[HELP] Can't not submit unicode form by ajax action in Struts + Velocity framework

Hi all,

I got a trouble when I submit the unicode form by ajax.

when I test the submitted url, it gives me the right unicode value for each 
parameter I sent. ex: xxxx.do?st1=tốivề&st2=ngàyvề

but when I retrieve it from bean, it was not unicode value :(

this trouble happens only when I submit one form by ajax action, when I do 
it with normal struts action, it's okie, I mean I get all unicode values.

I think that there's something wrong when the Struts servlet receive the url 
(GET methods)

help me, thanks in advance

bowlkhin,

PS:
*****************************************************
++++ in web.xml, I use SetCharacterEncodingFilter class to convert string to

just out of curiosity have you implemented your Ajax Control with RPC or doc-literal or some other type of transport?
Thanks,

If you want to send special characters in the URL you have to encode them.
Anyway I know how to do it in Java, using URLEncoder.encode(myString, 
"UTF-8"). I don't know if there is such a feature in JavaScript...
Just a question, why don't you "post" those parameters?
