Can I use Spring-Roo without setting up a database?

You can set up a "dummy" database using HSQLDB which is an internal Java based database that takes up minimal resources. It will satisfy Spring Roo's persistence requirements, and you don't have to use it. Plus, it has a minimal overhead.

Since Roo works with data providers such as Hibernate you do have the flexibility to decide where you want to store your entities. If as you describe you have an existing database then you can configure this in the application so that a new database will not be required. You can specify your entities so that they load directly from the existing database.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
