Can I call GL methods outside of GLJPanel callback?

I have an app where I've created a GLJPanel for rendering, passed it a GLEventListener object and use that object to render stuff to the screen.  While this works for most of my rendering, it is a pain to use with textures.  I'd like to be able to create and initialize textures outside of the GLEventListener callback.  I'd also like to be able to write render-to-texture code that also does not have to depend on GLJPanel getting around to calling GLEventListener.display().  However, I need to make sure that the GL objects I create share the same context so that my main rendering loop can use the textures that I'm manipulating outside of it.  Is there a way to do this?

Shared Context:

  - Also check our unit tests

Outside GL invocations:
  - Look at GLAutoDrawable.invoke(boolean wait, GLRunnable glRunnable)
