Resolving spring:messages in javascript for i18n internationalization

I'm attempting to internationalize some of our code. I have a page in JSPX which is using the <spring:message> tag to resolve strings from a message.properties file. This works fine for the HTML and CSS that is in the JSPX page, however there a javascript file is sourced, and substituting the <spring:message> tag for the string in there just means that it gets printed out verbatim.

My JSPX sources the javascript like so:

<spring:theme code="jsFile" var="js" />
<script type="text/javascript" src="${js}" />

The JS where I'm looking the replace the string is below:

buildList('settings', [{
    name: '<spring:message code="proj.settings.toggle" javaScriptEscape="true" />',
    id:"setting1",
    description: '<spring:message code="proj.settings.toggle.description" javaScriptEscape="true" />',
    installed: true
}]);

And finally the message.properties is something like:

proj.settings.toggle=Click here to toggle
proj.settings.toggle.description=This toggles between on and off

So what I'm wondering is, should this work? It seems to me like it should, from what I've gathered on various forums, but I can't figure out where I'm going wrong. Is there a better way to go about this?

I should also note that these files are outside the WEB-INF folder, but by placing the ReloadableResourceBundleMessageSource in the root applicationContext.xml the spring tags are picked up.

Thanks for any help!
