message box in server side javascript

Actually at the starting of our Xpage, Every faced this problem...

How can we get the message box in server side?

Yes there is a lot of solutions for that...

1. We can create a panel as message box and use Hide when formula (css - z-index)...

2. Use Dojo dialog.

3. I tried to make a unique and nice way, Finally I have one great idea.

That is we can create a Jpane for message box single line code,


JOptionPane.showMessageDialog(null,"Message");

We can use documentcontext for calling this agent and we can use this code for validation too...

I think this is one of the nice idea for validating our current document.,
