setting JSTL locale "java.util.MissingResourceException"

[sabelosimelane]

I have an application that runs well on my local machine but when I deploy it on the server I get a "java.util.MissingResourceException" exception. I am using JBOSS, JSTL and spring. I have tried to use these pieces of code:

<fmt:setLocale value="en_US" />

I have also tried this in my web.xml

<context-param> 
        <param-name>javax.servlet.jsp.jstl.fmt.locale</param-name> 
        <param-value>en_US</param-value> 
    </context-param>

When I debug locally the locale is "en_US" but when deployed to the server the exception shows that it's actually "en_ZA". Is there a way I can force this locale on the server to look for "en_US" just like it is locally? Could someone help please?

This is my stack trace:
