PSA: J2EE and .NET Reloaded

The latest version of the .NET & J2EE Petstore is now available from The
Middleware Company
.  You can discuss on
the ServerSide.  I won't give a long
rant here, other then to say that TMC, by now, have probably the best industry knowledge
of tuning J2EE applications.  There test matrix is huge, incorporating
OS, app server, database, JVM version, JDBC driver and this doesn't even include what
technology the app was developed using EJB, servlets, etc. 
Really interesting read....
