nono...
it's about how to write performance-aware java
such as stringbuffer instead of string, factory instead of instances

performance bottleneck在数据库，Java programming把memory usage管好就行了。

LOL, I think a good starting point to improve
your ejbs' performance is stop using them.

How is ejb3's performance, they look like spring bean and I expect
similar performance, shouldn't be bad right?

I don't have first-hand experience with ejb3
so I can't really comment on it.
Although I think that the performance problem
of classic ejbs mostly comes from not the
wiring, but the invocation boundary - all
the marshalling/going over the wire/unmarshalling,
which probably hardly changed in ejb3.
It's not really that bad for stateless session
beans though, their API being very coarse
grained.

Right, EJB3 is a waste, IMHO

EJB3还是可以的,从Spring那儿学了不少好的东西。EJB3.1 light weight EJB会更有点
意思.

偶是被Sun的玩意儿吓怕了。每次Sun推出的东东，总是感觉笨重，而且不合developer
的要求，呵呵
