This blog post continues the Great Application Server Debate series, in which we have already covered IBM Liberty Profile, Jetty, Tomcat and JBoss. Today we’re talking about GlassFish. As with previous posts, we will be reviewing the application server purely from a developers point of view.
GlassFish is the reference implementation for Java EE, originally developed by Sun Microsystems, and now owned by Oracle.
The world of app servers has traditionally been split between servlet-based containers and enterprise (Java EE) servers, with Tomcat being the clear winner in the servlet-based container space and WebSphere and Weblogic sharing the Java EE mantle. Typically servlet-based containers are used significantly more than Java EE servers, almost 60% of the respondents to our survey use at least one servlet-based container. Below you can see last year’s Developer Productivity Report results on Application Servers:
In the last half of 2012, the big dogs were trying to become more nimble and agile, while the quick Tomcats of the world are trying to add more of the Java EE feature set. The addition of the Liberty profile to the WebSphere line of products represents a shift in the mindset of traditional enterprise users, and developers are clamoring for a faster way to get as close to a production environment as possible on their local machines.

Plus, they deploy new versions during the day, with all staff available, in case something breaks.Read more
