Java EE vs. Net--middleware Company (companies engaged in the education promotion of Java) test knot

1. This evaluation is not m$, but the Java (mainly the EE) promotion and training of middleware company (I admire such companies can be to their disadvantage of the data published) made (see a lot of effort), TheServerSide.com was assisted in the evaluation.
2. The comparison of the products is still their respective petshop (all 2.0), this time. NET's petshop to change the stored procedure to dynamic SQL, and EJB stood on the same starting line.
The Java Petshop,middleware optimized it, and the optimized petshop2.0 performance (maximum throughput) was 10 times times that of the original petshop2.0 (Sun) (visually visual, (-:). Interested in understanding the optimization of Java EE can go to see the middleware of the original code.
3.J2EE this side has two servers, using two JDK, the result: if you are not using the jdk1.4 (in fact, compared to the ability of the JRE), then change to 1.4 as soon as possible. In the 1. In the 3 era, Sun's JDK was only the third. Now IBM is still 1.3 (better than sun1.3), a lot worse than sun1.4. sun1.4 1.3 has a 50% promotion!
4. Disclaimer: The Linux operating system used by the sun server on this side may say why the Solaris (64B) is not being used, which was asked on the theserverside. The same Intel platform is used if there are no truly validated 64b versions using SOLARIS,MST. Compaq servers (with a good server, 8cpu.4g Ram).
He also compares the performance of Java application Server on redhat7.2 and Win2000 (Win2000 is selected).
5. They did not say what the use of Java application Sever, but according to the price and he said that the industry's best two look, I think is weblogic,websphere,bas.oracle9ias two of them, there will be WebLogic, After all, the industry has the highest market share.
Database: The Oracle 9i,driver used by. NET for SQL Server2000,java is type 2 (best performance, native code), as if it also uses thin (type 4) but certainly no type
