Utilizing a file named messages.properties with JSTL format messaging has been effective for server-side Java and JSP applications. However, when it comes to incorporating JavaScript, the need arises for the same messages in a format that is compatible with JavaScript. One potential solution is to maintain two separate files, one formatted for Java and another for JavaScript such as JSON. Do you have any suggestions or insights on how this integration is typically handled in practice? It's important for the variables from Java code to be accessible to JavaScript, although the current method may not be the most elegant solution.
