Java Flavor???

Hi All,

I want to go on Java training as my next assignment requires application development using Web Dynpro and IView development using Java. I wanted to get your output as to which training course will be the best to go for. Should I go for regular Java or Java server pages(JSP) or the Enterprise Java beans(EJB). Can someone recommend anything and tell me which flavor of java is used with Web Dynpro and which one is used with Java IView development?

Thanks in advance.
