Call a method of a portlet from another portlet of a different project

[Anuvab Ghosh, geändert vor 7 Jahren.]

Hi,

I am using Liferay 6.1. I want to call a request method from another portlet of different portlet-project.
There is two different portlet projects, Project I : A-portlet and Project II : B-portlet.
I want to call a request method of B-portlet from a button of A-portlet .jsp file.

Both war files of the projects are deployed in the same Tomcat server.

Please tell me how to meet this requirement.

Thanks in advance.

Thanks and Regards,
Anuvab

Have you tried server side or client side IPC if your requirement matches.

Hi Anuvab, If i understood your question. You're trying to call one method, that belongs to the portletA, and you want call that method in portletB. If it is, look this page: http://www.liferaysavvy.com/2015/09/java-reflection-in-liferay.html

I hope that you can solve this issue

But portletA and PortletB both are from different portlet projects.

Look at <liferay-portlet:renderURL> tag. For example, here:

Sorry, but this really just means you have not encapsulated your business logic correctly. You're trying to build in some sort of dependency on an instance class from another portlet, one that you will not have any expectation that the portlet has been instantiated and the class has actually been loaded and ready.

When you have these kinds of dependencies, you must structure your application to isolate them from portlet instantiation.

For example, you could create a simple ServiceBuilder layer with a service entity (an <entity /> definition with no columns) and build the methods in there. They are isolated from the portlets and can be invoked at any time.

But for your predicament, it's practically impossible to do what you want because you have no real control over what is available when.
