Hi David,

What are the three things that other servers (like Tomcat and Weblogic)dont have and Glass Fish does? Why should any company put in effort to move to this application server, in your opinion?

Does your book elaborate on this?

Thanks,
S Hasan.

S Hasan,

Tomcat is not a full fledged Java EE application server, it is a servlet container. Therefore using Tomcat alone it is not possible to develop and deploy applications taking advantage of Java EE 5 APIs other than servlets, JSPs and JSF.

Although I haven't used any recent versions of Weblogic, at least in the past Weblogic had the tendency to try to trap you into their proprietary APIs, making the transition to other application servers difficult.

Also, GlassFish is free, support is available for about $4,000 a year, regardless of how many CPUs the server where it is deployed has (don't quote me on this, contact your friendly Sun sales representative for the actual price ), and Weblogic, last time I checked, cost about $50,000 per CPU (again, contact a BEA sales representative for an actual quote).

David
