Please look at the Java documentation. javax.media.opengl no longer exists, it has been renamed:
https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/index.html?overview-summary.html

Those methods are in the fixed pipeline, you'll find them in com.jogamp.opengl.GL2ES1, GL2, GL3bc, GL4bc and GLES1.
