Next you need to grab a FeatureStore and called addFeatures; there is an
example of this kind of thing in the user guide. And we can add your
example here when we are done with it....

String typeName = myData.getTypeNames[0];
FeatureStore featureStore = (FeatureStore) myData.getFeatureSource(
typeName );
Transaction t = new DefaultTransaction();
try {
FeatureCollection collection = fs.getFeatures(); // grab all features
featureStore.addFeatures( collection );
t.commit(); // write it out
}
catch( IOException eek){
eek.printStrackTrace();
try {
t.rollback();
}
catch( IOException doubleEeek ){
// rollback failed?
}
}
finally {
t.close();
}
Give that a go (in case I got something wrong) and send me back the
completed code example so I can dump it in the user guide :-)
