Due to security reasons our legacy application is split into 2 web applications, one application is for front end and another one for business logic and database interaction, i.e. middle tier.
I am redesigning this application now using the Spring MVC with JSTL. The tutorial examples are for 1 application.
What should I do to configure this spring application that uses JSP’s in a separate war?
I’ll go this way:
With that architecture, your first WAR accesses second WAR services through AJAX calls. That implies intense use of JavaScript: maybe you can use JQuery to help you with that.
Also, that approach let you deploy WARs in different containers. And even the first WAR can’t be a WAR at all and it could be even a PHP application deployed in Apache or a plain HTML/JS web page.
