How can I do off screen rendering using LWJGL?

I'm trying to find a way to do rendering off screen with LWJGL. What I want to do is render something and keep it in memory as a texture, then at a later point use that to texture a shape I'm drawing in the main window. I'm pretty sure this should be done using a Frame Buffer Object, but I haven't been able to find any useful documentation online. I'm fairly new to Open GL and LWJGL so I'm sure there is some fundamental concept I'm missing.

Could someone possibly provide a simple example that renders something(I don't really care what) off screen to a texture? Ideally I would like to end up with a slick-util Texture object.

Create a frame buffer object and bind it as the primary render target. Here is a tutorial:
