Need simple interface with one extra window

[redsky9 0]

Hi all.

I'm looking for a H5 simple interface that has one extra window that can be opened from the server side.

I am able to create a new window in the interface, but have no ideea on how I make it open from the java side.

If anyone has this kind of simple interface and wants to share it, or can point me in the right direction on how to do it, I would greatly apreciate it.

Thanks all and happy new year.
