Applications in RAP [message #894128]

RAP supports multiple applications that allow multiple entry points. From the Java doc, these applications can be looked up from the Platform, and we have one and only one workbench. Is it true to say that no matter how many entry points we have, they are all sharing one workbench and all the perspectives that are registered? Say, if I have two RAP applications, it would be wrong to assume that they can have their own perspectives without interfering each other, and work as if they are two separate RAP applications (but just a different URL)?

Thanks so much.

Ronald

Hi Ronald,

If you utilize the Eclipse Workbench in your RAP applications/entry-points then each user gets their own workbench instance, which gets stored in the user's HTTP session.
Calls like PlatformUI.getWorkbench() will return the instance of the workbench created for the particular user session asking.

Hi Ronald,

Multiple RAP applications are only supported for plain RWT applications
that don't use the 3.x workbench. There is only one single instance of
the extension registry that is shared between all applications.

It's true to say that all registered perspectives are shared among all
entrypoints. But there is one workbench instance per user session.

Right, that's not possible for workbench applications. If your
applications don't rely on the workbench, but only on SWT and JFace, it
is possible to have multiple completely isolated applications.

Regards, Ralf
