I've got embedded tomcat setup in pre-integration
test phase.
I need to create the same for in-memory database but before the embedded tomcat.
Are any easy&useful maven configuration examples for doing that (for example HSQLDB) ?
If you use google you would have found something like this:
https://github.com/avianey/hsqldb-maven-plugin
which exactly is a maven plugin which seemed to be right choice for what you like to do. The plugin is also available from Maven Central.
