Hi Nikhil,
Looking at the class, I beleive you can override it if you want to --
after all, it is an OSGI Service.
@Component(immediate = true, service = DynamicInclude.class)
public class MBPortletHeaderJSPDynamicInclude extends BaseJSPDynamicInclude {
.. but, being an internal class, unless you do some OSGI tickery as
David has blogged about https://community.liferay.com/blogs/-/blogs/fixing-module-package-access-modifiers you
would be stuck having to make a copy of the class. It's not an ideal
solution because it means that you would miss out on any future
updates without manually checking for changes.
I am confused though -- you said that you can't override the jsp with
a fragment. I think you might be mistaken on that point. You should be
able to, but there are two types of fragments. There is a simpler one
with just the bnd references, which I presume you have tried. That
will not work, as you say.
The other is overriding a portal core JSP which is used for just this
type of scenario: https://dev.liferay.com/de/develop/tutorials/-/knowledge_base/7-0/overriding-core-jsps
I've done this a handful of times so that should get you what you need.
