Today I faced an interesting problem at work. It was JSP + Spring MVC 4 + Apache Tiles 2 + JBoss AS 7.1 application. JSP pages contain UTF-8 encoded Russian text encoding and should be displayed in UTF-8 in browser. I placed @Page directive in some pages:
<%@page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
Pages with above directive started to display non-English text perfectly fine. Others continued to show me unreadable rubbish instead (in default JBoss ISO-8859-1). So I already had a solution:
Solution 1 – modify every JSP page in the project to add proper @page directive.
But my idea was to not configure every page separately. I opened JBoss standalone.xml and put the following fragment at the end of the file before the </server> closing tag:
<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>
.. and caught JBoss startup error JBAS014789: Unexpected element '{urn:jboss:domain:1.2}system-properties' encountered
After some surfing I found an interesting resolution: on some versions of JBoss <system-properties> should be placed below <extensions> section. I put it there and got my UTF-8 working. My final standalone.xml looks like that:
Solution 2. Put <system-properties> section just below <extensions> in standalone.xml:
<extensions>
<extension module="org.jboss.as.clustering.infinispan"/>
<extension module="org.jboss.as.configadmin"/>
<extension module="org.jboss.as.connector"/>
<extension module="org.jboss.as.deployment-scanner"/>
<extension module="org.jboss.as.ee"/>
<extension module="org.jboss.as.ejb3"/>
<extension module="org.jboss.as.jaxrs"/>

</extensions>
<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>
