When you use the fixed pipeline, the projection is already managed for you by glFrustum/gluPerspective and glOrtho. When using the programmable pipeline, you can emulate the fixed pipeline with some JOGL build-in utilities (PMVMatrix, FixedFuncUtil, ...) or do it by yourself (optionally with our utilities to manipulate the matrices as float arrays). Of course, you can use a dedicated matrix to store the projection.
