I started using Stripes for work and side projects a while back and have been impressed with its simplicity. Their Javadoc documentation is solid, but finding workable examples is tough. There’s a great book by Freddie Daoud that walks through creating an application, but it only goes so far. I spent too much time Googling for the proper place for persistence.xml, for example. Lately I’ve had occasions in troubleshooting behavior where it would be beneficial to back out to a dead simple project to test how something should work.
