UTF-8 encoded request URI

[Lulseged Zerfu <zl...@hotmail.com>]

Hi  I am getting bad request from tomcat when I send UTF-8 encoded request to my application. I have configured connector in my server.xml with URIEncoding=”UTF-8”. I have set charset in the request to UTF-8. How can I solve 400 Bad request? How can I tell tomcat to decode request URI instead of responding with 400 Bad request? I will appreciate any help.
I am using tomcat 8.0.11 on windows 8 x64. I have also tried with tomcat 7.0.55. BRLulseged

Hi.

To post to this list, you should probably set your email program to send messages as 
"plain text". That would make it easier to read them.

About your question :
If Tomcat responds that the request is invalid, then it probably is.
So the question is not how to make Tomcat consider it as valid, but rather how to generate 
a valid request, from the client side.

You do not provide the real request that results in such a Tomcat response, so it is 
difficult to tell.
If I had to guess, I would guess that it is the page in which there is the link that you 
click, to generate this error in Tomcat, that is not correct.
Maybe the page says that it is UTF-8, but the link itself (in the "<a href=...> that you 
click on) is in another encoding, or vice-versa ?  It may also be wrongly URL-encoded.

Unfortunately this is not always within our control.  I've been seeing 
the following in my log files recently:
java.nio.charset.IllegalCharsetNameException:'UTF-8' caused by different 
User Agents like "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; 
Trident/5.0)" and "Amazon CloudFront"

It happens when I try to get the request headers.  I don't have a full 
stacktrace or more details because I am not logging that ATM, but I can 
add it to the logs if needed.

Don't send an invalid request.

You can't. Tomcat will always reject invalid requests with a 400 response.

Again, read this:
http://www.catb.org/esr/faqs/smart-questions.html

Then try asking your question again and provide enough information that
someone on this list stands some chance of being able to figure out what
the error is.

Can you give an example of the request?  Are the non-ascii characters in
the URL or in the payload of your request (or both)?

Not necessary with Tomcat 8.  The default for URIEncoding is "UTF-8".
 Unless you have set the system
property org.apache.catalina.STRICT_SERVLET_COMPLIANCE=true.  That will
override the URIEncoding and set it to "ISO-8859-1".

I have set charset in the request to UTF-8. How can I solve 400 Bad

You seem certain that the 400 error is due to the encoding.  Perhaps it's
something else?  What have you done to troubleshoot this?  Have you tried
stepping through things with a debugger?
