Geo tools and other options?

This is my scenario. I have the latitude and longitu开发者_运维百科de of certain places in a CSV file.I now want to be able to show these points on a map. say for example on the US map.I tried converting this CSV file to shape file and tried to use the geo-tools to do this, but am missing some jar file which am unable to figure out.What are the other good options for solving this problem?

You should maybe take a look at mapwindow or QGIS if you just want to see the points on a map.
