exactly, i was interaction directly with the mapcontext, saw some results, but
couldn't do no pan.
idea is that from the entire mapcontext, i do some zoom-in on a small specific
area just like the zoom-in button from the toolbar does. i just have to specify
the coordinates of the position i want to make the zoom.
another way i thought i could do it was the use of a mappane:
mapPane = new JMapPane();
mapPane.setRenderer(new StreamingRenderer());
mapPane.setMapContext(map);
Envelope env = mapPane.getDisplayArea();
double width = env.getWidth();
double delta = width * 0.3 * 1;
env.expandBy(delta);
mapPane.setDisplayArea((org.opengis.geometry.Envelope) env);
mapPane.repaint();
maframe = new JMapFrame();
maframe.add(mapPane);
...
but it didn't work either. :(

What Every C/C++ and Fortran developer Should Know!
Read this article and learn how Intel has extended the reach of its
next-generation tools to help Windows* and Linux* C/C++ and Fortran
developers boost performance applications - including clusters.
