Hi. I think you have a really nice blog.

That is really cool …if it is true.

I agree with Zeger’s quote from Johnson too – there are simpler ways. Just use JDBC to get from the sequence, perhaps?

He even calls this solution “unworkable”!

Instead, he suggests alternative unique ID generation mechanisms, for example using the facilities of the Java language (by using an algorithm based on e.g. random numbers, system time, network traffic, or etc.). This is a fast and portable solution!

More info on this topic can be found on page 271 of his book.
