JDesktopPane problem

[atiqlodhi]

I am using JinternalFrames in JFrame(JDesktopPane). I am getting
difficulty in navigation in them...Let us say I have two
Jinternalframes student & courses. I can set links to them from JFrame
by using JMenubar. But when I try to set their link (as a requirement)
inside Jinternal frame like From Student JinternalFrame when a button
clicked it opens Course JinternalFrame in JdesktopPane but In Student
JinternalFrame i did not have accesisbility of JDesktopPane instance to
do work

have any suggestion please post it soon with details(and if possible
with example)

Regards
Lodhi
