I just read your original post and that error is exactly what I was referring to in my last post. The problem is, by default, the database shuts down when the jvm shuts down. So, if you want to dynamically restart jetty, you need a way to shutdown the db if the jvm is not shutown. You can do as I described in my last post, using sbt, but there are other options. I'm not sure if that will work with mvn.
H2 comes with a DbStarter [1] ServletContextListener that will start up and shutdown the db. It can also start up a tcp server, if you need that. However, it requires you to specify the db url, user, and pass as context-params. Which is a show stopper for me. There is only one line in DbStarter that one would really need and that is a sql statement that is sent to the db. This code is in the contextDestroyed method. So, if there is a way in Lift to call some code when the servlet context is destroyed, then one could put that sql statement there and manually shutdown the db. I realize you use Derby, but I'm guessing that it works similarly. So, Lifters, is there a way to call some code when the context is destroyed? Or, is there another way to accomplish this?
