Java "Simple Persistence for Java is an open source object-relational persistence library that uses a custom query language and built-in database support to simplify object persistence in Java applications. In this article, software architect Sami Salkosuo introduces the library and walks you through its zero-admin, zero-config approach to object persistence."

Interesting project

I didn't like the article, but the library it describes looks very interesting. Make sure to have a look at the tutorial on the project's website, it was much more useful to me than that article with its overcomplicated example:

Production Ready?

- Very Nice looking...
But, why these obscure dependencies.
I'd be very nervous to implement this code in production.
Are these open source library api's set in stone or will they be redesigned in the next release? Why no use DERBY which is already in the Java namespace...

This is part of the problem of "open sourcing" java.
This code could stop working in 3 to 12 months.

That's simplicity and abstraction!

Very good, I am impressed. That's real simplicity and abstraction. Up until now, I have been avoiding using persistence layers in Java due to their complexities (I developed my own, which is a light API over JBDC with limited functionality).

This product, coupled with ThinWire (, can make programmers really productive...
