Below is the specific information of my exam, where SCWCD and SCDJWS are taking the beta version. Personal views: I feel that for beginners, the test certification can accelerate the speed of learning knowledge, I am a beginner, For many years, there is no practical use of certification, although I have passed SCEA, but I have not reached the level of SCEA.
The following experience: I haven't forgotten the difference. SCJP: This is the basic knowledge, but it is necessary to pay attention to the trap. Different threads and garbage recovery I think it is difficult. SCWCD: This is easy, mainly is very familiar with Web.xml, and It is very clear about taglib. I have been taking Beta, so the official version is unclear. SCBCD: This is the main EJB-JAR.XML, and there is a definition and responsibility of various roles, and it is the life cycle of EJB. SCDJWS: this My score is the lowest, there is no say, just say a few words, mainly for SOAP, WSDL, UDDI, XML, XML Schema specification, should be familiar with the standard document, and some of the SUN's support for WebService is clear. Such as JAX-RPC, Jaxr, Jaxb, Saaj, etc. Alternative to EJB, how Servlet is the SCEA of WebService: This I have the highest score, but I don't have the right to say, because I don't reach the level of SCEA, brief introduction experience It is a big aspect, so it is understood that various systems should be understood, and a scene will generally give you a scenario, so you have to know the feasibility of various solutions and The second part is relatively simple, the key is that you have to fully understand the needs, and more design patterns may be high.
I all searched on Yahoo Group and the Internet.
Loyal, I wish each test-certified friend good luck
