Text rendering using SWT port 0.7.0 of JOGL

OpenGL Development JOGL Development

Hello,
I am using the SWT port 0.7.0 of JOGL (or JSR 231, don’t really know?!). I would like to use the following methods of com.sun.opengl.util.j2d.TextRenderer:
begin3dRendering()
draw[b]3d/b
end3dRendering()

However, none of these seam to exist, and the sole that are available are the 2d versions (beginRendering(), draw() and endRendering() ). Did I make a mistake or is it a common problem for those who work with SWT?

I then tried to use gl.glBitmap with that worked fine on AWT:


gl.glNewList(i + fontOffset, GL.GL_COMPILE);
gl.glBitmap(charWidth, charHeight, xorig, yorig, xmove, ymove, rasters[i - 32], 0);
gl.glEndList();

With the SWT GLCanvas, I got:


Exception in thread "main" javax.media.opengl.GLException: Method "wglGetExtensionsStringEXT" not available
	at com.sun.opengl.impl.windows.WGLExtImpl.wglGetExtensionsStringEXT(WGLExtImpl.java:393)

	at Text3D.<init>(Text3D.java:13)
	at MyGLTest2.main(MyGLTest2.java:65)

I tried removing the last argument , since the original open gl function has only 7 inputs (see http://www.glprogramming.com/blue/ch05.html#id5452091). Actually one can also use a GL.glBitmap function with a com.sun.opengl.util.BufferUtil as input instead of a byte[]. However, I have the same exception!

Any idea someone?

One last question: what are the differences between com.sun.opengl and javax.media.opengl?

Thanks!
