Because both transactions are in the lock acquisition phase, neither one releases a lock prior to acquiring the next one. Recovering from a deadlock situation
I would like to explain threading deadlocks to newbies. I have seen many examples for deadlocks in the past, some using code and some using illustrations (like the famous 4 cars). There are also cl...

Update : This is one java example I found on web (Oreilly book ...
