But as i said using commons fileupload what is the solution.

Using Jakarta Commons FileUpload you can also process any other input field value in a multipart request. Just use the isFormField() method of the FileItem class.
Try this:

DiskFileUpload upload = new DiskFileUpload();
List pieces= upload.parseRequest(req);
Iterator iter= pieces.iterator();
while (iter.hasNext()) {
     FileItem fi= (FileItem) iter.next();
     if (fi.isFormField()) {
          //IS A FORM FIELD VALUE 
          //you can: 
          //get the name of the parameter: fi.getFieldName();
          //or get the value:  fi.getString();
     }else {
          //is a file
     }
...

ok,
even if you are not using struts as mvc model, you can still use the struts taglibs. (and the jars obviously)

[sunitha reghu]

I wont work?
I have it working on production enviroment.
Check your code or tell as what exception are you getting.

[sunitha reghu]

there is no exception. since the form type is "multipart" other input values will be null. make two text fields in spite of input type file
and check whether u able to get the values of other fields.

Just an outsider question. It seems that there are lots of open projects, each of them has its own FileUpload, or even other similar modules, like logging, etc.
In fact, why they do so? They cannot just use the same module, or share their modules to each other? I feel it is too difficult to manage so much technologies that ususally share the same functions.

Thy maven , actually Jakarta libary is the offical lib of our comany. When we need a new function, we will consult whether Jakarta has already solved it.

Hi All,
I am using the same facility of file upload.
The problem is that when I am trying to upload file using my own servlet its working fine, but when I am trying to upload using Struts(struts tags), its giving problem. Its not able to come to Action class either.
Can somebody throw light on this

Thanks in advance
Vijay
