Um. You mean "gameframe" not Jframe right? Jframe is the buttons and menus added to a client frame that does other stuff that aint related to ingame graphics. Gameframe is the images that you use for the inventory,tabs, and etc...
But anyway what you want is in the graphics sub-section of the RS Client section.

Just download the file there, and take out the sprite that you need.
