is knowing XML mandatory

[Omar Al Kababji]

Hi guys, I am preparing for the SCBCD and i am preparing for it from both the (O'Reily) Enterprise JavaBeans 3.0 and (Manning) EJB3 in Action, for now i don't look or try to memorize how to configure session beans, entity beans ... etc using XML, i just focus on java annotations. do I have to know XML mappings too? I have read the specifications and it is not that clear that knowing the XML mappings is a must.

Unfortunately it is mandatory to learn, as mentioned in the Exam Objectives. And yes, it is very hard to memorize those tags.

Thanks for the replay, this is something I was afraid of, I will have to memorize stupid XML mappings

It is not stupid. XML descriptors are useful for application assemblers, to override the annotations made by the bean provider.

Yes they are 100% good, but the stupid thing is that we are forced to memorize them ... no one memorizes how XML is written, unless you use it everyday. however after you finish developing your application then you could write the needed XML mappings to substitute the annotations so that you can make little modifications with no need to recompile the entire application, and this is great but memorizing the XML is not great.

Yes, I agree
