Set Tomcat default locale

To set default Locale in Tomcat you should edit the catalina.sh file found in the "bin" directory of Tomcat installation.

Look for something like:

JAVA_OPTS="$JAVA_OPTS....."

At the end of the JAVA_OPTS definitions add (for Enligh):

-Duser.language=en -Duser.region=EN

You'll get something like:

JAVA_OPTS="$JAVA_OPTS -Duser.language=it -Duser.region=IT"
