Where your geometries come from? Are they in some kind of spatial storage like a shapefile, Oracle Spatial, PostGIS, etc?
The way to obtain the featurecollection from your storage medium is to use a DataStore (think of it as the JDBC driver for your database, but in GIS) So, depending on where your features are, you have to use one or another. There are plenty of them on geotools and hopefully you'll find one appropriate. Read the following section on the user guide on how to use DataStores: http://docs.codehaus.org/display/GEOTOOLS/Data+Reading You may find a couple API differencies depending on if you're using version 2.2 or 2.3+ I can't remember if DefaultMapLayer expects a FeatureResults or a FeatureCollection, but anyways you can get the FeatureCollection from the FeatureResults.getFeatures() regards, Gabriel PS: I could have written something wrong, since I'm writing from the top of my head, but I guess you'll easily find the way through the user docs pointed out above.
