更新了两个错误，我都不知我当时在想什么。见谅。

加了2小节， Exception and testing.

sorry, the number is misleading. That's just my placeholders for different categories. So really, that's it, along with spring web, spring & ibatis, spring core.

When writing a topic, I think we have to have:
1. enough practice and interesting examples.
2. can see through the details to get the big picture.

So this is all I have now, no further plan yet. Some of the interesting topics are JCA, JMX, JMS.

spring对jms的支持不够深入（跟spring对persistance的支持比较起来）
感觉那个template不象template 就一个helper而已
所以现在有些lib在spring的基础上做了些jms的活 不过不敢用 毕竟好象没看到有人用
期待floater在这方面的高见

my understanding on jms is:
on the sender side, spring's jmstemplate is enough. The problem is on the receiving side. If there are a huge pile of msgs that need to be consumed, then single thread is not enough, and thus we want "concurrently" consume the msgs. The most currently used methods are:
1. session pool (google "weblogic session pool" for references). but this method is superceded by
2. mdb. However, the inflexibility of configuration of mdb(which is generic to ejb) is a pain too.
On the hint of Spring & POJO, there is a realization of the idea using POJO concurrently, like you said. We need more time to evaluate this. So for huge volumes of msg, mdb is the way to go, right now.

The idea of running POJO consumer concurrently is quite smart, it lays itself on top of JCA, which handles most of the concurrency and transactions (otherwise we have to do it). So I think this should work, the only thing left is to work out the details. With the help of JCA, this shouldn't take long(though this idea may take a little long).

my 2 cents.

thx
hmm....i guess i won't take time to find other solutions than mdb,
otherwise i need to convince my vendors, then workshops, then report to my boss...which might be a boring task.
p2p only, multiple producers with only one consumer, quite simple..isnt it?
