| How to tell RAP to switch perspective from external servlet ? [message #77621] |

Hi,
On startup our app is opening a default perspective containing a maximized
viewpart that serves as a login page.
This login page is implemented using browser widget backed by a plain
servlet. Now if the user is successfully logged in the servlet must tell
RAP to switch to the main perspective containing the core business
application.
But in the login servlet I'm kind of lost since I don't know how to
contact the RAP.
Is this scenario possible at all ?
Thanks in advance for any advice.
Regards,
Setya

Hi Frank,
I'm sorry for being too slow on this.

So from your suggestion I should have the following code in my
IEntryPoint#createUI():
public int createUI()
{
Display display = PlatformUI.createDisplay();
HttpSession httpSession = RWT.getSessionStore().getHttpSession();
Runnable runnable = new Runnable()
{
public void run()
{
//How to obtain the reference to IWorkbenchWindow at this stage ?
IWorkbenchPage page = window.getActivePage();
IPerspectiveDescriptor perspective = page.getPerspective();
perspective = window.getWorkbench().getPerspectiveRegistry()
.findPerspectiveWithId("main.perspective.id");
page.setPerspective(perspective);
UICallBack.deactivate("my.entrypoint.classname");
}
};
httpSession.setAttribute("key.display",display);
httpSession.setAttribute("key.runnable",runnable);
UICallBack.activate("my.entrypoint.classname");
return PlatformUI.createAndRunWorkbench(display,new CoreWorkbench());
}
I still can't see how I can obtain reference to IWorkbenchWindow at this
stage.
Or maybe I should create and store the runnable in
WorkbenchWindowAdvisor#postWindowOpen ?
public void postWindowOpen()
{
Runnable runnable = new Runnable()
{
public void run()
{
//Obtaining the reference to IWorkbenchWindow
IWorkbenchWindow window = getWindowConfigurer().getWindow();
IWorkbenchPage page = window.getActivePage();
IPerspectiveDescriptor perspective = page.getPerspective();
perspective = window.getWorkbench().getPerspectiveRegistry()
.findPerspectiveWithId("main.perspective.id");
page.setPerspective(perspective);
UICallBack.deactivate("my.entrypoint.classname");
}
};
RWT.getSessionStore().getHttpSession().setAttribute("key.runnable ",runnable);
super.postWindowOpen();
}
And finally in my login servlet :
protected void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
//Perform login authentication here
boolean success = validateLogin(request.getParameter("user"),
request.getParameter("password"));
if (!success)
{
getServletContext().getRequestDispatcher(IPluginXmlConstants .WEB_CONTEXT +
"/login.html").forward(request,response);
return;
}
Display display = (Display)request.getAttribute("key.display");
Runnable runnable = (Runnable)request.getAttribute("key.runnable");
display.asyncExec(runnable);
}
Or am I missing something here ?
Regards,
Setya

Hi,
from my understanding of what you want to do, it makes no difference,
whether you create the runnable in WorkbenchWindowAdvisor#postWindowOpen
or directly in IEntryPoint#createUI(), since the code of the Runnable
gets executed in one of the subsequent requests from the servlet. At
that point of time the workbench is already up an running. So feel free
to create the runnable in WorkbenchWindowAdvisor#postWindowOpen(), if
this is for any reasons your prefered place.
Ciao
Frank

OK.
So I should create the runnable inside
WorkbenchWindowAdvisor#postWindowOpen ?

Hi,
why don't you use the following?
IWorkbench workbench = PlatformUI.getWorkbench();
IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
Ciao
