18. You need to learn how to manage and configure a J2EE application server such as WebLogic, JBoss and so on, and take advantage of its additional services, such as cluster-type, connection pool, as well as support for distributed processing. You also need to know how to above in its application package and configuration and can monitor and adjust its performance.
19. You need to be familiar with the programming aspect-oriented and attribute-oriented programming (both have been very easy to confuse the abbreviations for the AOP), as well as the mainstream of their specifications and the implementation of JAVA. Such as AspectJ and AspectWerkz.
20. You need to be familiar with the different API and a useful frame work for you and so on. For example, Log4J (logging / tracing), Quartz (scheduling), JGroups (networkgroupcommunication), JCache (distributedcaching), Lucene (full-textsearch), JakartaCommons and so on.
21. If you will be docked or being and the old system or the local platform, you need to learn JNI (JavaNativeInterface) and JCA (JavaConnectorArchitecture).
22. You need to be familiar with JINI technology, and with it related to distributed systems, such as master CROBA.
23. You need JavaCommunityProcess (JCP) as well as his different JavaSpecificationRequests (JSRs), such as Portlets (168), JOLAP (69), DataMiningAPI (73), and so on.
24. You should JAVAIDE such as a master sunOne, netBeans, IntelliJIDEA or Eclipse. (Some people prefer to write VI or EMACS file. Not what you use:)
25.JAVA (said to be some precise configuration) is lengthy, it needs a lot of manual code (for example, EJB), so you need to be familiar with code generation tools, such as XDoclet.
26. You need to be familiar with a unit testing system (JNunit), and learn a different generation, deployment tools (Ant, Maven).
27. You need to be familiar with JAVA development in frequently used software engineering process. Such as RUP (RationalUnifiedProcess) andAgilemethodologies.
