I am looking for a way to compile CSS LESS files on the server side on demand during development. For example if the browser makes a request to /assets/css/foo.css I want the server to notice that there is an /assets/css/foo.less file and then to have this file complied and the resulting css returned. I am guessing there must be a LESS servlet somewhere that can do this?
I am running tomcat 7 with Spring MVC application
How do I configure a Java Web App to do on the fly LESS compilation?
I think what you are looking for is a Servlet Filter. I was not aware of an off the shelf one that does LESS compiling and would have started to make one using lesscss-java, but now I can see there is a larger project called Web Resource Optimizer for Java – wro4j with server side LESS support.
