There is a movement in the enterprise to port J2EE applications to lightweight Java containers such as Tomcat. This is part of the Agile development movement. There are many ways to tackle this port. You can just code some services up in lightweight Java. Or you could just write the new stuff in lightweight Java.Techniques such as SOA are complex. Java frameworks now offer a lot, but have a small code footprint. There are multiple lightweight Java containers. Tomcat from Apache happens to be a free and popular one. This may be the way of the future. Developers are tired of running under app servers like WebSphere.
