Hi All,
I have an application where in which from ZUL file I make calls to the composer classes and from composer classes the DataBase related (DAO) classes. If any exception occures in the DAO layer I am catching and throwing as MyApplicationException with proper exception message and error code.

Now I want to show this message (which was used while building the exception) in a popup with ok button.
Is it possible?
If yes how?

Thanks in advance.

I tried the example given here.

But every time on the server logs I see following:

Am I missing something?
