I have been working with many web application frameworks (and with Grails as well), but in Grails I couldn't find the answer how to integrate my own Java libraries (that possibly use Hibernate and spring themselves) into Grails/Groovy project?
Also is there any possibility to separate presentation logic from business logic (just add some API calls in web layer to business)?
in a plugin I'd like to extract constants (e.g. folder and file names) into a (groovy) class for reuse in install, uninstall and other scripts.
How can I use such a class in my gant scripts?
