How do I properly receive UTF-8 characters in JBoss 7? - encoding

Question

I’m using JBoss 7.1.3. Currently, when I submit a request to the server with a special character, for example
Café
it is received by the server as
Café
The only piece of advice I found online for correcting this was to add these sysmte properties to $JBOSS_HOME/standalone/configuration/standalone.xml …
<system-properties>
…
<property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>
<property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>
</system-properties>
However, even after restarting my server my special characters are still being received incorrectly on the server side. What else can I do to properly interpret the characters?

Answer 1

The thing that fixed the encoding for me for the JBOSS versions 7.1.0 beta or higher was to include the following line to the standalone.conf file directly under the bin
JAVA_OPTS="$JAVA_OPTS -Dorg.apache.catalina.connector.URI_ENCODING=UTF-8"
OR
Try the following in the standalone.conf directly under bin or domain.conf whichever might suit you
-Dfile.encoding=UTF-8
*Works for version 7.1 JBOSS

Answer 2

The e-acute is U+00E9.
Encoding using UTF-8, you get 0xC3 0xA9.
If you convert that on the assumption that your terminal or whatever is using cp1252 or similar, you get é. Solution: don't do that. Tell your jboss to use UTF-8.

Answer 3

have you tries following option?
set start up param ,
-Dorg.wildfly.undertow.ALLOW_UNESCAPED_CHARACTERS_IN_URL=true

Answer 4

Try setting org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING to false.
Had the same problem very recently, the above config being true was the core issue on Jboss EAP 6.4.0.
It seems that no matter what you set in URI_ENCODING, if USE_BODY_ENCODING_FOR_QUERY_STRING is set to true (and body has no encoding) it will default to ISO-8859-1.
As in tomcat docs: https://tomcat.apache.org/tomcat-8.5-doc/config/http.html (look for useBodyEncodingForURI connector attribute).

Answer 5

Had the same issue in JBoss 6.4. JVM was correctly set, displaying special characters was ok, but the POST requests were encoded in ISO-8859-1.
Someone put a filter which set the encoding without luck.
request.setCharacterEncoding("UTF-8");
In the end the issue was that this filter was not the first to be executed. What I did what to put this "UTF8 filter" in the first position and it solved the issue.
The trick is that the fist filter executed set the encoding. It seems that another filter did set the wrong encoding.
The class implements javax.servlet.Filter with the following code:
public void doFilter(ServletRequest inRequest, ServletResponse inResponse, FilterChain inFilterChain) throws IOException, ServletException {
inRequest.setCharacterEncoding("UTF-8");
inFilterChain.doFilter(inRequest, inResponse);
}
