Problem with DC to DC communication

Question

Hi All,
I have totally 3 DC's. first and second DC's have a button. On click either of these buttons in 1st and 2nd DC's, 3rd DC application should open.

This is my requirement. Please suggest how i can proocede on this. With step by step procedure for this.

HI
For this you can pass the parameter while navigating from one DC to the other and then check the value of parametr to know from where it is coming.
In the eventhandler of the button action of first and second DC you can put the following codes respectively.
First DC
  String frompara = "frompara=first";
    String str = "ROLES://<here write the PCD location of the iview of third >";
    WDPortalNavigation.navigateAbsolute(str,WDPortalNavigationMode.SHOW_HEADERLESS_PORTAL,
     WDPortalNavigationHistoryMode.NO_HISTORY,frompara);
Second DC
String frompara = "frompara=second";
     String str = "ROLES://<here write the PCD location of the iview of third >";
        WDPortalNavigation.navigateAbsolute(str,WDPortalNavigationMode.SHOW_HEADERLESS_PORTAL,
        WDPortalNavigationHistoryMode.NO_HISTORY,frompara);
IN the third DC, you can put the following code in the wddoinit method
Third DC
String str = WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("frompara");
     if(str.equalsIgnoreCase("first"))
          wdContext.currentContextElement().setSeltab("Tab");
     else if(str.equalsIgnoreCase("second"))
          wdContext.currentContextElement().setSeltab("Tab1");
here in third DC we will bind the context attribute Seltab to the selected tab property of the TabStrip UI element.
This will solve the problem.
