  12. The TMC team spent 4 months performing this benchmark. They worked 100 hours per week on this and worked every weekend, skipping holidays. Trust me, they were trying very hard to make J2EE win. But in the end, J2EE did not come out on top. TMC had a lot of heartache seeing the results of this benchmark. We internally debated about whether we should post this or not. In the end, we decided to go forward and publish this report. - The Middleware Group, October 2002

  13. PerformancePetshop Case Study • Java Pet Store is Sun’s primary blueprint application for J2EE • Source: http://java.sun.com/j2ee/blueprints • Illustrates best coding practices for J2EE • Ships as a sample application in IBM Websphere, Oracle Application Server 9i, Sun iPlanet, and BEA WebLogic • The .NET Petshop is a port of the J2EE Java Pet Store to .NET • Source: http://www.gotdotnet.com/compare • Implements the same functionality as Java Pet Store • Illustrates best coding practices for .NET Framework

  19. Broad Language Support J# String s = "authors"; SqlCommand cmd = new SqlCommand("select * from "+s, sqlconn); cmd.ExecuteReader();

  20. Broad Language Support VB.NET Dim s as String s = "authors" Dim cmd As New SqlCommand("select * from " & s, sqlconn) cmd.ExecuteReader() C# string s = "authors"; SqlCommand cmd = new SqlCommand("select * from "+s, sqlconn); cmd.ExecuteReader(); C++ String *s = S"authors"; SqlCommand cmd = new SqlCommand(String::Concat(S"select * from ", s), sqlconn); cmd.ExecuteReader();

  21. Broad Language Support var s = "authors" var cmd = new SqlCommand("select * from " + s, sqlconn) cmd.ExecuteReader() JScript Perl String *s = S"authors"; SqlCommand cmd = new SqlCommand(String::Concat(S"select * from ", s), sqlconn); cmd.ExecuteReader(); Python s = "authors" cmd =SqlCommand("select * from " + s, sqlconn) cmd.ExecuteReader()

  25. Broad Language Support Scheme (let* ( (s "authors")   (cmd (new-SqlCommand (string-append "select * from " s) sqlconn))) (execute-command cmd)) local       s: STRING       cmd: SQLCOMMAND do      s := "authors"       create cmd("select * from " + s, sqlconn)       cmd.ExecuteReader() end Eiffel ExecuteReader = invoke System.Data.SqlClient.ExecuteReader(); SqlCommand = create System.Data.SqlClient.SqlCommand(String,\ System.Data.SqlClient.SqlConnection); query = sqlconn -> let{ s = "authors"; } in {    cmd <- SqlCommand ("select * from "+s, sqlconn);   cmd # ExecuteReader();    }; Mondrian

  26. You have to manage it by ignoring it. The complexity of J2EE is pretty extreme…There’s a dirty little secret about J2EE; most people don’t need J2EE; the JSPs and database APIs are enough ….If you need to use it, then use it; if you don’t, stay away. - James Gosling (the “father” of Java”), May 2002

  27. InfoWorld: So what you're saying is what J2EE adds in terms of Web services support in 1.4 could be relatively irrelevant? Mills: Yes. That's exactly what I'm saying. - Steve Mills, IBM chief software executive, April 2002

  28. Though in theory, any J2EE application can be deployed on any J2EE-compliant application server, in practice, this is not strictly true. - Oracle’s web site

  29. Due to the vendor-specific tools and extensions required for ease of development, functionality, performance, and integration, Java 2 Enterprise Edition (J2EE) application servers still lock users into a specific vendor's product, despite being based on standards. - The Meta Group

  30. The .NET Bet • Software industry transformation • Integration and XML • Decentralized computing • New user experience • User confidence in privacy, security • Windows 2000 foundation • Subscription business models • Partnerships
