Can @ unique () be executed inside Java in xpages?

When I want a unique key for a file, I prefer @ unique() I like it based on user name and time

Is there any way to get it from a java bean?

If not, what's the best way to get a unique number that won't be repeated in Java?

thank you

Solution

Yes, you can When you get the handle of the session call You can use this method to evaluate any formula expression

String ID = (String)session.evaluate("@Unique").elementAt(0);
