The org.apache.catalina org.apache.catalina.connector property was used to set UTF-8 encoding in the Wildfly 10 configuration. These properties have no impact since Wildfly now uses Undertow.

In order to set UTF-8 encoding instead of changing:


<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>


Editing the standalone.xml as follows


/{WILDFLY_HOME}/standalone/configuration/standalone.xml


Add: system-properties tag



Edit:  servlet-container

<servlet-container name="default">
