Looks like you have a PRJ file:
PROJCS["World_Robinson",GEOGCS["GCS_WGS_1984",DATUM["
D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]
],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION[
"Robinson"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],
PARAMETER["Central_Meridian",0.0],UNIT["Meter",1.0]]
If you would like to check if GeoTools can understand your PRJ file you can
uses CRS.parseWKT( String ) method.
There are examples here:
