JSR 170 specifies a standard API to access content repositories in Java
independently of implementation - see
http://jcp.org/aboutJava/communityprocess/final/jsr170/index.html.
JSR 168 is the portal spec, revolves around portlets - if you write a
portlet based on JSR 168 you would get interoperability between portlet
containers offered by different vendors - see
http://jcp.org/aboutJava/communityprocess/final/jsr170/index.html
As you can see both are different.I see Magnolia Web content management
system a Web CMS that supports JSR 170, so in future e.g if you wanted to
move from one content repository, e.g database to a filesystem you could.
I dont see it as a portal, it doesnt support JSR 168, doesnt provide a
portlet container etc. A good example of open source portal offering is
liferay, www.liferay.com
Typically in most web application projects this is a crucial architecture
decision to be made, ie do you need a portal based system, web cms or both.
Both of them focus on the presentation layer, Web CMS's focus more on the
content and its lifecycle. In addition something like magnolia offers
support for JSR 170 so your implementation is not locked to one underlying
content repository.

Subject: [magnolia-user] JSR 168 vs. JSR 170
Can anyone explain the difference between the CMS specification JSR 170
and the Portlet specification JSR 168? Could Magnolia be considered a
Portal? If so, is it compliant with JSR 168?
Any links or suggested reading material would be appreciated.
