Hello,
I have written a simple primary key generator for my entity beans. (For people who are not aware of the primary key generator problem, please see this thread.)
It is a stateful session bean based on the HIGH/LOW principle. I have a pktable in my database (MySQL) which has just one auto_increment column. This column gives the High values. The I am pasting below is self explanatory.
Could anybody please be kind enough to critisize it? I want to know in what situation it might fail.

Why is this a stateful session bean..? There could be multiple instances of this bean, so the same ID may be served more than once. Do you intend the ID (key) to be unique across some space..?
I must be missing something.
