Answer 1

Hello malcolmmc
Ok just let me know : (if i am wrong)
1] That is sure that using threadlocal as my central
context class wont give me any threats of
thread-safety as its used only in Service method of
servlet.It should be OK, however I think that a servlet container may pool threads which might mean that the context stored in the ThreadLocal for a transaction might not be null when the transaction starts (which may also delay the garbage collection of the context and anything it points to.
You should probably clear the value at the end of the transaction.

2] Using ThreadLocal is good for managing code. and
performance change is nothing (i tested it)
I don't think performance is going to be a big deal. I imagine that a ThreadLocal is simply a WeakHashtable with the Thread object as the key (I thought of doing this before I noticed ThreadLocal already existed). But there's probably a maintenance issue. It's something to flag up in your documentation.
3] How to set and threadlocal variable (reference) to
free its holding memory? is it var.set(null) works?Yup

4] also tell me how should i give u those 10 dukes
dollar?You should see a Duke symbol with a plus above each post in the thread other than your own.
