Companies adopting J2EE are considering switching to Microsoft. NET?

In the morning, I received a newsletter from Microsoft's partner and had a connection. The original Article is as follows:

Advocates who understand why J2EE-based companies are considering switching to Microsoft. netjava often claim that Java outperforms Microsoft platform in terms of portability or vendor neutrality. In the latest expert column, Tim landgrave will show you how to prove that this is not the case.

The author is obviously an employee of Microsoft. He analyzed several questions carefully?

1. Many people like Java. Many companies adopt J2EE as a persistent direction. Is it because of Java's portability?

If yes, this oneArticleThe idea is clear. in theory, Java can have good portability, "One Java, run anywhere ". in real life, Java implementation requires different vendors to implement, and various vendors are not all cool.ProgramMember. if the preceding description is an interface, you will find that in addition to implementing interfaces, multiple vendors also add many of their own features. otherwise, everyone is now using the same interface, so it is not very competitive in terms of functionality :)

2. If Java porting is not considered, is. Net suitable for enterprise applications compared with J2EE?

This may require some. Net basic components and methodological support. At present, this field has many

3. It seems that everyone is not willing to compare. NET 2.0 and Java 5.0.

I have read some materials and feel that the two are getting closer and closer to each other in terms of basic features. However, I think this should not be a major focus of enterprise applications.
