I’m doing a project in Vaadin 7. In that I need to implement something like below for the login.
A user ‘A’ is logged in to a system ‘1’. And again he logs into another system ‘2’. Now I want to know how to close the UI on the system ‘1’.
I tried something and can able to close the UI, If it is the same browser. But, for different systems/browser. I don’t have any idea.
My Code:
private void closeUI(String attribute) {
for (UI ui : getSession().getUIs()) {
if(ui.getSession().getAttribute(attribute) != null)
if(ui.getSession().getAttribute(attribute).equals(attribute))
ui.close();
}
}
Can anyone help me in this?
