Reduce frequency of deployments in a Java web application using Spring-MVC

Question

Is there a simple way to have your "Service Layer" deployed separately from your web layer, so that I can reduce the number of times per week that I have to, package, build and deploy the entire WAR file?

I'm using Tomcat mostly, but I'm hoping for something more generic to Java web servers.

Answer 1

If the package-build-deploy process is necessary, but heavyweight enough that you want to minimize or avoid it, you might also consider making that process easier, faster, or more automated.

Answer 2

You could move your "service layer" to a second application and have the front-end application communicate with the "services" using some sort of remoting technology.

Spring Remoting (a.k.a. HttpInvoker) makes this very simple to use.
