junk characters in netui:form with enctype="multipart/form-data"

[carlos rivera]

Hello all

I have a JSP that goes like this:

<%@ page language="java" contentType="text/html;charset=UTF-8"%>
...
<netui:form action="modifyData" tagId="myForm"  enctype="multipart/form-data"  onSubmit="return validate()" >
<netui:textBox dataSource="{actionForm.name}" />
<netui:fileUpload dataSource="{actionForm.file}"  />
</netui:form>
...
   

In others JSPs within the same app (each document share the same codification tag) I can add data with special characters like ñ, á , ö, ê , etc.
however, in this particular form, they're added to database as junk characters like á , ñ , ...
I've already changed my tables' codification to UTF-8, to no avail

I believe it has something to do with the enctype="multipart/form-data" parameter

Is there anything you can suggest to stop this from happening?
I'm using BEA Weblogic 8.1.3

Thank you in advance

Are the special characters coming from the file ? The encoding problem might not be with the database but with the file itself. Perhaps it was saved with the wrong encoding ?

no, the problem is the text being inserted in the database, i use the netui:fileupload for uploading an image to the server, and that works just fine.

You read images with streams and encoding should not be a problem there. Text is a different matter. Does the problem occur when the file is uploaded or when the uploaded contents are inserted into the DB ?

[carlos rivera]

the problem occurs whether I upload a file or not, everytime I enter 'foreign' characters. When I print the text in console, BEFORE doing the insert to the DB, it's already corrupted. Weblogic is somehow changing the codification of text in this particular Form.

It is probably not weblogic's fault. Set the encoding of the JSP page to display. If you are reading this input in some form (instead of having net UI read it automatically), then mention the encoding of the text.

This page http://java.sun.com/j2ee/1.4/docs/tutorial/doc/WebI18N5.html offers some good advice on encoding in its various forms.

Deepak:

Is only when the enctype="multipart/form-data" parameter is removed form the <netui:form> tag, that everything works as expected (I can insert and retrieve accented characters).

I tried the suggestions you gave me, but the characters still change arbitrarily, and every JSP for data input and display are declared to be UTF-8 compliant.

Have you tried using commons file upload ? http://commons.apache.org/fileupload/

You should have no problem reading the characters if it is UTF-8 compliant and you use the commons upload API for multipart uploads.
