Problem: FormPanel / FileUpload - special characters and german umlauts

[GWT-Newbie]

Hey there,

using the FormPanel with the FileUpload widget, the strings from the
TextBoxes and TextAreas of my FormPanel don't support some special
characters and german umlauts.
On the client-side everything is okay, but arriving at the server, the
characters and umlauts (like ä ü ö) were replaced e.g. with s.th. like
"ü � ä ö ü" and so on.
My server-side will send eMails with those Strings and I would like to
have them correctly.
Can anyone of you guys help me? Would be great!

Cheers!

This looks like UTF-8 being interpreted as if it were Latin-1 (or
similar // ISO-8859-1 or similar). Check your server-side code.

[GWT-Newbie]

On the client side, I did "uploadForm.setEncoding
(FormPanel.ENCODING_MULTIPART);"
In the server code, I have nothing like a encoding or a charset
setting.

I have no idea to fix it, dan anyone help me?

[GWT-Newbie]

I tried request.setCharacterEncoding(text/hmtl; UTF-8" and got the
same result. -.-

check that your html file has the correct content type:
<meta http-equiv="content-type" content="text/html; charset=UTF-8">

then put a breakpoint in your servlet and check if the special chars
are still ok

and make sure, to use the correct method on your form
setMethod(FormPanel.METHOD_POST)

[GWT-Newbie]

Thanks for your answer!

My html file has the correct type and I am using the correct method on
your form.
In the Client, the special chars of the FormPanel items are still ok,
before it's submitted. (e.g. "Grüße")
If I get the Strings of the submitted items in the servlet
(item.getString()), the special chars are wrong. (Grüße -> "GrüÃ?e")

I have no more idea to solve my problem...

[Martin Trummer]

what does request.getCharacterEncoding() show?

if you use commons-file upload, you could try to manually set the
encoding
upload.setHeaderEncoding(encoding) --> to the same value you use in
your meta tag

[GWT-Newbie]

Yes, I'm using commons-file upload.

My meta tag is: <meta http-equiv="content-type" content="text/html;
charset=UTF-8">
request.getCharacterEncoding() shows "UTF-8"
upload.getHeaderEncoding() now also shows "UTF-8"

But still getting the wrong result. -.-

[Martin Trummer]

hm - works for me

maybe you should make a simple testapplication and post the
entry point class and a minimal version of your servlet

[GWT-Newbie]

Solved the problem :)

It wasn't the GWT making complications, the chars arrived at the
server correctly, but were misinterpreted by Apache Commons Fileupload
reading the items with the filItem.getString()-Method.
In addition to upload.setHeaderEncoding("UTF-8"), I had to add a
argument to every getString() method, which says, that he mustn't use
the american ASCII, but UTF-8. (fileItem.getString("UTF-8"))
Thanks for your attempt!

Happy coding.
