We use Tomcat to host our WAR based applications. We are servlet container compliant J2EE applications with the exception of org.apache.catalina.authenticator.SingleSignOn.

We are being asked to move to a commercial J2EE application server.

The first downside to changing that I see is the cost. No matter what the charges for the application server, Tomcat is free.
Second is the complexity. We don't use either EJB nor EAR features (of course not, we can't), and have not missed them.

What then are the benefits I'm not seeing?

What are the drawbacks that I haven't mentioned?

Mentioned were...

JTA - Java Transaction API - We control transaction via database stored procedures.
JPA - Java Persistence API - We use JDBC and again stored procedures to persist.
JMS - Java Message Service - We use XML over HTTP for messaging.

This is good, please more!
