Using DBeaver plugins in Eclipse E4 RCP

[Syneltec]

Dears,

I am trying to write an E4 RCP application.
(newbee, using Vogel's book as reference)

I would like to use some DBeaver (very nice !) functionalities, such as, by example Connection Wizzard.

What I would expect to write is typically Command Handlers like that :

@Execute public void execute(Shell shell)
{
        NewConnectionWizard wiz = new NewConnectionWizard();
        WizardDialog wizd = new WizardDialog(shell, wiz);
        wizd.open();
        .....
        .....
}

I still have exceptions, but stepping into your code let me think that I am in the right way.
Is what I am trying to do correct ?

Does somebody have examples / documentation on how to use DBeaver in an application (a standalone eclipse program) ?
An API documentation, in fact.

Thanks in advance if somebody can help.
Charly.
