We have grails application that is damn good. Grails application will be run under tomcat/jetty. I'm looking for a good (preferable java-based) CMS which could be deployed to same webserver and integrated with our application. Our app provides some data (xml/json) and we need that CMS display this data on some static pages (I'm thinking of java-script gadgets that just connects to our grails same-host-same-port-different-context app).
If someone know some other techniques how to easily embed data into CMS static pages - would be nice to hear.
