. Net background scea (Sun Certified Enterprise architect, 310-052) Suggestions

Microsoft has its own MCA, but this seems too unattainable. At least 10 years of experience, 3 C-level member recommendations, 10000 $ examination fee and rush test fee are both a great burden.

The development field may be scea, but it is oriented to the Java EE background.

Fortunately, in terms of the scope of the scea objective question (310-052) examination, the technical concept gap is less obvious than that of P and D. Here are some of my experiences.

 

1. The 310-052 New Technology for Java ee 5, even involving EJB 2.1 is only part of the study of EJB 3 vs EJB 2.1

2. Even if you do not have a Java EE background, you can use the following analogy:

JPA -- LINQ. The advantage is that M is used to achieve database independence, more Oo, and easier migration. It can also provide internal provider support, TX, and dtx for the cluster. Using a method similar to lamada in JPA, you can also provide a variety of search, projection, and selection, and can bulk update, insert

JMX--WMI, system. Management. If you see instrument (Do you still remember entlib) and monitor, you can consider it for O & M

JSF--WPF. It also supports C/S, B/S, m/s, event-driven, State Mgmt. It can provide better Ajax integration, and is easy to organize the existing web.

The JMS--WCF adopts the MSMQ mode. Asynchronous processing, reliable delivery, and support for P2P and pub/Sub. If you see the event, notification can be considered.

EJB 3 Session Bean -- COM + non-Q mode or WCF adopts the net TCP mode. Containers provide a series of services, such as Tx, security, and distributed.... However, for environments with extremely high concurrency and be complexity, we recommend that you customize stateless Bean + Dao without integrating JPA.

RMI, RMI--.NET remoting. This platform is called, but RMI can be compatible with CORBA with IDL, and RMI provides TX support.

JCA--WCF adapter. Adapter + container provides sec, TX, and concurrency support for external platforms.

The Web Service of the JAX-WS--WCF or a common web service. It is implemented through attribute (annotation) and stateless. If you see the appearance of C ++, Perl, COM and other words, you can consider using this technology to expose them through ws packaging.

JNLP -- system. Configuration: access the configuration file.

3. In fact, the pattern part has a majority of 310-052 concepts. From the perspective of the subject, it mainly refers to what should be used in a specific situation. This requires us to focus on the context and forces part of the gof23 eight-unit system, you can ignore the structure and subsequent content. In addition, 310-052 involves 13 Java EE architecture models (15 previous J2EE versions). Refer to core J2EE patterns.

4. Others

SAAJ: If you see soap and attachment, consider it.

Seej: If you see that the TCP connection is used to process the Security processing under the application layer, you can use this secure socket technology.

5. References

After reading it, I found that additional books are of no use, and they will only be used.
