I have the need to tie in a content management system into my Spring/Hibernate/Acegi application and am curious to know what open source CMS packages integrate well with Spring. My application will provide auto-generated content as well as give the user the ability to manage content they push to the CMS. I would like the CMS to fully integrate with my application and will need to manipulate the CMS 'skin' so I can incorporate my own navigation and event items.

I looked at JNuke but it appears to be a bit unstable. I have looked at Alfresco but it appears to be too full featured and perhaps difficult to integrate. I have also started to consider moving my application from Tomcat to JBoss for the JBoss portal functionality. Finally, I have also started looking at the Spring Modules Jackrabbit integration as a possible CMS solution.

What have folks done with respect to CMS solutions that integrate well with Spring? Ideally, I would not like to roll my own CMS solution and rather would want to integrate my Spring app with a well proven CMS solution.

Thoughts, comments.

Thank you in advance for your assistance.
