“Two software applications which are worthy of a mention are IBM
WebSphere Application Server and Apache Tomcat. IBM’s offering is
available in a community edition that is released under a free to
use and distribute license, but it is based on Apache Geronimo
which is featured below. Apache Tomcat is, in fact, a web container
not a fully fledged application server. A web container is the web
component of a web server that interacts with the servlets, Java
classes that extend the capabilities of servers that host
applications access. Nevertheless, Tomcat avoids some of the
overhead associated with full-featured application servers.“To provide an insight into the quality of software that is
available, we have compiled a list of 7 impressive open source
application servers. Hopefully, there will be something of interest
here for any organisation that wants a layered architecture.”
