I use a JSP errorpage from content frame and popup window and i need to reload the menu frame in both case.

I try this : parent.menu.location.reload() but this give me an error from the popup window.

Try this :

(not sure if reference returned by window.opener is reference to the hole window or to the frame window that actually opened the pop-up window)

It ofcourse only works if you used window.open() method to show your pop-up window.
And check first if the element exists before you call its sub items/properties/methods to avoid errors :)
