One war calling another in Tomcat
<p>I am currently implementing a small application A. This application A gets some objects from users and will do some preprocessing, before it passes these objects into a different web application B, which finally will store information of these objects.</p>

<p>Now to the question: What are possible approaches to call application B from application A? And which one is the most efficient (in terms of run-time speed)?</p>

<p>This call is one-way, possibly can be done asynchronous and always will happen in the same tomcat server.</p>
