Hi,

A component in one DC can commmunicate to other compoment in some other DC.

-> Create a child DC, Make the necessary parts as public.

-> Interface Controller helps two components to communicate. So create context in Interface controller, and map it to the component controller's context.

-> Now, Build and Deploy the child DC.

-> In parent DC, define the used DC, and used component. Now the interface controller of childDC's component will be available in Parent DC's component.

-> Now Map the context of Interface controller, of childDC's component, to component controller of parent DC.

Hi Mastanvali,

You need to create 2 DCs.

The component that you want to use of DC1 in DC2 expose it in the public parts of DC1.

In DC2 select the exposed component of DC1 in the used DCs in DC2.

Now you can communicate between 2 DCs.

Hi,

A WebDyn Pro Project can not directly comminucate with another WebDyn Pro Project.It can be done through Dc's.For example you can declare the component as apublic part in the first WebDyn Pro Project and you can use it in the WebDyn Pro Project with the help of Dc.

Here are some links about Dc's.Check these links they maybe helpful to you.

Hi,

Two Web Dynpro projects never communicates.

Two components in different projects can communicate. Each component have a controller. You need to create usage relation between component and then use controllers to communicate.

See my reply in this thread: shows a scenarion of communication between components in different dc projects:
