Take a look at the code snippets available at:  http:// 
svn.geotools.org/udig/branches/1.1.x/udig/tutorials/ 
net.refractions.udig.code.examples/src/net/refractions/udig/code/ 
examples/

It shows how to create a temporary layer which you can use to copy  
features to.  It also get features from the source layer.  Finally it  
shows how to create a new resource and add it to a map.

This is just a simple eclipse extension that you need to make.  Add a  
dependency to your plugin on net.refractions.udig.mapgraphic and  
save.  Then switch to the Extensions tab of your Manifest.MF editor  
and add a mapgraphic extension.  Fill out the form and create the  
MapGraphic implementation.  It is a simple interface.
