Hi Darmawan, Really all that happens with the zoom in and zoom out cursor tools is that they work out the new map bounds (as a ReferencedEnvelope) and then call JMapPane.setDisplayArea.
Perhaps the easiest thing for you to do is look at the source code for ZoomInTool, ZoomOutTool, and their base class AbstractZoomTool. You can find them all here... http://svn.osgeo.org/geotools/tags/2.6.0/modules/unsupported/swing/src/main/java/org/geotools/swing/tool/ When using ZoomInTool you can draw a box on the map pane with the mouse to define the area to zoom in to. The code that draws the box is part of the JMapPane class so you don't need to implement that yourself.
