You are probably looking for this:

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("viewId");

In e4, the EPartService is responsible for opening Parts. This can also be used to open e3 ViewParts. Instantiate the following class through your IEclipseContext, call the openPart-Method, and you should see the Eclipse internal browser view.

public class Opener {
    @Inject
    EPartService partService;

    public void openPart() {
        MPart part = partService.createPart("org.eclipse.ui.browser.view");
        part.setLabel("Browser");

        partService.showPart(part, PartState.ACTIVATE);
    }
}

Here you can find an example of how this works together with your Application.e4xmi.

I found the need to bring the view to the front after it had been opened and pushed to the background. The activate method does the trick.

PlatformUI.getWorkbench()
    .getActiveWorkbenchWindow()
    .getActivePage()
    .activate(workbenchPartToActivate);

NOTE: The workbenchPartToActivate is an instance of IWorkbenchPart.

If called from handler of a command

HandlerUtil.getActiveWorkbenchWindow(event).getActivePage().showView(viewId);

would be better, as I know.
