Can portlets developed for other portals be deployed on JBos

[brucespringfield]

Can portlets developed for Liferay or Websphere Portal Server as an example be deployed on JBoss Portal?

And can JBoss Portlets be deployed on other portals?

If they are JSR-168 (and soon JSR-286) compliant portlets, there shouldn't be any problem: compliant portlets will deploy (and work) on any compliant portal server.

That said, JSR-168 left a lot to be desired in terms of functionality so portal vendors often extended the standard with proprietary APIs. Obviously, any portlet that rely on such APIs will not work properly on competitors products...
