Do you know anything about the next version of EJB, like EJB 4.0?
I started to learn EJB 3.0 and I see that there is much to read and practice. I'm wondering if I will make it before the completely new EJB will come and shift me to learn many redesigned things again.
I haven't found much about the next version in the internet... Somebody has any info or a link?
Keep in mind that it may still be up to 2 years before the Java EE 6 specification is finalized. I know the original target was 2008, but if you look at the current state of things this seems highly unlikely. After the Java EE 6 specification has been released, it may take up to 2 or 3 years for all major vendors to implement this. Just look at the current situation with Java EE 5. Also, it may take up to 5 years for the Sun certification exam to get updated to EJB3.1 and probably up to 7 years for books to get updated. With a little luck, books about SCBCD for EJB3.1 will be in stores around 2017.
Assuming EJB4 comes right after EJB3.1, do the math yourself when a SCBCD for EJB4 will appear. If the current pace of advancement continues in the future, something like around 2025 may be a conservative estimate.
Basically what I'm saying is that you probably have some 17 years to go without having to worry about EJB4
