Tame Wild EJBs? (chapter 13)

Hello authors,

Could you elaborate a bit regarding the content of chapter 13, titled "Tame Wild EJBs" ?

Can I assume this may cover the caveats of having POJO based EJBs and not about migrating from EJB 2.0 beans to EJB 3.0 beans? (which I'm guessing is what the following chapter covers)

thanks,
Dario

Actually it is primarily for tuning entities and EJB components (sesssion beans and mDBs).

Here is the detailed TOC for Chapter 13:

Understanding locking types 458 ■ Optimistic locking and
entity versioning 461 ■ EntityManager and lock modes 462
13.2 Improving entity performance 464
Remodeling and schema redesign 464 ■ Tuning the
JDBC layer 468 ■ Reducing database operations 470
Improving query performance 474 ■ Caching 478
13.3 Improving performance of EJB 3 components 483
Session bean performance 484
Improving MDB performance 487
13.4 Clustering EJB applications 488
Collocated architecture 489 ■ Load-balancing stateless
session beans 490 ■ Clustering stateful session beans 493
Entities and clustered cache 495
13.5 Summary 496

Thanks Debu,

I was hoping (judging by the title) that it was about anti-patterns and such but advanced tuning and performance tuning techniques are always good topics. I'm especially looking forward to 13.4: Clustering EJB Applications. Would this include more than general clustering design topics with specific example code and configuration for specific EJB container(s)?

thanks again,
Dario

Design patterns and anti-patterns are described in Chapter 12
