True, i should have posted it right at the beginning. But i was shure it is a very prevalent mistake The problem is that the column that should not be null is not inserted at all (visible in the second listing).
Ou I mixed a course with a certificate, which is good First i thought this one is the new SCJP certificate. Earlier there was a good coloured picture on the sun page with the certificate blocks. Is there any existing now? Can someone post a link please?
i try to gain experience in enterprise systems and search for an interesting open source project that i can contribute to.
My list of wishes It is understandable that it is probably impossible to find a project with all of the following points but with some of them i will be happy as well
some backend stuff (JDBC and Hibernate are welcome)
Btw experienced in svn & cvs, ant & a little bit maven, eclipse. My native language is German but i think it is great to have a chance to improve English too, if the project language is German it's ok ;)
Please contact me if you know something or even if you are searching someone for your own project.
i started to work with EJB3.0 and JBOSS as well and i use "Enterprise JavaBeans 3.0 (5th Edition)" and couple other books. I like this book but in my opinion there is no ONE book to find that explains all topics very good. Buy three or four and sell a couple after understanding the stuff. Good luck
